Transportation systems generate certain health-promoting benefits such as access to social, economic, and cultural resources, but they also are a source of air pollution, noise, safety hazards, and barriers that diminish social cohesion in neighborhoods. Streets, in particular, are among the most important...
With over 90,000 miles of roadway classified as local roadways (county and township) in the state of North Dakota, local road quality has a large impact on commodity movement, safety, and the quality of life for its residents and visitors. Local road managers have long faced the difficulties of properly...
The built environment consists of everything humanly made, arranged, or maintained (Bartuska and Young 1994).

While aggregate data is helpful, segmenting a market into smaller groups allows for more targeted planning, promotion, operation, and evaluation. In this study, intercity market segments based on...
ATAC worked with the Bismarck-Mandan Metropolitan Planning Organization on updating the regional travel demand model. The work included updating the transportation network; updating the socio-economic data for the traffic analysis zones (TAZ); and calibrating the model to the 2007 traffic data. Once...
ATAC worked with the Fargo-Moorhead Metropolitan Council of Governments on updating the regional travel demand model. The work included updating the transportation network; updating the socio-economic data for the traffic analysis zones (TAZ); and calibrating the model to the 2005 traffic data. Once...
Previous studies on daily time allocation have shed light on individuals' trade-offs regarding time allocation within a fixed time budget. However, interpersonal interactions of time allocation with a social network are far from being understood, largely due to limited research in this area. Further...
ATAC completed a major update of GF-EGF MPO's Regional Travel Model to account for transportation and socio-economic changes since the previous model update. The update also included an upgrade of the model software from Citilab's Tranplan to TP+, a more powerful modeling software. ATAC also converted...
This paper presents a prototype safety improvement program (SIP), which was developed specifically for unpaved roads. The combination of high mileage, low traffic volume, and limited budgets make it difficult for local agencies to adopt traditional safety improvement programs. The SIP for unpaved roads...
