“…Safety benefits of VSL are well established in the literature (Hegyi et al, 2005;Allaby et al, 2007). This is apparently because of the strong relationship between vehicle speed and traffic safety.…”

“…However, there is a considerable discrepancy about the mobility benefits of VSL; even though there are a number of studies that demonstrated its advantages based on empirical and simulation based research. For instance, Hegyi et al (2005) employed second order macroscopic traffic flow model METANET to implement a MPC based VSL algorithm on a 12 km stretch of a hypothetical road network. They reported 21% reduction in total time spent (TTS) for the entire network.…”

Variable speed limits (VSL) is an emerging ITS tool, which can help to improve safety and efficiency of motorway systems through a better harmonization of traffic flow. It can reduce variation in speed of vehicles travelling along the controlled section. The implementation of VSL encourages a uniform driving behaviour and thus resulting in a better distribution of traffic over the motorway network, and better utilization of the road infrastructure. The primary objective of motorway traffic management is to improve mobility benefits of motorways under acceptable safety standards; this is also the main purpose of applying VSL. This paper reviews the existing VSL methods from view points of safety and mobility gains or losses due to VSL on motorway systems. A systematic review of the literature of empirical as well as simulation-based studies is presented.

Abstract-We propose an integrated approach for dynamic route guidance and ramp metering using Linear Quadratic Model Predictive Control (LQMPC). The main objective is to maximize the throughput of the network by guiding traffic flow towards to insufficiently utilized infrastructures. Due to the linear property of the LQMPC, it is fast enough for real-time online traffic control with a short control step (30 second for example). Simulation results from a case study demonstrate that the proposed traffic control approach has great potential to solve congestion when disturbances occur on freeways.
