Impacts of Rain and Waterlogging on Traffic Speed and Volume on Urban Roads

摘要

to -24.3%, -25.8% to -31.2% respectively) is generally greater than rain (-1.2% to -18.4%, -1.1% to -16.5% respectively). It is also found that reductions in volume during the off-peak period are generally greater than those during peak hours however an opposite pattern is observed for speed. This research provides the intelligent transportation system with detailed information which is helpful for early warning, risk management and weather-responsive transportation management strategies devisal under rainy and waterlogging conditions. Further research might focus on the connections between research findings and their applications in the ITS context.
