Effects of HOV lanes on urban area in China

Abstract

This study developed a VISSIM-based traffic and emission modeling platform to assess HOV lane feasibility in Hangzhou’s urban area. Realistic simulations considered lane configurations, vehicle compositions, and driver behavior.

Results show HOV lanes positively impact emission reduction when single-occupancy vehicles to multi-occupancy vehicles ratio is below 17:83. However, the relationship between HOV lane increase and emissions is not linearly positive, varying with vehicle composition. Adding HOV lanes is an effective policy to enhance market penetration and local air quality. These findings provide a foundation for decision-making and comparisons with similar Chinese cities.

Implementation of HOV lanes in Hangzhou could set a precedent for sustainable urban mobility nationwide.
