1. Introduction
Transportation comprises the displacement of people and objects for a specific purpose. The fulfilment of the relocation operations, which are supposed to be useful, is also called transportation [
1]. It is an important factor and serves social, economic, political, and population mobility that grows and follows developments that occur in different sectors and fields [
2]. Transportation systems are considered to be the lifeblood of cities [
3].
Public transport (PT) is referred to as transportation by a conveyance that provides continuing special or general transportation to the public. It includes different types of modes, such as rails, buses, trolleys, subways, and ferry boats [
4]. PT systems operate along lines that were determined months or weeks before the journey [
5]. Furthermore, it can be described as a shared passenger transportation activity that is suitable for public use, like the movement of goods and people to fulfil the primary needs of communities that require access and mobility [
6]. It is a high-capacity vehicle sharing system that serves as the backbone of urban transport networks, particularly in densely populated areas [
7]. It plays a key role in accommodating public travel needs, and its ability to move people around makes it extremely significant [
8,
9]. Moreover, PT networks are key factors in urban structure that enable elements of urban interactions and circulations to be improved [
10].
The main purpose of PT accessibility evaluation is to make the connectivity of locations and people easier in order to decrease the congestion on roads [
11]. PT reduces the external costs of driving private vehicles, but numerous urbanites prefer not to use it [
12]. Door-to-door service packages play a vital role as a feasible alternative for a private car [
13]. Therefore, PT should be accessible and safe for everyone in order to encourage both the use and further development of a sustainable transport system [
14]. It is significant for improving commercial and industrial life in a region, increasing labour markets, and reaching environmental goals. Municipalities also emphasised that road traffic should be minimised in favour of walking, cycling, and PT. Reducing the number of cars leads to reduced traffic congestion, lower noise levels, better air quality, reduced overall environmental impact, and better public health [
15]. PT also has another remarkable benefit in that it allows individuals to be less stressed, remain relaxed, and potentially read or rest while travelling [
16].
PT directly affects the quality of life of local communities and performs the required function for social, economic, and business development in large urban centres [
17]. One of the purposes of PT in urban areas is to improve commuting. Therefore, employment rates may increase due to a rise in job accessibility [
18]. The impact of PT on daily life is presented in
Table 1 [
15].
Although PT has advantages, it also has some disadvantages, such as time wastage, uncomfortable conditions, crowded services, unreliability, uncertainty of time, long waiting times, need for transfers, traffic, lack of flexibility, and long walking times [
16].
One of the previous studies emphasised that air pollution concentrations achieve higher levels in the absence of a PT system [
19]. On the other hand, the rising number of cars in Northern Cyprus is also arguably the source of dangerously high levels of carbon dioxide emissions per capita. In 2017, the number of registered vehicles increased by nearly 66% compared with 2015, including registered vehicles of around 182,709 and non-registered vehicles of approximately 109,665 [
20].
The migration from rural areas to urban areas causes problems due to the incremental growth of the population in recent years, and population growth leads to an increment in travel demand [
1,
21]. The rising number of cars and growth in urbanisation lead to traffic congestion in urban centres and, subsequently, to the occurrence of more traffic accidents. Road traffic accidents are a substantial public problem in the world and have become a major cause of death among young adults in many societies. Both developed and developing countries care about road accidents because of their effect on economic, social, and health issues [
22]. Developed public transit systems are not only needed for better public services, they are also required to minimise personal vehicle usage [
23].
Sustainable PT has become complex all over the world as a result of economic, social, political, cultural, and technological developments [
24]. A commonly observed trend was that the need for PT grew steadily over time. It has become a must in increasingly congested metropolitan centres due to traffic congestion and since people no longer choose to own cars [
25]. Road traffic congestion is one of the most common transport problems in urban areas due to the reduced liveability and attractiveness of cities [
26]. It has always been the main policy goal of transportation authorities to explore ways of promoting public transit [
27]. PT is a strategic choice in order to construct an environmentally friendly society [
28]. Sustainable transportation has three main goals:
Limits waste and emissions within the planet’s capability to absorb, reduces non-renewable resource consumption, and reduces the production of noise.
Operates efficiently, offers a choice of transportation mode, and supports a vibrant economy.
Allows the basic access needs of individuals and societies to be met safely and in a manner consistent with human and ecosystem health [
3].
Table 2 describes how sustainable PT contributes to the development of environmental, economic, and social life [
3].
