EVALUATION OF TRAFFIC MITIGATION MEASURES FOR TRAVEL TIME RELIABILITY (A CASE STUDY OF KEFFI - ABUJA ROAD)
Nigeria’s increasing population over the years coupled with diminishing resources has worsened its transport system especially in the Sub-Urban and Urban Centre like Abuja. As a result, the demand for transport far outstripped the supply and thus causing traffic congestion along the outer ring corridor of Abuja due to the absence of adequate mitigation measures. Thus indicating that the travel time would be unpredictable and the traffic service is less reliable. Supply side management measures are aimed at increasing the existing capacity of the system. The purpose of this paper is to identify the traffic influencing events causing congestion, determine the travel time reliability along Abuja – Keffi corridor and evaluate effective traffic-related measures in reducing congestion along this route. The process of traffic related measure was examined in this study and it was found that a measure related to bus stops provision is most effective in reducing congestion along this corridor. It is recommended that the Federal Capital Territory Administration (FCTA) should introduce bus stops at major and specified places with the intent of making the most safe and productive use of existing road. This measure is found to reduce travel time and is for relatively cheap and capable immediate implementation. The study will impact the community by changing the congestion profile as drivers adapt their departure time to the new travel condition.
