Abstract:

The shareduse paths used by pedestrians, cycles and electric bicycles without physical separation or height difference was studied. Firstly, a basic cycle traffic conflict model was put forward to describe cycle passing and meeting events. Secondly, some special data collection methods were designed for the object of study, and five typical trails of slowmoving traffic were selected to perform the investigation in Nanjing city in China. Thirdly, electric bicyclescycle passing conflict model, cyclecycle passing conflict model, cyclepedestrian passing conflict model and cyclepedestrian meeting conflict model were set up respectively according to data collected. Finally, an intensity conflict model was built considering the effect of shareduse paths' width. The results of sensitivity analysis show that the value of all types of traffic intensity conflicts decreased with the increment of path's width, while cyclepedestrian passing and meeting intensity conflict contributed much more to the total impact than bicyclescycle passing intensity conflict and cyclecycle passing intensity conflict in shareduse paths.
