This study was conducted to provide the Oklahoma Transit Association and state policy makers with information that will allow them to plan for mobility challenges and address coming greater mobility needs stemming from population growth and changes in the state’s demographics. In this study, we constructed...

 

A study was conducted to develop recommendations for short span concrete structure type selection based on analyses of existing structure costs and performance data from South Dakota roadway systems. Through a combination of data sources, including the PONTIS database, local owner and inspector surveys...

 

Construction of highways usually requires large areas of land disturbance, which may result in accelerated soil erosion. The stormwater runoff from highway construction sites typically contains a large amount of fine particles that are difficult to remove using conventional best management practices....

 

The Congestion Mitigation and Air Quality Improvement (CMAQ) program was implemented to provide funding to transportation projects that contribute to air quality improvements. Wyoming has used these funds for a number of years to apply dust suppressants to unpaved roads around the state. Many of these...

 

The South Dakota Department of Transportation (SDDOT) allows the use of precast double-tee bridges in counties because they are economical and fast in construction. Alternative durable prefabricated bridge systems are needed to provide more options to local governments. The present study was carried...

 

Building upon the development of a measure of safety culture based on a simplified two-factor model of meaning and behavior, a further validation study of the safety culture instrument was undertaken. The Safety Culture Assessment Survey (SCAS) was administered to a large regional railroad organization...

 

The ultimate objective of this project was to develop widely accepted recommendations on self-consolidating concrete (SCC) mixture design for its use in WisDOT bridge projects. This project investigated the effects of material constituents on the material properties of trial SCC mixtures made from precasters...

 

This report presents a two-phase research program studying i) galvanic current influencing deterioration of carbon fiber reinforced polymer (CFRP) sheets bonded to a steel substrate and ii) electrochemical reaction for steel beams strengthened with CFRP. The first phase of the research presents an experimental...

 

The objectives of this study are to identify data needs for assessing demand-response transit (DRT) level of service, develop a data collection tool for obtaining those data, and develop a method for assessing DRT levels of service and prioritizing needs for service improvements. A survey was developed...

 

This study identifies the needs of transit agencies in North Dakota, gaps in transit service, and additional services and funding needed to meet current demand as well as projected future demand. Objectives are to construct a demographic profile of the state of North Dakota, develop a mobility needs...
