Project Overview

Notice of Upcoming Work: 17th & Grove Art Installation on 10/24 (Sunday). Photos coming soon!

The Vision Zero Innovation Program (VZIP) is dedicated to installing innovative, quick-build improvements on city streets in 2020-2021.

VZIP projects are intended to accelerate progress toward creating safer streets to help our community achieve our Vision Zero goal of eliminating fatalities and serious injuries caused by severe traffic crashes. View a map of VZIP projects installed across the city.

2021 Projects

VZIP projects will be installed at the locations below starting in September 2021. View map of installed projects.

Note: Once installed, the spacing and dimensions of elements may vary slightly from the designs shown below, given real-world conditions. Some designs were modified following the July Neighborhood Forums, based on resident input.

Pedestrian crossing treatment with curb extensions. Photos coming soon.

See photos below for visual details. Installed treatments include pinch points (installed near GlenLake Apartments and west of 30th St.) and curb extensions (installed near 29th St). Pinch points help reduce vehicle speeds by created a yield condition between traffic traveling in opposite directions on the street. Curb extensions slow down vehicle turns and increase pedestrian crossing comfort.

Glenwood VZIP 2

See photos below for visual details. Installed treatments include a pinch point (installed south of Aurora), curb extensions (installed at Inca and Talbot north and south), median islands (installed at Inca and Talbot north and south) and a flex post centerline (installed near Aurora and at Inca). Pinch points help reduce vehicle speeds by created a yield condition between traffic traveling in opposite directions on the street. Curb extensions slow down vehicle turns and increase pedestrian crossing comfort. Median islands provide refuge space and increase pedestrian crossing comfort. Flex post centerlines provide further visual emphasis to encourage vehicle travel within designated travel lanes.

Palo Pkwy VZIP

See photos below for visual details. Installed treatments include a pinch point (installed east of 15th), curb extensions (installed near 17th and 19th) and a chicane (installed in the 1700 block of Quince). Pinch points help reduce vehicle speeds by created a yield condition between traffic traveling in opposite directions on the street. Curb extensions slow down vehicle turns and increase pedestrian crossing comfort. Chicanes create visual "friction" in the road, encouraging slower speeds and greater awareness of other roadway users.

Quince Ave_Sept 2021

See photos below for visual details. Installed treatments are located at two existing pedestrian crossings (one west and one east of Chaparral) and include both curb extensions and a median island. Curb extensions slow down vehicle turns and increase pedestrian crossing comfort. Median islands provide refuge space and increase pedestrian crossing comfort.

Frequently Asked Questions

The posts were installed through the city’s Vision Zero Innovation Program to help reduce vehicle speeds. These types of installations have been used effectively in cities around the world and are new to Boulder.

Their purpose is to encourage slower vehicle speeds by physically narrowing the street. By design, the installations are intended to cause drivers and other road users to slow down and pay attention to their surroundings, which creates safer street environments for people walking and bicycling. On some streets, the posts also extend the curb and/or create a median island, which provides safer crossings for pedestrians and bicyclists.

The installations have been designed according to National Association of City Transportation Officials (NACTO) standards and follow industry best practices for speed mitigation.

The posts have been installed because they change the street design in ways that can help reduce speeding. Speeding is one of the top causes of severe traffic crashes in Boulder, and reducing speeding requires two approaches: lowering the residential speed limit to 20 mph, which the city did last year, and changing the street design itself.

Both of these approaches are standard practice for Vision Zero cities. Vision Zero is a commitment adopted by Boulder and cities worldwide to eliminate fatalities and serious injuries caused by traffic crashes – zero serious injuries, zero deaths on our streets.

Since the City of Boulder committed to our Vision Zero goal in 2014, we’ve adopted policies and built projects to make our streets safer. But more progress is needed, and so the Vision Zero Innovation Program was identified as a way to install speed mitigation treatments on city streets at lower cost and on a much faster timeline than typical transportation projects. Finding agile and low-cost ways to create safer streets in Boulder is critical to achieving Vision Zero, especially as the COVID-19 pandemic has reduced the city’s budget for transportation projects.