This study was conducted to determine the intentions of people living in Northern Cyprus regarding PT within the framework of the theory of planned behaviour. This research finds out or detects users’ satisfaction with the efficiency and quality of the offered PT facilities. The effects of attitude, subjective norms, and perceived behavioural control on intention were evaluated, and their effects were seen. The results obtained from this study can be used to maintain and develop current transportation facilities in the future.
2. Literature Review
Redman et al. [
29] conducted a study in order to provide a greater level of understanding of aspects of PT quality to attract car users. They attempted to determine which quality attributes of public services are attractive to users and what changes in the quality attributes of PT services could encourage a modal shift from private motor vehicles to PT. They followed two stages to evaluate the research questions. Firstly, an analysis was conducted of how the quality of PT is defined according to the review of studies on the quality of PT, how it is evaluated, and how it can be improved to increase ridership. Secondly, empirical studies measuring the effects of PT improvements were analysed, considering the specific improvements targeted and then focusing on studies that targeted car use. The study findings indicated that reduced fare promotions and other habit-interrupting transport policy measures can encourage car users to initially test PT services.
Ambak et al. [
21] conducted a study in the region of Batu Pahat and Kluang in Malaysia. PT is important for daily life in Malaysia. This study presents behavioural intention for using PT, mainly public bus-based transport, based on the theory of planned behaviour. A questionnaire survey was used as a research tool, and 282 respondents completed the survey in order to identify factors that contribute to and influence users to use public buses and to determine the factors that are most effective using the TPB model. Regression and correlation analyses were also applied for this study. The results of the study showed that education is the primary factor in the use of public buses, and the frequency of public bus usage was 1–5 times per week. The study results indicated that attitude was found to be the factor that most affected the respondents’ use of public buses. On the other hand, most of the survey participants preferred to use public buses, as they are a cheap alternative for travel that can generate cost savings compared with private vehicles.
Saif et al. [
11] conducted another interesting study in order to review the existing literature about PT accessibility. They focused on the relationship between PT and other aspects of social life. The review study included PT perceived accessibility, PT accessibility and public health, PT accessibility and employment rates, PT accessibility and social exclusion, PT accessibility and mobility, PT accessibility and sustainability, and PT accessibility and economical, spatial, and temporal efficiency. The study concluded that the effect of PT on other social aspects should be taken into account in PT facilities, not only PT performance.
Shaaban and Maher [
8] focused on the theory of planned behaviour and aimed to investigate the possible usage of future metro services by applying a questionnaire-designed survey in Doha City. Qatar is confronted by high traffic demand, poor infrastructure, and limited land. Therefore, the country is constructing a new metro system in order to minimise traffic congestion and meet transportation needs. The theory of planned behaviour was followed to detect the intention of people to use the upcoming metro according to their attitudes, perceived norms, and sense of control. At the end of the study, it was found that perceived behavioural control was significant for residents in terms of using the metro for work and not for leisure.
Brohi et al. [
30] worked on the factors that affect commuters’ behavioural intentions for using the Karachi Circular Railway in the Karachi metropolitan area and investigated the most effective factor by using the theory of planned behaviour. A questionnaire survey was used as a research tool to categorise variables that affect users’ intentions to use the Karachi Circular Railway. A total of 240 respondents contributed to the survey. Cronbach’s alpha values were also used to check the reliability of the questionnaire. At the end of the study, most of the respondents agreed that they would choose to use the Karachi Circular Railway because it could save money and provide comfortable, environmentally friendly, and satisfactory services.
Rezaimoghadam [
31] aimed to investigate the impact of the theory of planned behaviour variables on citizens considering the use of PT vehicles. Questionnaire research was conducted in Gorgan, Northern Iran, and 650 questionnaires were delivered to different schools in the region. Then, students gave the questionnaires to their parents to respond. A total of 362 of the questionnaires were collected, and 339 of them were approved. Subsequently, statistical data were analysed using SPSS V23 software. According to the study findings, attitude is the most important factor that affects intention to use PT. The results of the study also emphasised that those who used PT more frequently were more aware of its benefits than others.
Borhan et al. [
32] conducted another study in Libya. The theory of planned behaviour was used to predict the travel intentions of car drivers with respect to new low-cost carriers (LCC). In total, 338 valid responses were collected for this study. Confirmatory factor analysis was used to analyse the data using the AMOS 21.0 program. The results of the study showed that the LCC service in Libya has the potential to attract the interest of people who tend to drive their own cars. The model of the study was well supported, and most hypotheses were confirmed. The results showed relatively good predictive validity.
