Traffic Flow Model Modification on Ice Condition of Road

Article Preview

Abstract:

The paper analysis the influence of ice snow on flow at the view of the driver and the car, and through measuring a certain road in Heilongjiang province, getting three parameters of flow, speed and density of early high peak period of the ice snow road and normal road. The data that passes the actual diagraph builds up the transportation to three parameters of flow speed-density model, taking this model as the foundation, deducing a speed-density model. Pass the method that begs the pole value to the speed-discharge model, get to ice snow and no ice snow two kinds of appearances of the research road segment of go through the ability physically. Pass the research road segment the transportation environment and the road line forms of the place, established to affect the factor that that road goes through the ability physically and it to should of coefficient, thus build up the influence factor model that rises the calculation to go through the ability physically.
