    Ameliorating urban traffic congestion for sustainable transportation
    (IOP Publishing, 2020) Busari, A. A.; Loto, R. T.; Ajayi, S. O.; Odunlami, O.; Akintayo, F. O.; Oyesomi, K.; Olawuyi, O.
    Population, ownership of vehicles and economic growth are increasing at a geometric rate. Invariably, this will lead to an increase in traffic volume and the demand for limited road infrastructures. These has generated a lot of constraint on the few available road infrastructures in most developed and developing nations of the world. One of the consequences of this, is traffic congestion. This arises when the road system approaches vehicle capacity. Although governments and policy makers may never be able to eliminate road congestion, there are several ways cities and states can move to curb it. Hence, this review of literature assessed the myriad effect of traffic congestion, with focus on the economic and environmental impact. Additionally, long- and short-term measures to reduce the menace in 2030 were evaluated. This was done by assessing the relevant literature on the topic. The outcome of the review revealed that increase in income and living standard favours the ownership of automobiles thereby increasing traffic congestion. Households that reside in areas with compact, mixed land use own fewer vehicles, make fewer vehicle trips, therefore mixed land use should be encouraged in urban development. Additionally, level of Service (LOS) is another factor that affects traffic congestion and traffic crashes. The outcome of this review will aid the government and policy makers on the appropriate tool to adopt and the draw backs in a bid to reduce this menace now and in the foreseeable future

    Traffic analysis at a multileged intersection in Osun State, Nigeria
    (Faculty of Engineering and Environmental Sciences, Osun State University., 2019) Olawuyi, O. A.; Busari, A; Akintayo, F. O; Olagbule, T. E
    Transportation system plays an important role in modern life throughout the universe; however, the undesirable myriad of traffic congestion has caused a number of problems in the society. This study aimed at evaluating the flow of traffic at Okefia intersection in Osun State. The present level of service was obtained to evaluate the road capacity. The traffic volume survey of the intersection was done using manual count procedure, volumes were taken at peak period of the day for 7 days at each approach, the peak hour factor was used to obtain the level of service. Approaches A and B were dual carriage with lane width of 7.3m each at both bound separated by a kerb, approaches C, D and E are single carriageways with road widths of 7.3m, 6.5m and 5.5 respectively. The average traffic volume counts for the 7 days at peak hour was 2632,2517, 625, 3197 and 1694 veh/hr for approaches A, B, C, D, and E respectively. Therefore, the average peak hour factor at the intersection is 0.83 and this corresponds to an overall level of service (LOS) C. This LOS implied that there will be delay between 15.1 and 25.0 seconds per vehicle and thus witnessed longer cycle lengths and fair progression. In order to reduce congestion and to improve the road capacity there is need to build good parking facility and introduce traffic control system.