2.1. Public Transport in Northern Cyprus
Transportation is served by road transportation in Northern Cyprus, and a railway system does not exist. Airlines and ferries are only used for travel purposes abroad. Since it is not a populous country, PT facilities are limited. There are no other choices offered in other countries here. PT is carried out with only bus and minibus services. Universities provide transportation services to their students who reside outside of the campuses or in different districts. Students are also able to benefit from on-campus ring services arranged during lecture hours. Transportation is a significant problem in Northern Cyprus, and PT issues have always been a challenge in cases where PT cannot provide a high level of service.
Figure 1 and
Figure 2 show the yearly number of recorded buses and minibuses, respectively, according to official country statistics [
33,
34,
35,
36,
37,
38,
39].
It is easily seen that the number of buses varies every year when the number of buses in the 2007–2020 period is examined. The number of buses has been on a regular, increasing trend since 2010. In 2020, the number of buses reached its maximum level. The increase in the number of higher education students contributed to this situation.
It is seen that there are not many minibuses in Northern Cyprus, according to
Figure 2. In fact, it seems that there were fewer minibuses in 2020 compared to 2007. This situation can be considered as minibuses being replaced by buses in the PT network.
Figure 3 shows the PT lines between districts of Northern Cyprus.
2.2. Theory of Planned Behaviour
The Theory of Planned Behaviour (TPB) was developed by Icek Ajzen in 1985 and is an extension of the theory of reasoned action [
21]. Perceived behavioural control was added to the theory of reasoned action to define individuals’ perception of the difficulty or ease of performing a particular behaviour [
40]. TPB has three main determinants: attitude towards behaviour, subjective norms, and perceived behavioural control [
41]. It proposes behaviour as a function of perceived behavioural control and behavioural intentions [
42].
It is a social-psychological theory that is used to quantify and describe how human acts are driven [
30,
43]. TPB is the most commonly used way of explaining human behaviour [
44]. One of the advantages of TPB relates to the possibility of increasing its potential to predict behaviour [
45]. It emphasises the importance of the individual’s attention and action while also understanding and predicting their attitude [
46]. People’s social behaviour is under the control of certain factors, resulting from certain reasons, and occurs in a planned way, according to the TPB. The goal of the behaviour can be measured, and the probability of its occurrence can be determined with TPB [
47].
TPB has been used to predict and explain diverse behaviours like weight loss, smoking cessation, social sciences, voting choices, committing traffic violations, transportation, choice of travel mode, recycling, physical activity, consumer behaviour, protection of privacy, and technology adoption [
21,
48]. Additionally, TPB also describes the psychological reasons for taking PT [
30].
The correlation between attitude, subjective norms, and perceived behavioural control with intention is depicted in
Figure 4. The figure also shows the impact of perceived behavioural control and intention on behaviour.
Attitude refers to the extent to which a person has an unfavourable or favourable evaluation or assessment of the behaviour in question [
49].
Subjective norms refer to the perceived social pressure to fulfil or not fulfil the behaviour [
49].
Perceived behavioural control refers to the perceived difficulty or ease of performing the behaviour. It also reflects previous experiences as well as obstacles and anticipated impediments [
49]. It plays an important role due to its ability to directly affect behaviour, but it does not always happen [
50]. Perceived behavioural control follows three different paths towards behaviour, which are listed below:
Explains behaviour through intention;
Directly explaining behaviour without the mediation of intention;
Description of both intention and direct behaviour.
An individual’s intention to perform a given behaviour is the central factor in TPB [
49]. It is considered an antecedent of behaviour [
51]. Intentions are indications of how hard people are willing to try and how much effort they are willing to exert. Intentions to perform different kinds of behaviours could be predicted with high reliability from attitudes towards perceived behavioural control, subjective norms, and the behaviour. When combined with perceptions of behavioural control, these intentions account for remarkable alterations in actual behaviour. On the other hand, perceived behavioural control with behavioural intention could also be used to directly find behaviour [
49]. It is the most important factor in the emergence and display of human behaviour [
50]. It is strongly related to behaviour, and it is considered that if intention can be predicted, behaviour can also be predicted [
52]. The possibility of showing actual behaviour will be higher if the behavioural purpose is stronger [
47].
4. Results and Discussion
The model refers to the current process and plan to provide evidence for scientific research or to answer questions. The models used in the research are very important, as they affect the whole process of the research [
50]. For this reason, it is aimed at determining the attitude, subjective norms, and perceived behavioural control variables of individuals and to what extent these variables explain the actual behaviour by evaluating them together with the intention. We first evaluated the descriptive statistics of the collected data, as presented in
Table 4. Then, we continued analysis with linear regression, including model summary and ANOVA test.
