In 2002, CDOT undertook this study in an effort to better understand the complexities of the Federal Highway Administration's new Traffic Noise Model (TNM). The research involved three analysis.
In this study, the Regional Transportation District's (RTD's) light rail operations were examined for pollutant production and runoff. Conclusions from the study: Water leaving ballasted tracks carries only a small fraction of the heavy metals that are introduced into tracks from the light rail operations. Heavy metal concentrations at the most heavily traveled light rail station showed that pollutant concentrations were far below the regulatory limits.
The Colorado Department of Transportation (CDOT) is currently investigating approaches to reduce the frequency and severity of work-related injuries. The incident rates for CDOT are significantly higher than those achieved by some private organizations and comparable DOTs.
The Colorado Department of Transportation (CDOT), Department of Transportation Development (DTD) conducted a study to evaluate the usefulness of the Quantm system for planning transportation improvements in Colorado.
STEP UP, the Strategic Transportation, Environmental and Planning Process for Urbanizing Places, is an environmental streamlining project for Colorado to develop an improved process for addressing environmental impacts related to transportation projects at the earliest stage and the tools to implement the process.
