For the municipal authorities of The Hague, TNO Inro has made its generic travel time estimator for urban road networks applicable for two routes from the Utrechtse Baan to Scheveningen. This travel time estimator has been developed by TNO Inro in previous studies. Application of this travel time estimator to the mentioned routes required a number of extensions to the generic core of the algorithm. These extensions have to cope especially with the fact that both routes end in Scheveningen, with the use of a dynamic bus lane and with the estimation of travel times for routes which include public transport facilities like trams or buses. In this report, these extensions are described in detail. Because both routes end at parking garages in Scheveningen, the queues that may develop in front of these parking garages have to be estimated reliably. For that aim, additional queue detection loops have to be used. For the parts of the routes with a dynamic bus lane two separate modules will be developed, one module for the situation with active bus lane and one module for the situation without active bus lane. The routes including public transport facilities have been divided into separate components. When possible, the travel time for a component is estimated dynamically. For part of the components the travel time has to be estimated statically, for example with the aid of a time table. This is currently the case for the public transport facilities. Besides these extensions to the generic algorithm, an example of a control scenario has been worked out. This example makes clear how the travel time estimator can be used in practice by the city of The Hague. With the mentioned extensions to the generic algorithm, the algorithm can now be applied to each route in an urban road network, provided that the needed measurement data are available online.
