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.

    The new release of PTV’s transport planning software, PTV Visum 15, is said to set new standards in multimodality and allow even more sustainable transport planning. New functions available in the software include the ability to analyse the demand, quantity and placement of park and ride (P+R) sites, enabling users to evaluate existing and future capacities. To allow users to model cycle and vehicle route-planning, PTV has enhanced the stochastic assignment so that path-level impedance elements can now be r

    The German AKTIV project is researching several cooperative driving applications for use in work zones. PTV's Michael Ortgiese details progress. The steep increases in traffic volumes predicted back in the early 1990s have unfortunately been proven to be more than accurate. In Germany, the AKTIV project continues to look into cooperative technologies' potential to reduce the impact of those increased traffic volumes and keep traffic moving despite limitations in infrastructure capacity.

    Perceptions of machine vision being an expensive solution are being challenged by developments in both core technologies and ancillaries. Here, Jason Barnes and David Crawford look at the latest developments in the sector. A notable aspect of machine vision is the flexibility it offers in terms of how and how much data is passed around a network. With smart cameras, processing capabilities at the front end mean that only that which is valid need be communicated back to a central processor of any descripti

    For some, machine vision is the coming technology. For others, it’s already here. Although it remains a relative newcomer to the ITS sector, its effects look set to be profound and far-reaching. Encapsulating in just a few short words the distinguishing features of complex technologies and their operating concepts can sometimes be difficult. Often, it is the most subtle of nuances which are both the most important and yet also the most easily lost. Happily, in the case of machine vision this isn’t the case:
