Sudden events can make great influence on road network's ordinary operation. Travel time is an important parameter evaluating the performance of road network. The paper analyzes relationship between travel time and traffic flow on a road section, analyzes distribution rule of traffic flow on each routes in a road network and travel time reliability. A nonlinear programming model in chance constrained is built according to these analyses. Test the model with an example indicates that the model can quantitatively analyze influence of route selection to travel time and travel time reliability under different traffic flow in sudden events. The model is beneficial to studying reliability of road network and dealing with sudden events.
