Materials developed by K. Watkins, J. LaMondia and C. Brakewood Comparing Transit Modes Unit 1: Introduction
2
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Outline Transit mode definition. Families of transit modes. Comparison of modes and mode selection in the US.
3
Materials developed by K. Watkins, J. LaMondia and C. Brakewood TRANSIT MODE DEFINITION First, let’s define the transit we’re working with
4
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Transit Mode Definition 4 Basic Characteristics: Right-of-Way (ROW) System Technology Types of Service Organizational Oversight
5
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Characteristic 1: Right-of-way ROW C Mixed Traffic ROW B Physically Separated ROW A Fully controlled Street TransitSemi-rapid TransitRapid Transit Speed of Vehicles Operating & Capital Costs
6
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Examples of ROW Classes Class A: Boston Red Line Class B: Dublin Light Rail Class C: MARTA Bus
7
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Pros and Cons of Rights of Way ROW B ROW A ROW C + Higher performance – speed, reliability, capacity, comfort, safety + Use of longer vehicles + Stronger identity / image + Lower per passenger operating cost + Can be electrified - Require space for ROW - Higher investment - Special signals or control / priority measures + Highest performance + Electric guided technology + High safety + Short dwell time - Highest investment cost - Rigid alignment - Grade-separated stations require land and longer access

39
Materials developed by K. Watkins, J. LaMondia and C. Brakewood New Diversity of Transit Modes More rail being constructed; since 1970: – 7 new heavy rail systems constructed (BART, WMATA, MARTA, Baltimore, Miami, LA, San Juan) – Nearly 20 cities opened or are constructing new LRT systems Resurgence in streetcars and tramways after decades of elimination Buses traditionally non-priority – Buses carry 60% of transit passenger trips – Mostly transit captive – BRT is changing this
40
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Mode Selection Systems Approach: Cities require multiple modes integrated and working together for the highest ridership Choice of modes depends on many factors, including life cycle costs, LOS, economy, impact on surrounding, passenger attraction and livability

42
Materials developed by K. Watkins, J. LaMondia and C. Brakewood Conclusions Understanding the differences in transit modes is critical Cities often require multiple modes integrated and working together for high ridership Make the mode fit the service instead of the service fit the mode – rest of course focuses on service
