    This study appraised the state of urban transport in a Nigerian traditional city. It examined commuters’ socio-economic and transit characterization, assessed the quality of transport infrastructural facilities and services, and identified the challenges of urban transport services in Ibadan city, Nigeria. 163 copies of questionnaires were systematic randomly administered on commuters along six (6) selected traffic-corridors in Ibadan. Both descriptive and inferential (Binary Logistics Regression) statistics were used for data analysis. Major findings revealed majority (about 40%) of commuters were civil servants and earn above 90,000 naira as monthly income. Mean Weighted Value results show that taxi (3.913) and motorcycle (3.756) are dominant and most patronized means. Similarly, the availability (4.075), safety (4.000) and affordability (3.625) were most-weighted factors influencing commuting modal choice, while a trip to work (3.718) and market (3.200) are most generated trips in Ibadan. Meanwhile, most of the assessed infrastructural facilities were of poor quality, while peak/off-peak transit issues (4.050) and vehicular mechanical failure (3.487) were major challenges affecting urban commuting. Binary logistics regression results show that the condition of urban transport infrastructural facilities significantly influence overall satisfaction with urban commuting (p < 0.000). Cox & Snell's R-Square (36%) and Nagelkerke’s R (70%) show that the model is relevant in predicting the relationship between dependent and independent variables. The study concluded that there is a need to improve urban transport system towards ensuring commuters satisfaction and urban development. Hence, recommended among others, integrated transport system with smart devices and improved conventional public transport scheme in Ibadan.

    Traffic Congestion and Intelligent Transport System in a Fast-growing Nigeria City
    (University of Zilina, 2020) Salisu, Umar Obafemi; Akanmu, Ayobami Ademola; Fasina, Simeon Oluwagbenga; Sanni, Sekinat Motunrayo
    The dismal performance of the traditional traffic congestion measures and motorist attitudes on Nigeria roads have not only made traffic flow unpredictable and worsening but also worrisome and defiling every measures put-in-place by the Government. To solve these problems, the study assessed traffic congestion and Intelligent Transport System (ITS) in Ibadan, Nigeria. In achieving this, the study examined among others, factors aiding traffic congestion; effectiveness of the existing traffic congestion measures; and the performance and disposition to the use of ITS in the study area. Systematic random sampling was used to administer 386 copies of a questionnaire on commercial motorists, while data collected were analyzed using both descriptive and inferential (Pearson Chi-Square and Fisher’s Exact Tests) statistics. Findings revealed that faulty intersections (3.586) and excesses of traffic officers (3.558) were worsening factors aiding traffic congestion in Ibadan city. Meanwhile, electronic traffic signalization (3.558) and law enforcement and regulation (3.499) were rated the most effective existing traffic congestion measures. In other words, real-time traffic signal devices (3.609); automated travel advisory system (3.595) and road congestion pricing devices (3.581) were highly rated and favourably disposed to use ITS. However, the Chi-Square Tests shows that the use Intelligent Transport System is statistically influenced by users' level of education (Sig. value < 0.05). The study concludes that there is a total necessity and willingness to use ITS in the study area. Hence, the study recommends exigent and holistic approach in the provision and enforcement of ITS towards mitigating congestion and other suggestions for improved traffic flow in Nigerian cities including Ibadan
