MOTION for SITRAFFIC - a modern approach to urban traffic control

Abstract

The paper describes SITRAFFIC and MOTION. SITRAFFIC is a modern advanced traffic management system for urban traffic control (UTC) and other applications. The traffic control concept is decentralized and hierarchical. MOTION forms the core online model of SITRAFFIC UTC; it optimizes the control variables of the traffic lights in the network. MOTION includes incident detection, automatic signal plan generation and advanced features for public transport prioritization. Some results of the different system evaluations are reported as well as aspects of recent installations in European cities.
