Analyzing Mobility Benefits of Variable Speed Limits Motorways

The performance of three variable speed limit (VSL) control algorithms; a flow-based, an occupancy based and a logic tree based algorithm for a critical bottleneck section of the Auckland Motorway are assessed in this paper using Aimsum micro-simulation. The paper presents four main conclusions. The first conclusion shows that VSL is an effective intelligent transportation system (ITS) measure that produces mobility benefits and emissions reductions. The second conclusion shows that the VSL performance is dependent on the control logic and driver compliance levels. The third conclusion shows that VSL has the potential for improving and managing recurrent congestion on motorways. The fourth conclusion shows that the mobility benefits of VSL is at its best when there is 100% driver compliance. The paper shows that travel time savings will increase with driver compliance.
