Abstract: Setting variable lane could make full use of existing road resources and effectively relieve urban roads tidal traffic problems during peak hours. Firstly, the basic conditions of setting variable lane were analyzed from road condition and traffic flow characteristics. Secondly, a model to evaluate the road traffic capacity efficiency was established by the entropy method. Thirdly, the relationship between traffic flow and running speed was discussed combining with the road capacity model. Fourthly, the effect evaluation method and calculation method of setting variable lane was put forward. Finally, taking the roads in one city as an instance, the application research of the proposed evaluation method was carried out and simulation analysis was carried out by traffic simulation software Vissim. The research results show that the proposed method is feasible.

Key words: traffic engineering;variable lane, running speed, capacity, travel entropy method
