Expert Support for Traffic Safety Work
Introduction
Evaluation and further development of Infrastructure Safety Instruments (ISSI). Within the framework of Via sicura, the action program for increased road safety in Switzerland, the parliament established requirements for safe road infrastructure in the Road Traffic Act. The Swiss Federal Roads Office (ASTRA) developed six Infrastructure Safety Instruments (ISSI) to support authorities at the federal, cantonal, and municipal levels. PTV Transport Consult has been advising ASTRA from the very beginning as part of professional support.
Project Description
By providing implementation guides (manuals Link / Link) for decision-makers, the aim was to familiarize stakeholders with the ISSI procedures, increase acceptance, and provide guidance for practical application. Selected ISSI were evaluated in pilot applications regarding their feasibility, comprehensibility, and usefulness. In addition to methodological, statistical, and engineering fundamentals, aspects such as clarity, quality assurance, organization, internal and external communication of results, and implementation in tools are also considered. Supplementary tasks include in-depth accident analyses, the execution of Network Safety Managements for national roads, derivation of indicators and threshold values, updating the training concept, and professional support for the annual exchange platform for safety officers.
The goal of the technical support is to promote widespread acceptance and implementation of road infrastructure safety management at all levels of road ownership in Switzerland.
