TRL launches SafeNET 2 - a new version of the Road Accident Prediction Software

摘要

October 12 2005 saw the launch of TRL's SafeNET 2 (Software for Accident Frequency Estimation for Networks), which predicts the number of personal injury accidents per year on a road network based on the traffic management, traffic flows and road layout. Or Alice Crossley and Dr Janet Kennedy, TRL, report on this empirical approach to road accident prediction. SafeNET 2 is designed to assist transport planners, road safety auditors and traffic engineers in the design, management and planning of safe road networks. Its accident prediction models are based on statistical analysis of data from the UK road network relating personal injury accidents to traffic flow, road layout and signal control variables. SafeNET 2 now offers a comprehensive set of rural accident prediction models in addition to the original urban models. It has an improved user interface and integration with traffic assignment models such as SATURN and CON-TRAM, a new improved NETBUILDER graphical interface which allows users to build their road network, as well as an enhanced graphical output.
