Abstract: Facing the challenges of road traffic safety management, the existing researches on traffic safety and risk analysis are mainly based on single factors, specific event settings and scenarios.There still lacks the proactive safety management oriented research in the whole network environment.Based on the clarification of the current regional safety characteristics and network management requirements, this paper puts forward a regional safety risk analysis framework containing three main processes, namely, risk identification, assessment and control, with respect to risk management.The key link and content of risk analysis and management under the regional network environment are defined and outlined.From the macroscopic policy, technology improvement and organization and coordination mechanism, this paper proposes a risk control strategy hierarchy including the control strategies at the macroscale, mesoscale and microscale levels respectively with the aim of reducing regional risk.It proves the possible transition from passive safety management to proactive management and provides technical measures for government safety management.
