<title>A<sc>bstract</sc> </title> In this article, we estimate a Tobit model of property damage costs of crashes that occur at signalized intersections with data from one US city -- Greensboro, North Carolina. The model includes data on technological variables, types of crash, types of vehicle, traffic and intersection...

This note examines if offsetting driver behavior affects rear end crashes at intersections with red light cameras. It models offsetting driver behavior and estimates simultaneous probit equations to analyze this behavior. It finds that in the city considered the effect of red light cameras on...

This is an update to the October, 2003 version of this report. Using the latest available data, we include an additional 12 months of accident data. Additionally, several data coding errors were discovered in the original data set, and corrected for this report. Therefore, results from the...

This study extends the previous work of Burkey and Obeng (2004) that examined the impact of red light cameras on the type and severity of crashes at signalized intersections in Greensboro, NC. The extension takes the following form. First, we extend the data to cover 57 months, and to include...

This paper identifies the characteristics of strategic planning systems of transit agencies that enhance these agencies' abilities to respond effectively to federal legislative requirements and mandates, and have positive community impacts. These characteristics are, each unit or division must...

U.S. urban transit systems receive operating and capital subsidies from various levels of government. Each firm minimizes its cost net of subsidies subject to its production function. The first order conditions from this minimization give a set of equations that are estimated using a stochastic...

There are many studies, including those of J. Pucher et al. and S. C. Anderson, that found higher costs to be associated with transit operating subsidies. However, none of them investigated the effect of state and local federal subsidy formulas on cost efficiency of transit operations. In this...

Performance in single mode bus transit systems is analyzed in this paper. The paper points to two potential problems in using partial productivity and other measures in assessing the performance levels of transit systems. One solution suggested is total factor productivity which is shown to be...

This paper investigates total factor productivity as a unified measure of transit performance. The approach uses the shift in the cost function of inputs and outputs as the measure of change in productivity. A three step regression procedure was used to estimate model parameters. The approach...
