Improved Monitoring of Traffic Signal Controls

From 2015 to 2016
The Flemish government wants to develop an instrument to monitor the performance of traffic signal controls in a reliable, objective and transparent manner.
The approach is to monitor the quality of the traffic signal controls by means of Key Performance Indicators (KPIs).
An important constraint is that the data collection for the calculation of these KPIs is done in a cost- and time-efficient way.
To this end, TML and its subcontractors Arcadis Belgium, Imtech, and Flow conducted a research project in which we developed a framework that describes such an instrument.

More specifically, we focused on the following research questions:
  • Which KPIs are most appropriate to determine whether traffic signals need maintenance?
  • How should these KPIs be defined and how should they be measured?
  • How should these KPIs be combined to develop a priority list of traffic signal controls that need maintenance?
TML developed and analysed the specifications for the KPIs, and established a roadmap to implement the monitoring and evaluation system for all 1600 traffic signal controls in Flanders.
