Investigate Attractiveness of Toll Roads

With the increasing congestion and pollution problems, tolling is becoming an intermediate reasonable solution to shift demands and divert traffic when building extra roads is not a viable alternative. There are multiple tolling strategies: fixed toll, toll rate by travel mileage, variable toll, high-occupancy-toll (charging solo drivers when they use a high occupancy vehicle [HOV] lane), etc. It is important to compare these different tolling plans beforehand, such that planning agencies will have an accurate prediction of traffic volumes, revenue, and cost of each individual tolling plan to make knowledgeable decisions on different alternatives. The factors that will have an impact on traffic volume diversion should be studied and the correlation among these factors need be modeled. The goal of this research is to develop a model to predict the percentage of traffic volume selecting toll roads over free roads in response to tolls to avoid congestion. The results of this research can be used to estimate the revenue and the resulting changes of traffic volumes on affected roads. At this stage, an initial literature review has been conducted to investigate the status of road pricing research. Current popular practice of tolling is to convert the HOV lanes to managed lanes where the HOV2+ or HOV3+ can use the lane for free while the other drivers need to pay. Due to the fact that different management agencies adopt different toll plans, the diversion traffic vary from one site to another. At sites where the HOV3+ vehicles are required to register their vehicles together with the information of carpooling persons, a decrease of HOV3+ usage of the managed lane was observed. The variation of practice policies adds complications to the study of diversion of traffic and requires a specific definition of the infrastructure of the manage lanes.