In terms of the participants’ gender, the majority of the participants were female, with a rate of 52.47%.
Most of the participants were in the 18–29 age group, with a rate of 67.53% when the age distribution of the participants is examined. As young people use the internet more frequently, this could be the reason why the 18–29 age group achieved the highest rate. Moreover, this is followed by the 30–39 age group with 16.88%, the 40–49 age group with 10.91%, the 50–59 age group with 2.34%, and the 60-year-old and above age group with 2.34%.
Most of the participants had graduated from university at a rate of 40.26%. High school graduates are followed by university graduates with a rate of 42.08%. There were also several Master’s/PhD graduates with 16.10%.
According to the participants’ place of residence, most of the participants lived in Nicosia, with a rate of 73.25%. As Nicosia has the highest population as the capital city of Northern Cyprus, this is an expected result.
Another demographic characteristic of the participants is their career information. It is evident that the questionnaire was largely completed by students, with a rate of 55.85%.
The purpose of the PT usage section has been divided into five categories: work, daily routine, education, entertainment, and none of them. Some of the participants chose more than one option in this section of the survey. As it can be understood from the fact that students mostly participated in the survey, the results show that PT is mostly used for educational purposes.
The frequency of PT usage per week as part of the demographic characteristics has been divided into four categories: 1–5 times, 6–10 times, 11 times and more, and never use. It is evident that the majority of the respondents never used PT. The second most chosen option was 1–5 times with 23.12%, followed by 6–10 times and 11 times, which both had rates of 17.66%, respectively.
Attitude towards behaviour expresses positive or negative feelings about using PT and was measured with the help of a total of 17 statements. Participants answered their beliefs about uncomfortable and unsatisfactory travel conditions in the attitude section of the survey. Expensive bus tickets, long time intervals between bus services, and long distances between bus stops and destinations were also mentioned. The survey suggested that buses were not frequent enough and the time spent travelling on a bus was unsatisfactory. Most users complained about the waiting time between buses and the travel time from their origin to their destination.
Table 5 shows the averages of the answers and the standard deviation of each statement. The answers were evaluated with the help of a five-point Likert scale. The mean values of the attitude are in the agreement tendency.
The subjective norm is the passenger’s thoughts about whether others approve of his or her use of PT and is measured with the help of a total of three statements.
Table 6 shows the expressions, the mean and standard deviation of the responses to each statement. The mean values of the subjective norms are in the agreement tendency.
Perceived behavioural control refers to the consumer’s perceptions of whether he or she can perform PT usage behaviour.
Table 7 shows the mean and standard deviation of the responses to each statement. The mean values of the perceived behavioural control are in the agreement tendency.
Intention shows how passengers are ready to try and how much effort they are willing to put into using PT in Northern Cyprus.
Table 8 presents the mean and standard deviation of the intention variables. The mean values of the intention are in the agreement tendency.
Factor analysis is a multivariate statistical approach to a single set of variables when a researcher wants to find out which variables in a set constitute logical subsets that are comparatively independent of one another. It is very helpful in determining the factor that underlines the variables by grouping related variables into a single factor. The Kaiser–Meyer–Olkin (KMO) test is a measure of whether data are suitable for factor analysis [
62].
Table 9 describes the KMO and Bartlett’s test results. The KMO measure of sampling adequacy is 0.533. KMO values below 0.6 indicate that the sampling is not adequate [
62].
Cronbach’s alpha is used to determine the reliability of quantitative data [
63]. It is commonly used to measure reliability in the educational, behavioural, and social sciences [
64].
Table 10 describes the reliability according to the different Cronbach’s alpha values.
Table 11 shows the Cronbach’s alpha values of each TPB variable. All TPB factors in the study are considered reliable to work on this study, as can be seen from the values in the table.
Attitude has high reliability.
Subjective norms have very high reliability.
Perceived behavioural control is reliable.
Intention has high reliability.
According to the literature review, confirmatory factor analysis and linear regression analysis are commonly used methods related to TPB topics. Since the KMO value is less than 0.6, confirmatory factor analysis is not appropriate for the study. Therefore, linear regression analysis was used in the research. Intention is the dependent variable of the model in linear regression analysis. Attitude, subjective norms, and perceived behavioural control are the predictors of the studied model.
Table 12 shows a summary of the model. According to the results, 32.2% of intention is explained by attitude, subjective norms, and perceived behavioural control.
