Abstract Few research studied the effects of short-term and long-term driving restriction policy. Aiming to this gap, Tianjin City, China was taken as an empirical example to evaluate the effects of the two policies in this study. First, traffic survey of several segments and intersections was conducted to compare their traffic volume before and after the implementation of driving restriction policy. Then, a revealed preference-based survey was conducted to evaluate the policy effects. The case study indicates that the long-term driving restriction policy has transferred massive passenger flow into the public transport system, but it is only effective to reduce traffic volume in short-term; some traffic flow transfers to the weekends and the hour preceding the restriction time; rule-breaking behavior is pervasive for the short-term driving restriction policy; and the short-term earns high marks than the long-term policy. Additionally, some countermeasures were provided to improve the effects of the driving restriction policy.
