Introduction
For almost five decades, Kumares C. Sinha has contributed to transportation engineering over a spectrum of areas from highway engineering, traffic operations, and safety analysis to land use–transportation system modeling, transportation financing, and civil infrastructure management. He pioneered integrated highway-asset-management techniques with innovative research on facility condition modeling, treatment effectiveness, life-cycle costing, and multiobjective optimization of system performance to determine the best times and the optimal levels of effort for renewing and repairing pavement, bridges, and other facilities. KCS is a member of the National Academy of Engineering, and a national associate of the National Academies.

Article
The results of experiments testing the public use of automobiles in the United States are presented. The Purdue Mobility Enterprise system was a work-based shared-vehicle concept, where households used mini/micro-class automobiles for normal daily travel, and full-sized shared vehicles for less frequent but more demanding trips. Comparisons between...

A distance-based highway pricing scheme has been considered a means to tackle highway revenue shortfalls as an alternative to the current taxation on motor fuels. To establish fee rates for a distance-based pricing scheme, this study argues that maintenance and management of the highway system be self-financed by its users, who are responsible for...
Article
Full-text available
The effect of trucks on the level of service is determined by considering passenger car equivalents (PCE) of trucks. The Highway Capacity Manual (HCM) uses a single PCE value for all tucks combined. However, the composition of truck traffic varies from location to location; therefore a single PCE-value for all trucks may not correctly represent the...
