According to the vehicles on the road affecting surrounding population and environment, this paper presented the most-hidden path and the most-popular path models, and provided the calculating methods of cost value and the solving process of the proposed two models. Combining with the road network of Wuhan City, several examples were carried out and the distance and the polulation number differnece of different road(including the most-shorest, the most-hidden and the most-popular paths) and difference cause were compared and discussed. The results show that these two models are reasonable and ...
