ASSESSMENT OF DIFFERENT TRAFFIC MANAGEMENT SCENARIOS USING MICROSCOPIC SIMULATION: A CASE STUDY
This paper presents the results obtained from microscopic traffic simulation study conducted to evaluate different traffic management scenarios (alternatives) for congested links in the capital city of Sana'a. The main objective of implementing simulation technique is to assist decision makers to select the most suitable solution to manage the problem of traffic congestion in effective and scientific manner and less cost for one of the busiest roads in the capital city of Sana’a. Different real-life implementations of four types of traffic management scenarios were carried out. This includes Do Nothing, convert curb parking lane to effective traffic lane, waving/shifting public traffic vehicles (microbuses) to other routs outside the studied road and redesign the traffic signals. The Do Nothing scenario was considered as control/reference scenario. The improving or worsening due to implementation different scenarios was measured by comparing results from studied scenarios to that of the reference scenario. Results were extracted from the simulation output reports and the selection of the most suitable scenario was based on a set of quantitative evaluation criteria. This includes delay time, travel time, flow, speed and fuel consumption. Based on the criteria used the succeed scenario was recommended for implementation. The scenarios being most effective were converting the curb parking lane to effective traffic lane and shifting public microbuses to other routs. Although there is no significant difference between these two scenarios, the first one was recommended due to its simplicity, lower cost of implementation and convenience to road users.
