A generic approach to generating optimal controlled prespective route guidance in realistic traffic networks
conference paper
This paper presents a generic methodology to generate optimal controlled dynamic prescriptive route guidance to be
disseminated by means of variable message signs (VMS). The methodology is generic in the sense it can be used on
any network topology and network model, with any number of VMS’s, for different traffic scenarios (e.g. recurrent
congestion, accidents, or special events), based on a flexible user defined objective function and will work as long as
feasible route alternatives exist.
The presented methodology calculates prescriptive VMS settings with the objective to minimize the total
generalized travel time. An evolutionary algorithm is used to generate and optimize VMS-scenario’s. A new traffic
model, DSMART, has been developed to assess the quality of the route guidance.
A prototype of the guidance system has been developed in Matlab and applied in a case study to the city of
Rotterdam in The Netherlands by using a network representation of the motorway with six different VMS’s and the
connected urban network. The results from the case study prove the generic nature of the methodology and its ability
to improve overall network conditions for various traffic scenarios
