Background & Policy context

In densely populated areas, but increasingly also in suburban areas, mixed traffic arrangements are be discussed and implemented. The argument in favour of such traffic arrangements, as supplied by traffic planners, includes amongst others – from a point of view of the traffic as a whole system – the reduced need of space and the best possible use of infrastructure and also a better harmony between traffic management and the surrounding lived-in areas (lower speed level, considerations related to urban planning). With a view to the present study, mixed traffic shall be looked at from an overall and overriding view and the focus shall be placed on conflicts between road-users and on solutions to solve them, including every possible kind of mixed traffic areas and the use of adjacent space. With a view to existing conflicts, existing mixed traffic areas will hereby have to be analysed from all the different perspectives that may seem useful (traffic users, authorities, and so on).


The aim of the project is to unite results and experience gained from mixed traffic areas that have been implemented, in order to let them be part of future planning and to create a commonly accepted understanding of the expression of ‘mixed traffic’.


Based on the results of the literature review as to the practical experi-ments both of the research team as the advisory group, is a systematic approach to conflict analysis are developed. It is primarily a question of what aspects and desires of the groups involved are drawn and how they can be used specifically for the evaluation of a project with mixed use of the transport space.
We assume that we put together from the perspective of each group potentially involved a number of criteria that allow at least a qualitative assessment of a project or an existing situation. Since these criteria are partly general-my nature, partly but also turn to certain other road users, can thus be put together for each case of mixed traffic uses criteria lists. It also includes aspects of road safety or the severity of the conflict must be considered.
As part of the identification of conflicts must also be taken into account whether the conflicts in the field provided or "provoked" mixed traffic areas occur.

Result is a list of items per mixed traffic case, their impact can be described on the action. On the basis these results can be described subsequently, the pros and cons in which mixed traffic case can be found under what conditions and how to respond. These results are in recommendations for practice, especially for road safety work, for planning but also in legal respects. In a last step are special problems that arise or which are already known today deepened edited. Provided are now: Legal possibilities for real mixed traffic, relationships with existing elements of "pseudo-separation", solutions for road crossings of foot traffic.

Policy implications

Careful analysis and differentiated approach gives a comprehensive overview of fueling conflict or relevant factors. The pros and cons as well as the influence created a foundation which is both in planning practice, but also in general is evidence of traffic safety-related aspects of the practical implementation and especially the police application. In particular, the reclaimed legal relationships can help to clarify the options.
