Peer grouping and performance measurement to improve rural and urban transit in Texas (open access)

Peer grouping and performance measurement to improve rural and urban transit in Texas

"Rural and small urban transit systems in Texas will become even more important with predicted changes in population trends. Rural demographic trends indicate growth in the number of persons age 65 and over coupled with a decrease in population density. Small urban area trends indicate substantial population growth and broadened geographic boundaries, yet resources to provide rural and small urban transit are limited. Therefore, transit managers find it is increasingly important to maximize service efficiency and effectiveness. The purpose of this research was to identify peer groups, performance benchmarks, and strategies used by successful transit providers to achieve high performance. The research project identifies peer groups based on the transit environment within which each agency operates, so that agencies can be compared to other operators who face similar environments. Peer group effectiveness and efficiency performance are examined within and between rural and urban peer groups, and high performers are identified for case studies. Through the case studies, key attributes are identified for achieving high operating efficiency and/or effectiveness. Performance strategies are categorized to provide transit providers with transferrable information to improve performance and increase the return on transit investment."

"The report examines sustainable supply chains in North America and the role played by rail inter-modal operations in lowering ten-mile fuel and emission costs. It examines whether current systems favor imports over exports - a current complaint from some shippers - and whether the development of inland inter-modal ports offers a solution to moving future freight into and out of large metropolitan areas."
