Highway assets, including traffic signs, traffic signals, light poles, and guardrails, are important components of transportation networks. They guide, warn, and protect drivers and regulate traffic. To manage and maintain the regular operation of the highway system, state departments of transportation...

 

Maintenance management has relied heavily on collecting asset condition information to plan maintenance activities and budget allocation. Data collection is often conducted on a sampling basis because of resource constraints. There is thus a perceived need for the development of an effective sampling...

 

Over the last two decades, the use of advanced scientific and data-driven statistical methods has been continuously evolving to reduce the frequency and severity of crashes on our roadways. The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) was...

 

Perception-reaction times (PRT) and deceleration rates are critical components in the design of highways and streets. This research has several objectives, including 1) evaluate differences in PRT and deceleration rates between crash and near-crash events, 2) assess the correlation between PRT and deceleration...

 

The South Dakota Department of Transportation (SDDOT) currently has a Finite-Element Surface-Water Modeling System for Two-Dimensional Flow (FESWMS-2DH) and Research Management Associates 2 (RMA2) Both programs have the capability to model two-dimensional (2D) flow around structures. The department must...

 

Redundancy is vital for transportation networks to provide utility to users during disastrous events. In this project, we develop two network-based measures for systematically characterizing the redundancy of transportation networks: travel alternative diversity and network spare capacity. The travel...

 

Strategies often proposed to combat the growing traffic congestion problems of urban environments target enhancements to increase the use of bus transit. Therefore, service providers are keen to identify and understand factors that could attract more transit riders. Other than affordability, most researchers...

 

Livability is a fairly new concept well understood in urban areas, but less so in rural areas and Indian reservations. A methodology was developed to identify the important livability issues for Tribal communities and consists of data collection, analysis, and development of the program. The methodology...

 

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 was initiated to provide assistance to counties that were experiencing considerable impacts to their road systems from oil and gas drilling but were not receiving sufficient revenue to keep up with these impacts. As drilling expanded from Campbell County into Sheridan and Johnson counties...
