Neighborhood Bikeway Traffic Management Study

W 35th Avenue and Garfield Street

In 2015, feasibility studies of W 35th Avenue and Garfield Street identified each corridor as ideal candidates for becoming Neighborhood Bikeways (NBWs). Neighborhood Bikeways are roadways that are designed to provide a comfortable and attractive bicycling environment in shared street conditions. The results of these studies recommended techniques to prioritize comfort and safety for people bicycling along each corridor.

While the bicycle and pedestrian improvements recommended in these studies have entered the design process, comments received during the public comment process yielded concerns about vehicle speeds and a lack of stop sign compliance from both motorists and bicyclists. To address these concerns, Denver Public Works is updating policies and procedures for Neighborhood Traffic Management Strategies and is introducing new traffic calming strategies, including traffic circles, chokers, and chicanes. As part of the process for developing NBWs, this study will identify how these new strategies might be used along each corridor and develop criteria to determine which treatments are most effective for specific locations.

Demonstration Projects

Based on the previously completed neighborhood bikeway feasibility studies, this study will identify segments of the W 35th Avenue and Garfield Street corridors for demonstration projects testing these traffic calming concepts.

The temporary installations will involve low cost designs that will allow the city to monitor and evaluate how the treatments affect traffic. Denver Public Works will use findings from these two cases studies to recommend the city’s policies for neighborhood traffic management strategies.

Schedule

This project has an anticipated 12 month schedule, with a series of public meetings to inform residents and stakeholders about the project and provide an opportunity for questions. We also anticipate attending several RNO meetings in each project and demonstration area.

Demonstrations will last from four to eight weeks and will be implemented using temporary pavement markings and traffic devices, such as barrels or flexible posts, along with project information signs to alert street users and residents of the demonstration projects along W 35th Avenue and Garfield Street.

Proposed demonstration segments

  • Between three and five blocks in length
  • Will not include traffic signal additions or modifications
  • Will not include traffic diversion treatments; they will focus on speed control treatments

In addition, the city will define performance measures and collect traffic data, field observations and information to evaluate performance of the demonstration projects. Based on the outcomes of the demonstrations, we will provide recommendations including criteria for selecting the appropriate type of treatments for use on future neighborhood bikeway projects.

 

Examples of traffic calming in other cities

Traffic circles slow vehicles at intersections

Curb extension acts as a choker to narrow travel lanes

Chicanes alternating along roadway lower traffic speeds

 
 
Project Status: Study

This study will develop demonstration projects to evaluate traffic management strategies along two prospective Neighborhood Bikeways in Denver.
