1. INTRODUCTION Growing population, funding realities/opportunities, and rapidly changing technologies continuously affect transportation in Arapahoe County. The County is geographically and demographically diverse. The western portion of the County is where congestion, delay, and bottlenecks have the most impact on vehicular travel, and multimodal infrastructure and programs present opportunities for travel mode choice. The central portion of the County is where new development is occurring and the transportation network is transitioning from rural to suburban/urban, so planning and integrating transportation and land use needs are essential. Further east, the rural area of the County will require new transportation facilities and connections for pockets of growth and development, additional mobility options, and design focused on increased safety.

This existing conditions report provides an overview of current travel patterns and trends within Arapahoe County, the condition of transportation infrastructure, current safety conditions, transportation services, and projects in the current County Capital Improvement Program.

. Collectors – The collector system connects local streets to arterial roadways. These streets serve short to medium distance trips at moderate to low speeds. Typically, the characteristics of collector streets discourage longer distance travel more suitable for arterials. . Locals – The local roadway network provides direct access to local land uses at low speeds. This is the lowest classification of roadway and includes local streets in urban areas and rural secondary roads. These streets serve short length trips at low speeds, with the exception of rural secondary roadways that may have high travel speeds, but still carry relatively low traffic volumes.

Figure 3-1 and Figure 3-2 show the existing roadway functional classification system across the entire county and the west urban area, respectively. The maps include freeways, expressways, and major arterials throughout the entire county. Minor arterials and collectors are also shown in the unincorporated County, but many of the roads classified by municipalities as minor arterials or collectors are not shown.

The County currently classifies all arterials, including expressways, major arterials, and minor arterials, in the broad category of “arterials” within their GIS data system. The TMP team is currently in the process of developing a refined categorization of arterials into subcategories.

APPENDIX A. ARAPAHOE COUNTY LOCAL ROAD SAFETY PLAN EXECUTIVE SUMMARY

Existing Conditions Assessment A

Arapahoe County Local Road Safety Plan

February 2020

Prepared by DiExSys, LLC

EXECUTIVE SUMMARY

A countywide Local Road Safety Plan for Arapahoe County has been prepared. Its focus is to assist the County with data driven decision support analysis for planning and prioritization of safety needs on Arapahoe County Roadways. It accomplishes this by identifying opportunities for cost-effective road safety improvements. Its emphasis was on congested roads in Arapahoe County with some consideration of rural county roads with lower traffic volumes. (As specified in the scope of work, locations entirely within the City of Aurora have been excluded).

The guiding principal behind an effective road safety program is that the resources should go to where they achieve the greatest safety effect. The cost-effectiveness is measured by the Benefit-Cost (B/C) ratio which represents the ratio of the benefits derived from crash reduction expressed in dollars to the cost of construction and maintenance over the life cycle of the project. The primary goal for the program/project selection criteria is to select projects in such a way that, following implementation, they will maximize crash reduction in Arapahoe County within constraints of the available budgets.

The study used the Countermeasure with Promise (CWIP) approach to identify locations with potential for crash reduction. CWIP approach begins by choosing an effective countermeasure first and then looks for sites where it can be applied cost-effectively. The study focused on the following problems susceptible to correction: • Roadway departure crashes on rural segments (overturning, fixed object crashes, head-on and sideswipe opposite crashes) • Approach turn (left turn opposite) crashes at intersections • Broadside crashes at intersections • Rear end collisions at and near intersections • Pedestrian and bicycle crashes at intersections Additionally, the study analyzed safety performance at intersections with signals operated by Arapahoe County.

Following network screening analysis and diagnostic examination the study identified 77 potential safety projects. Each location was analyzed to assess the nature and magnitude of the safety problem using Colorado-specific predictive and diagnostic tools, followed by the development of countermeasures and benefit/cost analysis of proposed improvements. These projects were then ranked ordered by their benefit/cost (B/C). The ranked list of proposed projects is summarized, including B/C, at the end of the report beginning on Page 400. They are also listed in descending order by B/C, below.

Opportunities to reduce impaired driving and to improve EMS response were also reviewed.

Following completion of a draft report, a meeting with stakeholders was held at which all recommendations were presented and reviewed. Interactive GIS map with locations and proposed scope of all projects has also been published and made available to stakeholders to solicit further input. Comments received as a result of the meeting and from the GIS map have been reviewed and this report has been revised to reflect them.