The posts have been installed in locations where the city and/or nearby residents have identified a need for safer street conditions. Some of the locations are those where the city has observed speeding or dangerous driving. Others are locations where nearby residents submitted a petition to the city to receive speed mitigation measures on their streets, through the city’s Neighborhood Speed Management Program. The designs of the installations built this year also took into account community feedback received during the first year of the Vision Zero Innovation Program (2020), including feedback gathered through virtual neighborhood forums.

Travel slowly around the posts, looking out for all road users. Vehicles always travel around the posts. Bicyclists can travel with traffic or through the posts. Pedestrians can stay on the inside of the installations and travel through them to cross the street.

The designs of the installations were made to allow enough space for snow removal. Staff will be monitoring the installations throughout the snow season for any adjustments to snow plowing.

While we tried to minimize impacts to parking, the removal of some spaces was required to allow room for the installations. In some cases, curbside space near intersections that may have previously been used for parking was reallocated to the speed mitigation installations. These were spaces where it was previously technically illegal to park, due to proximity to the intersection. The posts improve safety in these areas by providing more visibility to people turning, where previously parked vehicles reduced sight distances.

These types of posts were installed because they are noticeable to drivers, low-cost and can be installed quickly. Some installations, such as the new crosswalks and curb extensions at 26th and Spruce streets feature art, and the city will also be adding art to the installations on Grove Street this month. In addition, we installed a crosswalk featuring art at 19th Street and Yarmouth Avenue, with two more planned for some 9th Street crossings. Based on feedback, the city is exploring the possibility of having local artists beautify additional installations.

City staff will be collecting traffic volume and speed data at locations where the posts are installed to evaluate their effectiveness at improving safety and may adjust the installations if deemed necessary.

Community feedback is a key part of the Vision Zero Innovation Program - the city collects feedback on how safe and comfortable people feel when using the new installations and have been collecting this feedback since the program launched in 2020. This feedback helps us make adjustments to the program and the types of speed mitigation installed.

We encourage you to submit your feedback on the installations using this form. Using this form ensures city staff will review your feedback and helps staff evaluate the program.

The purpose of VZIP is to provide transportation improvements that slow vehicle speeds and provide enhanced protection for people walking and biking more quickly and for less money than traditional projects that use concrete and asphalt. For that reason, speed humps/cushions are not an option under the VZIP, which focuses primarily on paint and post installations.

No. Prior to the treatments being installed, these streets already had shared street conditions for motorists and cyclists due to cars parked on the sides of the street. The installations improve visibility for people sharing the street, e.g, pedestrians about to cross the street, because it's easier to see people through the posts than through parked cars.

Program Background

The Transportation and Mobility Department dedicated $250,000 of its Vision Zero funding in 2020 to installing innovative, quick-build improvements on city streets in 2020 and 2021 to enhance pedestrian and bicyclist safety and comfort.

The city's 2019 Low-Stress Walk and Bike Network Plan, which identifies high-risk locations for walking and bicycling in Boulder, is used to help identify locations for VZIP projects. Community feedback, data evaluation and the 2019 Safe Streets Report also inform locations.

Before and after installation, the city collects data and community feedback on the projects to evaluate their effectiveness.

Treatment Types

VZIP uses three main project types, all of which can be made quickly and at lower cost while improving pedestrian and bicyclist safety and comfort:

  • Curb extensions - Shorten the crossing distance for pedestrians/cyclists through the paths of vehicles by physically and/or visually narrowing the roadway (such as with flexible delineators or artistic treatments).
  • Pedestrian and bicyclist crossing treatments - Provide protection for pedestrians/cyclists by ensuring crossing areas are visible to drivers.
  • Traffic calming elements - Reduce vehicle speeds to encourage safer interactions between all road users.

Further Project Details

Staff hosted two virtual neighborhood forums in July to provide information and background on VZIP and the proposed 2021 projects. Thanks to all who attended.

View the Forum #1 (July 21) recording.
View the Forum #2 (July 29) recording.

Darley Avenue was under consideration to receive VZIP treatments.

Based on input from the community as well as additional data and observations staff has decided to not move forward with the proposed project.

The corridor is still eligible for future traffic calming through the Neighborhood Speed Management Program (NSMP) with additional engagement to determine the appropriate project type(s).
