ROAD INFRASTRUCTURE SAFETY MANAGEMENT www.ptvgroup.com Road Safety Analysis with PTV Visum Safety 2014-02-27 ROAD TRANSPORT IS VITAL TO DEVELOPMENT In facilitating the movement of people and goods, road transport improves access to education, health care, employment, and economic markets. It generates economic growth and employment. l t Unfortunately, in the absence of adeq ate attention to safety, adequate safet an emphasis on maximizing the efficiency of road transport systems has led to significant loss of lives lives, health and wealth.

The basic idea is combining different disciplines as transport t t planning, l i traffic t ffi engineering i i and d ttraffic ffi managementt for f increasing road safety or just better roads. The new approach wants to support road safety with: > Strong linkage to transportation planning and modelling Support of decision making process on strategic level > Integrative approach Combining different aspects and integration in a comprehensive safety management frame (closing the loop of optimization) > Interdisciplinary approach for road safety work Combining transportation planning, traffic engineering and traffic management in an integrative approach and common platform for collaboration on transport issues especially in terms of road safety. www.ptvgroup.com Page 19 ROAD SAFETY LINKED TO TRANSPORT PLANNING The following challenges have great potential to make road safety work more effective: Further investigation how road safety will benefit from additional data e e.g. g speed data data, road surface surface, etc etc. Evaluation on how the additional road safety information affects other disciplines like transport planning planning, traffic engineering and traffic management Evaluation Evaluation Risk Impact Assessment (RIA) use cases with Accident Prediction Models in several countries Stimulate road safetyy experience p exchange g based on assessment tools and best practice outcomes worldwide www.ptvgroup.com Page 20 YOUR CONTACT DATA FOR THE ROAD SAFETY Münch Andre Münch, Director Traffic Safety Traffic Software PTV GROUP Hoffmann Timo Hoffmann, Product Manager Safety Traffic Software PTV GROUP PTV AG Karlsruhe Haid u.
