Assessment Of The 1997 Commodity Flow Survey For State-Level Freight Transportation Planning, Darren M. Scott
Assessment Of The 1997 Commodity Flow Survey For State-Level Freight Transportation Planning, Darren M. Scott
Kentucky Transportation Center Research Report
Urban travel demand modeling in the United States has a rich history in both practice and academic research. The same cannot be said, however, of freight demand modeling despite the intermodel planning requirements of IS TEA and TEA21. In most instances, agencies responsible for state transportation planning (e.g. Kentucky Transportation Cabinet) have applied, in a limited way, the methodology developed for urban travel demand modeling (i.e., Urban Transportation Modeling System or UTMS 1) to the freight arena (see, for example, Black 1997). Obviously, this methodological similarity implies that the fundamental data requirements for both types of demand modeling are also …
Probability Of A Hazardous Material Truck Accident In New Jersey, Mahesh Damodaran
Probability Of A Hazardous Material Truck Accident In New Jersey, Mahesh Damodaran
Theses
Accident prediction modeling is a powerful tool for determining the frequency of accidents under certain circumstances. Nationwide, direct damages from highway hazardous material spills for the year 2000 were tallied at over $31billion. This thesis determines the probability of an accident involving hazardous materials on the roads of New Jersey. The methodology is based on a British predictive equation used by their Highways Agency to determine the probability of a hazardous spill over a section of a roadway. The parameters used by the British's Highways Agency, which is obtained from their accident data, were modified to reflect conditions that best …

Kentucky Highway User Survey 2001, Ronald E. Langley, Ted Grossardt
Kentucky Transportation Center Research Report
The purpose of this study was to continue the efforts begun in 1997 to monitor Kentucky public opinion regarding the quality of the highway system and also includes a portion to measure satisfaction with the current drivers’ license and registration renewal processes. Kentucky’s 2001 public opinion is compared to data collected since 1997 to gauge Kentucky’s progress over the past years.

Effectiveness Of The Borman Expressway Its Program On Local Air Quality, Timothy M. Labreche, Robert Bertram Jacko, Barry K. Partridge, William H. Schneider, Ahmed S. Soliman
JTRP Technical Reports
Particulate Matter less than 2.5 μm in diameter (PM2.5), carbon monoxide (CO), and meteorological parameters were monitored at 10 second averaging intervals adjacent the Borman Expressway in Northwestern Indiana before and during the implementation of an Intelligent Transportation System. Traffic data was collected from sensors on the expressway. The high-resolution data permitted the expressway contribution to local air quality to be separated from background components of local air quality and significant correlations were made between pollutant flux and traffic flow and pollutant flux and highway occupancy. Traffic incidents (accidents / congestion) were shown to have a rapid impact on local …
