Assessing the Impacts of Real-Time GPS Navigation Applications on Trip Routing and Diversion Rates
Publication: International Conference on Transportation and Development 2024
ABSTRACT
Smartphone navigation applications and in-vehicle navigation technologies provide drivers with real-time traffic conditions and route guidance among other numerous benefits. These technologies promise transformative improvement in daily commutes and prevent the possible increase in traffic delays and congestion. The limits of such benefits are dependent on the frequency of using the navigation applications, diversion rates, and the percentage compliance with the suggested re-routing. Commuters in Broward County, southeastern Florida, were surveyed to understand their preferences and the factors affecting route choice decisions. A multiple linear regression model was used to predict actual traffic diversion rates and to validate the survey results. Major findings of this research included a variety of characteristics associated with navigation applications, drivers’ behavior, and roadway facility usage. In general, navigation applications have a significant re-routing potential, and drivers are likely to divert 20% to 39% of the time. It was found that most drivers would consider a re-routing suggestion when the delay per 1-h trip is approximately 15−30 min. Finally, the results were consistent with the regression model and showed that the actual diversion rate ranged from 1% to 20%.
