    Abstract
  • Based on the ability of processing information within the dynamic sights and visual fields of drivers, a calculation model of speed-limit value for traffic accident scene section was set up. According to the information characteristics of road and environment, traffic flow, traffic management, drivers, irrelevant personnel and weather, the occurrence probabilities of different informations were quantitated by using ergonomics theory. The speed-limit values were calculated in typical freeway accident scenes referring to the information characteristics. Calculation result shows that the speed-limit value is 70 km·h-1 in one-lane enclosed accident scene of bidirectional four-lane freeway. In one-lane and two-lane enclosed accident scenes of bidirectional six-lane freeway, the values are 80, 60 km·h-1 respectively. In one-lane, two-lane and three-lane enclosed accident scenes of bidirectional eight-lane freeway, the values are 80, 70 and 60 km·h-1 respectively.
