1. INTRODUCTION Road transport forms part in the day to day activities for most individuals and in Ghana it is the principal mode of transport. A modern transport system which provides high quality of services has been a topical issue in transport modelling literature (Cullinane, 2002; Ebuli and Mazzula, 2007; Ali, 2010; dell'Olio et. al., 2010; Randheer et al. 2011). According to Ali (2010), transport is important for the survival of the modern society. An effective and efficient system of transport can significantly contribute to human development in a wider perspective. Urban cities in Ghana increasingly face problems caused by road transport externalities. For example, there is an increasing trend in road traffic crashes, traffic congestion and emission of carbon dioxide. The impact from road traffic congestion, carbon emission and road crashes is significant in time, pollution and economic loses. Part of these problems is as a result of greater number of low occupancy commercial as well as privately owned vehicles in the cities. According to dell'Olio et. al. (2010), an important characteristic of modern society is its preoccupation with promoting sustainable modes of transport to replace the excessive use of the private car in most urban areas. Despite the vital role that buses play in any urban areas, their services are frequently insufficient to meet demand and the services that are provided mostly suffer from low output (Ali, 2010). In many parts of the world, individuals tend to use their private vehicles due to lack of satisfaction they derive from the services of public transport. For instance, the findings of Cullinane (1992) in an attitudinal survey in UK showed that 41% of private car users would reduce their car usage if public transport became frequently available and reliable. Again, Cullinane (2002) used attitudinal survey based on sampled university students in Hong Kong and found that good public transport can deter car ownership, with 65% of the respondents in the survey stating their unlikelihood of buying a car in the next five years. Improvement in transport system can have a positive effect on land development (Deng and Nelson, 2010). Deng and Nelson further describe that high quality of public transport system can greatly improve the accessibility of its catchment area by shortening time. Ebuli and Mazzula (2007) also comment that an improvement in the supplied service quality can attract further users. Randheer et al. (2011) argue that, in the current scenario of globalization, public transport service needs introspective sensitivity towards the quality of service offered. Transportation system can be a reliable indicator of economic development. It works as a factor that stimulates economic growth by providing employment, improving the effectiveness and efficiency of other businesses and also contributing to national investment and development. According to Dube et al. (2011), public transport plays a social role in the urban environment: it improves access to work places and service infrastructure and at the same time, reduces travel expenses. Both public authorities and transport operators are involved in policy formulation and implementation in relation to transport services. Since public authorities and transport operators have different goals, regulation plays an important role, especially, failing competition (Gatta and Marcucci, 2007). Passengers satisfaction relating to transportation has been studied in many countries. For instance, Friman (2010) examined affective reactions to passenger waiting times relating to public transport and their impact on overall satisfaction with the service in Sweden. Using Analysis of Variance (ANOVA) technique, the study found that overall satisfaction with public transport corresponded with the nature of the waiting time scenario. Chen and Lai (2011) explored the relationships between passenger's behavioral intentions of public transit and the various factors that affect service quality, perceived value, satisfaction and involvement in Taiwan. …
