Traffic Signal Design

3-4 September 2013

This course is designed for trainee traffic engineers or more senior and experienced engineers requiring a refresher on current industry practice. It is in accordance with the Hong Kong Transport Planning Design Manual (TPDM) and international best practice. The course will probe the following issues:

  • Choice of junction layout – why traffic signals?
  • Designing for all road users, including pedestrians
  • Traffic signal layout
  • Traffic signal method of control
  • Capacity calculations, manual and computerised
  • Drawing production
  • High level introduction to traffic modelling
  • Area traffic control basics
  • Legal requirements
  • Technology

A site visit will be included to explain basic terms. Attendees would have the opportunity to undertake a complete manual calculation of an example traffic signal junction including working out of signal timings and capacity according to Webster and Cobbe.
