Public transit is an integral part of Colorado's multimodal transportation system providing mobility to thousands of residents and visitors throughout the state. Not only does transit connect residents, employees, and visitors to major activity centers for jobs, schools, shopping, medical care, and recreation, but it also promotes greater personal independence. Provision of transit services contribute greatly to the economic, social, and environmental health of the state and provide many benefits to individuals and communities in both rural and urban areas from fostering economic development along routes and at station locations to creating mobility options for all., prepared for Colorado Department of Transportation, Division of Transit and Rail ; prepared by Felsburg Holt & Ullevig ; in association with: Cambridge Systematics, Nelson/Nyugaard Consulting Associates, OV Consulting, TransitPlus., Executive summary in English and Spanish., Description based on online resource; title from PDF cover; (viewed July 2015)

Strategic Transportation, Environmental and Planning Process for Urbanizing Places, or STEP UP, is an environmental streamlining pilot project. This report discusses the recommended steps and costs implementing STEP UP across Colorado., "September 2007.", "Report No. CDOT-2007-13.", Mode of access: World Wide Web.
Bridge decks deteriorate faster and require more maintenance and repair than any other structural components on highway bridges. Topical protection systems act as barriers to protect bridge decks from corrosion damage by preventing water, oxygen, and chloride ions from reaching the reinforcement. This study evaluated topical protection systems commonly used on highway bridge decks in Colorado, including low-permeability concrete overlays and waterproof membranes with asphalt overlays., Cover title., "August 2010.", "Report No. CDOT-2010-6, final report.", Includes bibliographical references (p. 58-60), Mode of access: World Wide Web.
While much has been achieved in upgrading and improving the Traffic Records System in Colorado, significant problems remain. Most databases still function as islands of information with limited data sharing and integration. Data remains inconsistent from one dataset to another. The quality of some data is questionable and accessibility is limited. While an initial plan was to develop a Traffic Records Virtual Data Warehouse (TRVDW) to provide a comprehensive, complete, accurate, data resource, the TRVDW feasibility study revealed the concept to be too costly for implementation. This Strategic Plan provides a number of goals and objectives for improvements to the Traffic Records System. All of them serve the ultimate goal of a well integrated Traffic Records System delivering timely, high-quality data for appropriate traffic safety decisions at all levels., "May 2012.", Online resource; title from PDF cover (viewed December 2015)
The overall conclusion of the study is that application of magnesium chloride deicer having a chemical composition and application rate similar to those of 1997-98 is highly unlikely to cause or contribute to environmental damage at distances greater than 20 yards from the roadway. Even very close to the roadway, the potential of magnesium chloride deicer to cause environmental damage is probably much smaller than that of other factors related to road use and maintenance, including pollution of highway surfaces by vehicles and use of salt and sand mixtures to promote traction in winter. Magnesium chloride deicer may offer net environmental benefits if its use leads to a reduction in the quantity of salt and sand applied to roadways. The environmental safety of magnesium chloride deicer depends, however, on low concentrations of contaminants and avoidance of rust inhibitors containing phosphorus. Appropriate specifications for vendors and routine testing can insure the continued environmental acceptability of magnesium chloride deicers. Deicers provided by vendors should be monitored independently by CDOT for chemical characteristics. Any significant changes in processing or source material should be disclosed by the vendor. Colorado-based specifications should be developed for vendors. Independent specifications for low elevation could be developed, or the more stringent high elevation specifications can be applied to all purchases., Final report., "Performed by, Western Environmental Analysts"--Technical report documentation p., "Prepared in cooperation with the U.S. Dept. of Transportation, Federal Highway Administration"--Technical report documentation page., Sponsored by Colorado Dept. of Transportation., "November 1999.", Includes bibliographical references (leaf 34)., Mode of access: World Wide Web.

Self-consolidating concrete (SCC) is a stable and highly flowable concrete that consolidates without the help of external vibration and can flow through heavy reinforcement and around corners in complex formwork under its own weight. The exceptional performance of this remarkable material has attracted the attention of construction firms and DOTs in the United States interested in using SCC on new bridge construction and bridge repair projects., Cover title., Report No. CDOT-2007-1, Interim Report.", "April 2007.", Includes bibliographical references., Mode of access: World Wide Web.
The purpose of this study was to determine the procedures and possible benefits associated with flowing concrete. Based on the study presented in this report, it was determined that SCC was used successfully in the I-25 bridge replacement project in Trinidad. Unfortunately, the all-around lack of construction experience with SCC resulted in numerous aesthetic problems that are atypical of the material., "Report No. CDOT-2010-9, Final Report.", "Sponsored by the Colorado Department of Transportation in cooperation with the U.S. Department of Transportation Federal Highway Administration.", "December 2010.", Includes bibliographical references (p. 25).
States' Departments of Transportation (DOT) are trying to utilize the best practices of managing low-volume roads (LVRs) due to limited resources and declined transportation funding. Diverse maintenance practices and fluctuating budget allocations are noticed on LVRs which significantly impact the overall pavement performance. In this study, the optimal scheduling of maintenance strategies and effectiveness of different maintenance policies are investigated., Marwan Hafez, Khaled Ksaibati, Rebecca Atadero., "February 2020.", Report No. CDOT-2020-03, Online resource; title from PDF cover (viewed March 2020)
