Quantifying the Mobility Benefits of Winter Road Maintenance -- A Simulation-Based Analysis

摘要: A good understanding of the relationship between highway performance, such as crash rates and travel delays, winter road maintenance activities under different weather traffic conditions is essential to development cost-effective policies standards, operation strategies technologies. This research specifically concerned about mobility benefit maintenance. microscopic simulation model used investigate patterns adverse surface conditions. segment Queen Elizabeth Way (QEW) located in Great Toronto Area, Ontario study. Observed field data from study was calibration model. Different scenarios characteristics a result events operations are simulated time performance measure for effect snow storms on section. The modeling results indicate that aimed at achieving bare pavement during heavy snowfall could reduce total delay by 5 36 percent, depending level demand highway.
