Allocation of shared space

The demands and requirements for road space design, but also the space requirements of the individual modes of transport are currently undergoing a significant change. After years of focusing and orientation towards motor vehicle traffic, there is an increasing demand for a new division of road space. All road users are already considered equally in the planning processes, but especially in the road space division. Cycling and pedestrian traffic, in particular, are increasingly demanding a balance of usage claims. A new arrangement and design of elements such as lanes, side and recreation rooms including parking areas and charging infrastructure for cars, bicycles or even small electric vehicles as well as delivery areas for freight traffic are also sensible in terms of climate protection. Greening and shading not only serve to improve the microclimate, but also increase the quality and attractiveness of public spaces.  

But how are traffic flows and the demand for transport changing? Which spatial distribution makes sense in terms of the required capacities? How can shared space or meeting zones be implemented in the built environment? How can the road be redesigned as a living space? We address these and other questions in our research projects.

Our fields of action

  • Simulation and evaluation of road space design and road space use
  • Studies on demand developments, traffic volumes and capacity bottlenecks
  • Development of traffic forecasts and scenarios
  • Development of intermodal mobility concepts
  • Compile the requirements of different user groups

Our product portfolio supports you on this and many other topics.


Selected projects

A simulation of the planned redesign variants and the evaluation of their effects is helpful for the street space design and the repartition of the street space. Therefore, the research department participates in the EU-funded project MORE - Multimodal Optimisation of Road Space in Europe. This project aims to develop a procedure for the design of urban TEN-T corridors and to implement it in the cities of Budapest, Constanța, Lisbon, London and Malmö. The cities can use the interactions between different road users and dynamic solutions for road space design and evaluate implementation measures. Within the project the simulation software PTV Vissim is further developed to model a realistic representation of road space activities.

As part of FLOW - Furthering Less Congestion by Creating Opportunities for more Walking and Cycling, also an EU project, we have expanded our macroscopic and microscopic traffic planning software Visum and Vissim to better analyze the effects of measures to promote cycling and walking on congestion. An evaluation procedure for assessing the macroeconomic consequences of the measures for pedestrians and cyclists, taking into account multi-modal aspects, was developed. The CoEXist and ACCorD projects use our simulation software to investigate the lateral and longitudinal routing of autonomously moving vehicles and thus also permit an assessment of the dimensions of the traffic area and the capacities for which the future infrastructure must be designed.
