Abstract:
Currently used traffic control measures, such as traffic signals,
variable speed limits, ramp metering installations etc., are often not
designed to influence the route choice of drivers. However, traffic
control measures do influence the travel times that are experienced in
the network. Since route choice is, at least for a part, based on
experienced travel times, the control measures thus also influence the
long-term route choice. This influence can be seen as a side-effect of
the control measures, but in this paper we will investigate the
possibilities to explicitly and actively use the influence of the
traffic control measures to change the long-term route choice. Using
basic traffic flow and route choice models we investigate how outflow
and speed limit control can affect the final equilibrium turning
fractions. As an example we consider a case study for a simple network
with two routes and use a simple linear outflow controller, which
makes the analytical investigation of the effects of the controller
possible, but the results can be extended to more sophisticated
control methods.
