SHARED-USE BUS PRIORITY LANES ON CITY STREETS: CASE STUDIES IN DESIGN AND MANAGEMENT

摘要

This paper examines the policies and strategies governing the design and, especially,operations of bus lanes in major congested urban centers. It focuses on bus lanes that operate inmixed traffic conditions; the study does not examine practices concerning bus priority lanes onurban highways or freeways. Three key questions addressed in the paper are:1. What is the physical design of the lanes?2. What is the scope of the priority use granted to buses? When is bus priority in effect, andwhat other users may share the lanes during these times?3. How are the lanes enforced?To answer these questions, the study developed detailed cases on the bus lane developmentand management strategies in seven cities that currently have shared-use bus priority lanes: LosAngeles, London, New York City, Paris, San Francisco, Seoul, and Sydney. Through the casestudies, the paper examines the range of practices in use, thus providing planners anddecisionmakers with an awareness of the wide variety of design and operational optionsavailable to them. In addition, the report highlights innovative practices that contribute to buslanes’ success, where the research findings make this possible.
