The MODETRA project studied and developed a methodology for the design and implementation of traffic calming systems.
The project laid down a set of technical criteria on which a possible improvement of the proposed norms can be based. Thus, it was intended to systemise their use, optimising their effectiveness as traffic calmers, their economic impacts and their influence on traffic.
The characteristics of existing devices and their influence in the environment were studied by conducting a number of experimental tests. The tests were used to define the parameters to take into account for the possible homologation of normative of these kinds of devices and to write a document of general recommendations of the related installations (distance, signalling, geometries, combination of systems, etc.) both for urban arterial roads and for local streets.
The effectiveness of these recommendations has been evaluated through the practical application in a municipality and in a pilot study.
New systems of traffic moderation/calming were developed.
The results of the project provide a tool for different administration to introduce traffic calming measure more effectively, in a rational, secure and acceptable way by drivers and other road users.
