Review on Roadway Maintenance and Transportation

The Relationship between Urban Density and Roadway Maintenance Costs

Urban land-use planning in the U.S. has traditionally been bas ed on the Euclidean zoning model, the separation of land uses. The long-term impacts of this development pattern, often termed “urban sprawl”, have been a continued source of controversy (1). This research determines if expert opinion regarding sprawl’s negative effects, specifically, that regarding the public/ private capital and o...

Estimation of Reconstruction Cost and Traffic Functionality Relating to Roadway Transportation Lifelines after Natural Disasters

Earthquakes are among those natural hazards which may lead to disruption in the function of arterial traffic routes. Road networks are particularly vulnerable, due to their geographical dispersion, extensive functions and structural reliance on favourable geophysical conditions. Traffic functionality after a natural disaster and the repair/rehabilitation cost of roads are crucial considerations...

Improve the safety and efficiency of roadway maintenance phase I: Developing a robotic roadway message painter prototype

Integrating fixed and mobile arterial roadway data sources for transportation analysis

Integrating fixed and mobile roadway data 2 ABSTRACT Fixed-site and mobile data sources have distinct strengths for representing roadway conditions, and unique insights can be generated by combining the two. Ongoing research on an urban arterial roadway corridor combines distinct data sources for multi-criteria transportation facility performance assessment. The roadway is instrumented with an ...

Development of an Online Roadway Geometry Design Software for Transportation Education and Training

Traditionally, students use pencil and ruler to lay out lines and curves over contour maps for roadway geometry design. Numerous calculations of stopping sight distance, minimum turning radius, and curve alignments are required during the roadway design process in order to ensure safety, to minimize economic and environmental impacts, as well as to reduce construction costs. Students usually pe...
