Analysis on Congestion Level of Two Roundabouts
Urban road network is deteriorated in congestion at transportation and to mitigate the congestion conditions. It needs management and implementation for the lane management and highway design at the study area. Commuters are facing with congestion impacts such as spending extra travel time, fuel wasting and crashes for traffic queuing. This study is to analyze the congestion level of two roundabouts and signalized intersection. Traffic data were collected by video and manual record and speed data are counted by hand-held GPS. Traffic congestion level is evaluated NCHRP-572 for roundabouts, HCM-2010 guideline for signalized intersections and VISSIM simulation for proposed improvement. This study analyzes to mitigate the conversion of roundabouts to simple signalized intersections, retiming the existing signalized intersection and modification of lane configuration. It is expected that simulation of signalized intersection from roundabouts is obviously changed the nature of traffic flow and the link also reduces congestion in scenario.
