Methods for predicting the flow of vehicular traffic have been studied in order to anticipate short-term changes in service level. However, if the target route is an expressway with capacity bottlenecks (e.g., sag sections), it can be difficult to predict when a breakdown in the traffic flow will occur. There is a need to model the traffic dynamics from the free-flowing state to a congested state...
This paper is focused on an application and evaluation of a lane use balancing measure with the variable message signs (VMS) installed on both sides of a carriageway in a bottleneck of a 3-lane section in one direction on a motorway. This is achieved by providing keep-left related messages on the roadside VMS or on the VMS on both sides, and on the entrance ramp to persuade drivers to use the left...
This paper examines the effects produced by connecting and changing the line of auxiliary lanes on lane utilization, bottleneck capacity and mitigation of traffic congestion on the expressway. It was found that the longitudinal utilization of the auxiliary lane increased in the range of 2–9% after continuous connection compared to that before. The average breakdown flow at the inbound bottleneck increased...
