Abstract
The traffic volumes of trucks on freeways and parallel national and provincial roads significantly vary; moreover, the utilization rate of freeways is markedly low at times. Implementing effective traffic volume guidance to change the travel route choice intentions of truckers is a critical approach to improving the utilization rate of freeways. Travel route choice intentions are influenced by numerous factors, such as personal and travel characteristics. In this study, based on structural equation modeling (SEM), 186 truckers on freeways and 522 truckers on parallel national and provincial roads were collected using structural equation modeling (SEM) based on a questionnaire survey in Guangxi, China. Relationship models of the influencing factors of travel route choice intentions for truckers on freeways and on their parallel roads are constructed separately by SEM to explore the direct and indirect effects of the personal characteristics, travel characteristics, economic factors, and travel choice habits of truckers on travel route choice intentions. The model results for truckers on freeways indicate that only travel characteristics significantly affected travel route choice intentions, and this effect was negative. For truckers on parallel national and provincial roads, travel characteristics exerted the most significant positive effect on travel route choice intention; by contrast, travel route choice intention was most negatively affected by economic factors. The results for the two models reveal that personal characteristics, and travel choice habits exert no significant effects on the travel route choice intentions of truckers on freeways and parallel roads. In addition, the results of the mediation analysis demonstrate that personal characteristics have a significant indirect effect on travel choice habits mediated by travel characteristics. Based on the study findings, several recommendations can be suggested as guidelines to facilitate the shifting of the traffic volume of trucks.
