In order to accurately predict the traffic journey intensity of residents along the highway, according to the mechanisms of production of the traveling, analyze the influences of traffic journey intensity of residents from the three angles including residents' willingness to travel, destination’s attraction, traffic resistance, and predict the traveling intensity combined with the unconstrained gravity model. Then introduce the sensitivity of travel cost and analyze the impact of sensitivity of traveling cost on the traffic journey intensity. Finally, with an instance of the radiation areas of Zhaoma highway in Yunnan, calculate the calibration parameters in the unconstrained gravity model combined with the increase method and analyze the sensitivity of traveling cost within the scope of radiation areas. The results show that there is significant exponential relationship between the traffic journey intensity and the sensitivity, and it can provide some theoretical basis for the trip distribution; the gravity model is reliable and viable in some degree, and has a certain guiding significance for planning the road infrastructures.
