This research project observes and analyzes traffic and accident history on Colorado State Highways and parallel arterial roads within a major southeast section of the Denver Metropolitan Area. The project focuses on the freeway section of C-470 between S. Santa Fe Drive and I-25 and comparisons with I-25 and the corresponding parallel east-west regional arterial corridors., Ron Hensen, Joe Miyaki., "Prepared in cooperation with the U.S. Department of Transportation, Federal Highway Administration."--Technical report documentation page., "November 2015.", Research performed by Short, Elliott, Hendrickson, Inc.

Wildlife crossing structures (WCSs), underpasses, and overpasses are widely used for the safe travel of larger wildlife species across roads and highways, reducing wildlife-related vehicle collisions to drivers. WCSs are often expensive to build and maintain, and therefore determining a cost-effective, optimal design is a challenge faced by departments of transportation across the United States and elsewhere. Although much research has been conducted on the variables affecting the usage of WCSs by wildlife, few attempts have been made to correlate cost-diminishing returns in relation to the success rates and optimal sizing of WCS., Pat Basting and [4 others], "March 2022.", Online resource; title from PDF cover (viewed April 2022), Report No. CDOT-2022-01
This is the second of a two-part research effort to determine how to improve the effectiveness of CDOT safety efforts. This effort focuses on the safety culture within CDOT and the effectiveness of the CDOT safety programs on improving safety culture. The study used a survey approach based on interviews with senior safety officials to determine the scope of the survey questions. Based on the survey results, it is recommended that CDOT continue to engage in culture enhancement activities. Of particular importance is the continued discussion of the Excellence in Safety program and the undertaking of a follow-up effort to understand why specific regions have a higher level of implementation and change than others. Additionally, the effort needs to focus on understanding the differences in perception between supervisory and field crew personnel., Paul S.
