COLOMBO Deliverable 5.3: Traffic Light Algorithm Evaluation System

Abstract

Deliverable 5.3 describes the work performed in Task 5.3 on a “Traffic Light Algorithm Evaluation System”. This work includes two approaches. The first is the derivation of a single performance indicator that combines conventional traffic efficiency measures, measures describing how drivers perceive the traffic state as well as environmental measures. The work is accompanied by a summary on nowadays benchmarking of traffic lights. The developed performance indicator may be used for both, benchmarking new developed traffic light algorithms as well benchmarking real-world traffic lights. The second approach is the definition of a suite of tests where each test investigates the response of a traffic light algorithm under evaluation when being posed against a certain traffic characteristic. To determine which traffic characteristics should be covered and how they occur in reality, real-world data evaluations have been performed. In subsequent steps, the evaluation system itself is presented, including the requirements put on it, its software realisation and user interaction, as well as the scenario sets that respectively cover a certain traffic characteristic. Both approaches are joined by proper interfaces.
