Evaluation of pedestrian crossing behavior and safety at uncontrolled mid-block crosswalks with different numbers of lanes in China.

•Pedestrian safety at uncontrolled mid-block crosswalks is closely related to the number of vehicle lanes.•Pedestrian behavioral characteristics have impact on pedestrian-vehicle conflicts.•The rolling gap crossing mode is the most dangerous way to cross the uncontrolled mid-block crosswalks.•Pedestrian-vehicle conflicts analysis model is proposed to analyze pedestrian safety considering the number of vehicle lanes.
