Project Overview

Through the American Planning Association’s Plan4Health program, Trailnet is thrilled to announce the Misssouri Chapter of the American Planning Association–working with the Healthy Eating Active Living (HEAL) Partnership–has received a $120,000 grant for community engagement activities. This will present a vision for safe access to physical activity for pedestrians throughout the City of St. Louis. Engaging the community through pop-up demonstrations, the partnership is addressing walkability and highlighting ways to build better streets with traffic calming solutions.

As part of the Plan4Health St. Louis project, the HEAL Partnership is working with local experts to create a variety of tools that can be used in temporary demonstrations for traffic calming. These tools will be used for pop-up demonstrations in the following focus areas: the Ville and Greater Ville, JeffVanderLou, Dutchtown, and Carondelet. The pop-up demonstrations offer possible solutions and provide fun and safe social spaces to St. Louis residents while also encouraging healthy, active living.

The Healthy Eating Active Living (HEAL) partnership members include: Trailnet, City of St. Louis Department for Health, City of St. Louis Streets Department, Missouri Chapter of the American Planning Association, Missouri Public Health Association, Missouri Foundation for Health, Great Rivers Greenway, Gateway Greening, GirlTrek, The YMCA of Greater St. Louis, Washington University, Saint Louis University,Paraquad, and American Heart Association.

We built a toolkit to make it easy for everyone to create their own pop-up traffic calming demonstrations and show how streets can be designed for those who walk and bike. Take a look at Slow Your Street: A How-To Guide For Pop-up Traffic Calming.

This project was inspired by Kirkwood’s successful pop up plaza as a way to reimagine space for its resident. For a recap of the event please go to our blog post – Kirkwood Plan Review and Pop-up Plaza – October 25, 2014.

Traffic Calming

Traffic calming makes streets safer for people who walk and bike by reducing the speed at which cars travel. Slowing car traffic and reducing cut-through traffic helps make streets feel more friendly, livable, and welcoming to residents of all ages. As defined by the Institute of Transportation Engineers, “Traffic calming involves changes in street alignment, installation of barriers, and other physical measures to reduce traffic speeds and/or cut-through volumes, in the interest of street safety, livability, and other public purposes.”

Project for Public Spaces created helpful tips and information to know, such as a traffic calming toolbox. Check out their Traffic Calming 101 toolbox for more information.
