We examine the impact of relationships between contractors and subcontractors on firm pricing and entry decisions in the California highway procurement market using data from auctions conducted by the California Department of Transportation. Relationships in this market are valuable if they...

During the past decade, new sensing technologies, such as inductive loops, laser range scanners, radar detectors and computer vision sensors have been greatly enhanced and applied to the Intelligent Transportation System (ITS) area. Among all these sensor systems, computer vision-based...

Many metropolitan areas are struggling with how to accommodate future population growth—and are looking to transit-oriented development (TOD) as a potential solution. TODs, in which densely-built, mixedincome housing is placed near transit to create walkable neighborhoods complete with...

Transportation investments have in the past among society’s most important contributors to environmental improvement, but today transportation programs and projects are more often of concern as sources of major environmental problems. Over the past 30 years, since the enactment of the...

The major purpose of this research is to test the effects of street-level urban design attributes on travel behavior. There are two goals: (1) operationalizing path walkability, which includes developing a walkability measurement instrument and quantifying path walkability, and (2) testing the...