The ANOVA test is another aspect of the regression analysis.
Table 13 presents the ANOVA test result of the TPB model. According to the results of the regression analysis, the cause–effect relationship is statistically significant between attitude, subjective norms, perceived behavioural control, and intention.
Table 14 describes the results of linear regression analysis. The following commentaries can be achieved:
The predicted path from attitude to intention has a negative influence. The attitude-to-intention path is not statistically significant (β = −0.015, p > 0.001). Therefore, attitude is not a predictor of intention. As a result, hypothesis 1 (H1) is not accepted.
The predicted path from subjective norms to intention has a positive influence. The subjective-norms-to-intention path is statistically significant (β = 0.438, p < 0.001). Therefore, subjective norms are predictors of intention. It increases the intention to use PT. As a result, hypothesis 2 (H2) is accepted.
The predicted path from perceived behavioural control to intention has a positive influence. The perceived-behavioural-control-to-intention path is statistically significant (β = 0.305, p < 0.001). Therefore, perceived behavioural control is a predictor of intention. It increases the intention to use PT. As a result, hypothesis 3 (H3) is accepted.
Table 15 summarises the decision on each hypothesis, and
Figure 7 clarifies the β (regression coefficients) in the TPB model.
6. Conclusions and Discussion
Sustainable transportation infrastructure is critical because of its significance to most organizations, governments, and residents when cities are growing. The study aims to investigate PT usage intention in Northern Cyprus, highlighting critical problems facing this sector that are fundamentally similar to those faced by many other countries. A questionnaire survey was conducted via the online method, and 385 responses were collected to achieve this purpose. Demographic characteristics were collected initially. First of all, young people use PT more than other age groups. University students and graduates are mostly those who prefer to use PT. Generally, it is preferred for educational purposes. The highest PT usage rate has been observed in Nicosia, according to collected demographic data.
The study explored different hypotheses to determine PT usage intention in Northern Cyprus. Therefore, the authors analysed the online survey data with SPSS V27 to check the influence of attitude, subjective norms, and perceived behavioural control on intention. As a result, subjective norms and perceived behavioural control have a positive influence, while attitude has no influence on the model. Theoretically, this study supports two elements of the TPB in explaining the intention to use PT. Based on the study’s findings, the following conclusions can be drawn:
Attitude has been detected as non-predictor of the intention to use PT. This is an expected result because of the undeveloped PT facilities and current PT issues in Northern Cyprus. People’s intention to use PT behaviour decreases when PT issues increase and PT conditions are undeveloped. Uncomfortable travel conditions contributed to the attitude result. Ali et al. [
65] said that if the major goal of a PT system is to attract a decent number of car users, it is critical to provide a reasonably good quality of service. On the other hand, Langi et al. [
66] emphasised that safety, peer pressure, ease of information, physical and financial condition, and time bound are different factors that should be primarily considered in order to increase the reuse of public transport. More passengers will be encouraged to use PT with better PT facilities.
Subjective norms were detected as the strongest predictor of intention to use PT, with the highest β value. Therefore, most people think that participants should use PT, according to respondents.
Perceived behavioural control has an influence on intention, but it was found to be the weakest predictor of PT usage intention. This factor proved that the decision to use PT is under the participant’s control.
Contributing to the main policy of PT in Northern Cyprus is another vital objective of the study. This paper brought forward problems and issues accompanying Northern Cyprus. It is easy to see that most of the questionnaire participants found the PT not at a good level. The main finding emphasises that the service should be planned to meet passengers’ expectations for the quality of service for attitude to have a positive impact on PT transport utilisation. In terms of urban transportation, the government usually tries to pursue policies that are geared towards minimising the usage of cars and promoting more environmentally friendly alternatives, such as PT. An easily accessible, high-quality public transit system is essential for sustainable transportation [
67]. Therefore, many people will accept a shift to PT if the PT system is improved in terms of safety, reliability, and availability with reasonable fees. It has always been the main policy goal of transportation authorities to explore ways to minimise the use of private vehicles and promote public transit. Dell’Olio et al. [
68] said that increasing PT usage is possible by reducing waiting times, offering better comfort while travelling, and describing information campaigns in their research area.
As a conclusion, good-quality, satisfactory, safe, comfortable, punctual PT with affordable prices must be provided by the authorities of the country. This will also change the attitude of the local public and contribute to the sustainability of cities by encouraging more passengers because PT is not sustainable now, according to the conducted study [
69].
