3264 PTV Group has added mesoscopic simulation to its Vision Traffic Suite with PTV Vissim 8, which offers additional modelling level speeds up simulation by a factor of 50 compared to microscopic simulation.

According to PTV, users need to simulate increasingly large networks and PTV Vissim 8 responds to this trend by introducing dynamic assignment even in medium-sized networks, as mesoscopic simulation is ideal for achieving quick computing times. This allows users to see the effects of phenomena such as blocking back or traffic light signals on journey times without having to wait for their computer systems to keep pace.

Networks already created in PTV Visum can be easily transferred to PTV Vissim, where they can be simulated mesoscopically. If users need to go into detail on specific routes or junctions, this can be done via a hybrid simulation, which involves specifying sections of the mesoscopic simulation in which all modes of transport and their interactions - including pedestrians and cyclists - will be simulated at a microscopic level.

    Changing needs of mature and emerging economies are demanding more rigorous enforcement services. Gatso’s managing director Timo Gatsonides spells out the challenge to Jason Barnes. As geographical markets mature and saturate, it might seem that the only thing for suppliers to do is to look further afield in search of new opportunities. The automated enforcement market in north western Europe could be a case in point, but Gatso’s managing director Timo Gatsonides begs to differ. The sheer number of new syst

    Someone once likened predicting the future to ‘nailing a jelly to the wall’. With ITS, C-ITS and V2X technology progressing at such a pace, predicting the future is more akin to trying to nail three jellies to the wall – but only having one nail. And yet with roadways having a lifetime measured in decades, that is exactly what highway engineers and traffic planners are expected to do. Fortunately, New Hampshire DoT (NHDoT) believes its technological advances may be able to provide a solution. The Central Ne
