Abstract

Key messages:

• Urban Traffic Control systems (UTC) can be expected to improve network efficiency by reducing delays to vehicles. This can have additional benefits in reducing fuel use and emissions (although evidence here is limited).

• Economic benefits are calculated mainly on the basis of time savings. These savings may be specifically for public transport users, cyclists, or for general traffic

• Providing priority to public transport or bicycles through UTC can contribute to significant journey time savings without compromising journey times for other road users.

• Automatic systems to monitor bus lanes and signalized junctions have been shown to improve journey times, reduce infringements and reduce collision rates at junctions.

• Investment payback periods for bus priority measures are seen to range from 3 months to 2 years in the examples reviewed.

• Variable Message Signs (VMS) can divert some traffic (although they are less likely to be effective in heavily congested networks).

• VMS has the potential to contribute to time savings in public transport corridors, but evidence is currently limited here.
