Performance Analysis of Continuous Flow Intersection in Mixed Traffic Condition
ACEE Int. J. on Transportation and Urban Development, (April 2012)
Abstract
The rapid increase in the volume of traffic in most of the countries is surpassing the threshold level of the present transportation system and demands a more efficient and intelligent system to be dealt with. As renovation of urban transport infrastructure is not feasible, there is an urgent need to find alternative solutions to the problem. One way is to devise methods for optimal utilization of available infrastructure (road space) in such a way that the carrying capacity of the roadway is enhanced and the conflict points reduced. This may be achieved by Continuous Flow Intersection (CFI) using pre signal concept which is an innovative traffic signal intersection. The principle behind this intersection is that the main conflicting traffic, i.e. the right-turning traffic is segregated from the main flow at the intersection. This study is concerned with evaluation of Continuous Flow Intersection (CFI) under heterogeneous traffic flow conditions using computer simulation. The analysis of the simulation results show that the CFI design is certainly more efficient when compared to conventional designs even in highly heterogeneous traffic conditions.
