This paper aims to compare the rear-end crash risk in work zone activity areas by using work zone traffic trajectory data collected from Singapore and Beijing, as well as analyze the differences of the traffic flow characteristics between the two cities. A surrogate safety measure, time-to-collision (TTC), is adapted to measure vehicle rear-end crash risk. Potential reasons for the differences in the work zone traffic safety in Beijing and Singapore are discussed based on the comparison. Some practical improvement plans, based on guidance from Singapore are then recommended for implementation in order to improve traffic safety in work zones in Beijing.
