    Dynamic traffic management plays an essential role within the Dutch national traffic and transport policy. To continue the contribution to the implementation of this policy, it is necessary that the dynamic traffic management is further developed and implemented. A pro-active and network-wide approach to traffic management is envisaged to replace the more reactive and locally oriented approach cur... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (424 KB)

    Local vehicle actuated control is the most common form of traffic signal control in the Netherlands. An important parameter is the maximum green time. Currently, these parameters are fixed or are specified in a number of sets. In changing traffic conditions it is possible that the set of maximum green times is not fit to cope with these changing conditions. Therefore, methods were developed to dea... View full abstract»
