The proposed work builds upon
projects: "Evaluation Study of the Port Authority of New York
and New Jersey's Time of Day Pricing Initiative"
et al., 2005a); the "Evaluation
Study of the New Jersey Turnpike Pricing Initiative" (Ozbay
et al., 2005) the NYSDOT's "Potential for Off-Peak
Deliveries to Congested Urban Areas" project
et al., 2005b; Holguin-Veras,
2006); and the "Advanced Travelers Information
System." Although they are discussed in "Related
Proposals," it is important to summarize key findings because
they provide the scientific support for the proposal.
The PANYNJ project conducted the evaluation of the impacts of the 2001 toll increases at the PANYNJ facilities on the behavior of both passengers and freight. The data gathered about the behavioral impacts on freight are the only data available in the world about this important subject. The research highlighted that freight pricing, in isolation of other policies, is of limited effectiveness in moving truck traffic to the off-hours. This is because the price signal reaching receivers is of no significance when compared to the marginal costs of moving to the off-hours. Since receivers are the carriers' customers, it is impossible for the carriers to switch to the off-hours without receivers willing to accept deliveries beyond their regular hours.
The project team members also conducted the "Advanced Travelers Information System." As part of the project, a fleet of 200 vehicles became GPS-equipped probes and shared wireless data about network travel times. This project was the first ever in the world for real time data to be collected by vehicles and then distributed back to those same vehicles, so that better paths could be selected. Because of its importance, an entire session of the 2005 TRB Annual Meeting focused on this project.
