Channelization at road exit based on link transmission model

In this paper,link transmission model(LTM) was applied to simulate traffic flow under various traffic demands,by which we can investigate the influence of the length of channelization area on the performance of traffic flow.An approach to calculate flow density anywhere of a link was proposed.A novel method was developed to calculate congestion delay,which is beneficial to evaluate the performance of traffic flow.Numerical examples show that the level and the uniformity of traffic demand are the key factors that impact the length setting of channelization area.In addition,the length setting of channelization area under signal control was discussed.
