Automated placement and retrieval of traffic cones
Automated placement and retrieval of traffic cones
This research report documents the findings of an investigation into automated temporary traffic control device (TTCD) deployment and retrieval technologies. The researchers found that some automated TTCD deployment and retrieval products may reduce one or more types of worker risk while increasing other types of risk. A fully automated product has the potential for the greatest risk reduction overall, but also has a much higher cost than less complex systems., LuAnn Theiss and Gerald L.

Benefit-cost analysis of CDOT fixed automated spray technology (FAST) systems
Benefit-cost analysis of CDOT fixed automated spray technology (FAST) systems
The study found that FAST systems have demonstrated the potential to reduce the number of crashes and reduce the cost of winter maintenance activities, if sited at appropriate locations (e.g., high-traffic-volume ice-prone ramps). However, improved installation techniques and involvement of maintenance crews during FAST installation are necessary to further increase the cost-effectiveness of a FAST system deployment. Extra effort will be made in sharing the information gained from this research study by focusing on CDOT personnel involved in planning, design, construction, operation and maintenance of FAST systems., Anburaj Muthumani, David Veneziano, Jiang Huang and Xianming Shi., "October 2014.", Prepared in cooperation with the US Department of Transportation, Federal Highway Administration., Bibliography: page 71-75., Report No. CDOT-2014-11., Online resource; title from PDF cover (viewed April 2016)
Best practices for full-depth reclamation using asphalt emulsions
Best practices for full-depth reclamation using asphalt emulsions
Full depth reclamation of asphalt pavements using asphalt emulsions is a process that recycles and rejuvenates the existing asphalt pavement surface, base, and sometimes, the subgrade, providing an improved underlying structure for the new asphalt pavement. This report provides guidance, standardized plans and specifications, construction inspection best practices materials testing procedures and frequencies, a performance evaluation process, and quality assurance and quality control protocols when constructing FDR projects., Scott Shuler., "July 2015.", Prepared in cooperation with the US Department of Transportation, Federal Highway Administration., Bibliography: pages 33-35., Report No. CDOT-2015-04., Online resource; title from PDF cover (viewed April 2016)

Best practices to support and improve pavement management systems for low-volume paved roads. Phase I
Best practices to support and improve pavement management systems for low-volume paved roads. Phase I
The Colorado Department of Transportation (CDOT) has been trying to identify the most effective methods for managing low-volume roads (LVRs). These roads are facing multiple challenges including: reductions in maintenance budgets, impact of industrial activities, and potentially not receiving the most cost effective treatments. Considerable savings can be secured by implementing an effective and informed management system for all LVRs engineering issues, including: planning, design, and maintenance., Marwan Hafez, Khaled Ksaibati, Rebecca Atadero., "February 2018.", Report No. CDOT-2018-03, Online resource; title from PDF cover (viewed August 2019)
Bicycle safety lesson plans: 3rd through 6th grade
Bicycle safety lesson plans: 3rd through 6th grade
As recently as 1969 about half the school aged children in the United States walked or bicycled to school. Today fewer than 15% of school children walk or bike to school and as much as 20-30% of morning traffic is generated by parents driving their children to school. Children are less active today and the majority of children living within a 1/2 mile of schools are driven in private vehicles. Obesity rates are on the rise and the cost of obesity and other health related challenges have significant impacts on the rising cost of health care in the Unites States, not to mention the lifestyles of our children. In response to these challenges, in an effort to encourage healthy living, the Colorado Department of Transportation has developed a series of pedestrian and bicycle safety lesson plans in support of the Colorado Safe Routes to School program. These lesson plans, which help educators teach children about safe walking and bicycling, introduce a variety of skills that can help children stay safe while they walk by teaching them skills that will help them safely cross the street. Statistics show that child pedestrians are disproportionately represented in injury crashes and that the typical factors in those crashes that can be mitigated by education and practice., Online resource; title from PDF cover (viewed November 2016)

Bridge deck repair investigation and quantity estimation
Bridge deck repair investigation and quantity estimation
This report presents a case study on the evaluation of bridge decks using various non-destructive test methods. The primary interest lies in quantifying delaminated areas in deck concrete covered with asphalt overlays. Analytical and computational models are formulated to decompose the intensity of GPR scales into two categories: i) initiation and progression of corrosion and ii) delamination of deck concrete, which show good agreement with repaired areas. Parametric investigations emphasize the significance of rebar spacing and concrete cover in determining the extent of deck delamination., Yail Jimmy Kim., "December 2020.", Performing organization: University of Colorado Denver., Includes: University of Colorado Denver inspection of bridge decks with ground penetrating radar., Includes bibliographical references (pages 28-33 ), Report CDOT-2020-19, Online resource; title from PDF cover (viewed May 2021)
