Query: A microsimulation approach for the impact assessment of a
  Vehicle-to-Infrastructure based Road Hazard Warning system   Cooperative Intelligent Transportation Systems (C-ITS) constitute
technologies which enable vehicles to communicate with each other and with road
infrastructure. Verification or testing is required for C-ITS applications, in
order to assess their impact on traffic operation. In this work, a microscopic
traffic simulation approach is used, to evaluate the impact of
Vehicle-to-Infrastructure (V2I) technologies in the context of a road traffic
accident. Specifically, the methodology is implemented to explicitly models
vehicles collisions, Road Hazard Warning (RHW), Emergency Electronic Brake
Light (EEBL) warnings and the resulting driver behavior. Moreover, a new gap
control mechanism is adopted, to improve safety by advising vehicles in hazard
lane to increase their headways with respect to their preceding vehicle, so
that they can avoid a collision. Perfect communication links to all vehicles
are assumed. The study findings indicate that the proposed V2I hazard warning
strategy has a positive impact on traffic flow safety and efficiency.
