Research Highlights
Real-Time Stochastic Matching Models for Freight Electronic Marketplace
Avinash Unnikrishnan
This grant from the National Science Foundation (NSF) will support research investigating how a real-time marketplace might be constructed to match freight shipments with available carriers. In such a system, freight shippers make a request to the system manager, and an automated service will match shipping jobs to carriers who are likely to accept them. The benefits of such a system include more efficient use of freight capacity (fewer empty miles) and reduced shipping prices, resulting in e...

Understanding Types of Cyclists Nationally

To do so, planners and researchers have developed typologies of cyclists; however, many of these typologies are based upon surveys of current cyclists and, therefore, are of limited use in planning to attract new people to bicycling for transportation. One exception is the “Four Types of Cycl...
