The late delivery of freight due to highway congestion and other factors increasingly affects private sector production, logistics, and shipping operations by increasing transportation costs.

A joint research team from CFIRE and the University Transportation Center for Mobility (UTCM) at Texas A&M University recently completed a CFIRE-funded project that focused on developing a model for estimating the value of delay (VOD) for highway freight shippers. CFIRE Director Teresa Adams and UTCM’s Dr. Bruce Wang served as primary investigators for this project.

Freight delay affects shippers in many ways, including their decisions about safety stock in inventory. For shippers operating a just-in-time system, freight delays cause losses in productivity and even losses in sales. Past studies have also considered the perceived value of time for commuters and commercial drivers, but little research has focused on the value of delay (VOD) from the perspective of shippers. The cost of freight delay is usually measured as a monetary value in U.S. dollars.

This project aimed to study how freight delay incurs costs to shippers and how these costs vary with the shippers operational characteristics. The research team used individual interviews, surveys, and an analytical study of inventory management.

The results of these analyses indicate that en route transportation delay is the most important component of delay, followed by delay at the item collection point. Delay at transfer points is not considered significant, perhaps because direct shipping bypasses distribution centers. Regression tests indicated a value of delay of $56 per hour when all participants are included. Researchers also obtained values of delay for nine industry groups, with two different demand and lead time patterns, and two different types of services.

Novel Bridge Abutments using CLSM

July 16, 2012

The construction of bridge abutments and their deep foundations is time-consuming and costly. This is one of the major obstacles that faces rapid bridge construction for typical span bridges used in railway and highway applications. Researchers at the University of Wisconsin-Milwaukee and the University of Wisconsin-Madison have recently completed a CFIRE-funded project that examined the […]
