Network management and the forecast of accident blackspot locations

Traffic accidents are a well versed subject for traffic engineers in exploring issues of road design, control systems and feeding into the appraisal process. For many years teams have conducted road safety investigations to advise on the design considerations for improvements to road networks. This has been complemented by public strategies for blackspot management, safer roads, enforcement policies and changes in public behaviour. Many of these measures, in particular those of road safety reviews are often conducted retrospectively on historical accident datasets. Whilst this works well in many developed nations, road traffic injuries continue to become an increased cause of global burden. Road safety is becoming an increasingly significant component of the transportation planning process and requires smart solutions for management, design and planning prior to implementation. The PTV VISUM Safety platform addresses the three key tiers of road, infrastructure and safety management and has potential for intelligent traffic safety evaluation. Remedies identified from road safety assessments often clear traffic engineering defects by analysing the accidents and determining historic causes. However these measures anticipate the same trip-making patterns in order to designate a future benefit. By comparison, the PTV VISUM Safety offers an Accident Prediction Methodology (APM) that combines numerous elements including forecast traffic volume, road network design, control systems and accident frequency to determine the number of crashes in the future. This may be subject to new land uses or infrastructure, network management and route choices whereby accident forecasting is linked together to the demand forecasting. PTV presents recent applications of an Accident Prediction Model to determine future year accident estimates for a national network solution in Switzerland.
