Research Highlights

Application of Smart Phone Truck Data for Freight Performance Measures and Transportation Planning

Miguel Figliozzi
Freight data is usually incomplete, scarce, and expensive to collect due to carriers and shippers' privacy concerns and the enormous variety of supply chain types and decision makers. This project will study a new, inexpensive yet highly promising source of freight data that provides commercial vehicle origin-destination, space/time coordinates and trajectories. This new data can also be integrated into existing data sources to provide a wealth of information including commercial vehic... Read More

Value of Travel Time Reliability: Commuters' Route Choice Behavior and Study of Tradeoffs - Phase 2

Miguel Figliozzi
David Levinson , Kathleen Harder

The issue of travel time reliability is becoming more critical for the movement of people and freight. In order to examine issues related to the value of travel time reliability, we plan to test drivers' preferences for alternate commuter routes in a real world setting. The research participants will drive on three different routes in two cities: (1) primarily freeway, (2) primarily arterial roads, and (3) other streets. Freeways have a possible trade-off between high speeds and con... Read More
