Traffic calming: a lighter, quicker, cheaper way to policy change


Traffic calming: a lighter, quicker, cheaper way to policy change

St. Louis’ most recent effort toward creating safer streets consisted of brightly painted tires, colorful cones, plants, and signs. The Healthy Eating Active Living (HEAL) Partnership in the City of St. Louis is using pop-up traffic-calming demonstrations to raise awareness on how to create safer streets. The materials from the demonstrations will be used to develop a traffic-calming lending library.

Please watch this exciting recap that highlights the positive effect the Plan4Health grant has brought to the community.

This new opportunity for the City comes from a Plan4Health grant from the Centers for Disease Control and Prevention (CDC), in partnership with the American Planning Association (APA) and American Public Health Association (APHA). The objective of the grant is to bring together those who work within planning and public health to improve their communities and make them become more loveable.

The City of St. Louis is like many other cities—built for cars to have the largest advantage in transportation. In the U.S., 12 percent of fatal traffic crashes involve people walking, In St. Louis, however, that figure is 36 percent. In the first six months of 2015, 15 pedestrians were killed in the City of St. Louis, many in hit-and-run incidents. These sobering statistics earned St. Louis a designation as a Focus City by the National Highway Traffic Safety Administration, joining 21 other U.S. cities in which pedestrian deaths are higher than the national average.

Data has shown that wider roads lead to a faster rate of travel for people driving. The graphic below illustrates how higher rates of speed lead to higher rates of traffic fatalities.


Many streets in the City of St. Louis were built to accommodate streetcars and high levels of traffic, so some residential streets are as wide as 65 feet. The traffic calming pop-ups have been a great way for the City and residents to start exploring what to do with the extra space.


Trailnet, a local bicycle and pedestrian advocacy organization and partner within the HEAL Partnership, has been working to address this problem by implementing several pop-up traffic-calming demonstrations throughout the City of St. Louis. The purpose of the events has been to educate community members, elected officials, and city staff on how we can work together to create safer streets. The pop-up traffic-calming demonstrations are less-than-ten-hour events meant to measure the impact street designs have on people driving as well as listen to the community’s suggestions for safer streets.


The Plan4Health grant also offers a unique opportunity for the HEAL Partnership to develop a traffic-calming lending library so community members who are interested in demonstrating their own pop-up traffic-calming events have the resources and tools to use for free. The lending library will come with a toolkit that will list all available materials with instructions anyone can use on how to create their own pop-up traffic-calming demonstrations.

These lighter, quicker, cheaper tactics have already shown to be a catalyst for change within the City of St. Louis. The demonstrations have aided in creating new traffic-calming policies and the City of St. Louis has begun to use the traffic-calming lending library for community outreach.

These demonstrations are helping the City of St. Louis to create equitable places people love by bringing together planning and public health.
