As the Clean Air Partnership works to encourage activities that reduce emissions, we continue to spotlight organizations in the St. Louis region that share our passion. With transportation being one of the largest contributors to air pollution, the efforts carried out by the Missouri Department of Transportation (MoDOT) are crucial in championing clean air.
MoDOT oversees a total of 33,856 miles of roadway throughout the state and, while commuting by automobile is necessary for many, MoDOT recognizes the importance of keeping congestion-related emissions at a minimum. Considering idling vehicles emit 20 times more pollution than a car traveling 30 miles per hour, alleviating congestion that causes stop-and-go traffic is key in promoting cleaner air.
Here is a look at several of the initiatives MoDOT has implemented to help keep traffic flowing, decrease emissions and clear the region’s air:
- Gateway Guide – This initiative combines several tools to provide motorists with real-time traffic updates. Traffic sensors alongside the road provide information on upcoming traffic speeds and volumes. MoDOT utilizes over 100 Dynamic Message Signs across the state which are permanent message boards located along state highways used to broadcast information regarding travel times, interstate closures, vehicle crashes and congestion. The @StLouisTraffic Twitter feed shares real-time information on closed lanes and roads. Closed-circuit cameras positioned throughout the region also provide real-time footage of area highways. These cameras provide video to help direct emergency response forces to quickly and safely address incidents. More importantly, the camera footage is streamed on Gateway Guide. MoDOT’s intent is that motorists will use this information to take alternate routes when traffic is heavy. By shifting traffic flow in various directions, congestion can be alleviated or avoided, ultimately reducing vehicle emissions.
- Ozone Information – During the ozone forecasting season, MoDOT operates eight portable message boards alongside roadways in the St. Louis region. These, along with the Dynamic Message Signs, present the daily ozone forecast and often provide motorists with air-friendly tips. For example, when the air quality is poor, the message board not only notifies motorists of the red state of the air, but it might also encourage motorists to avoid filling up with gasoline until after 7 p.m., to help prevent the development of ground-level ozone. These boards have the potential to reach more than half a million travelers in just one day and encourage the community to take part in activities that keep the air cleaner.
- Modification of Daily and Internal Operations – When the air quality is predicted to be poor, MoDOT works especially hard to alleviate congestion. This means halting routine maintenance operations on state highways that might create congestion and vehicle idling when the air quality is red. MoDOT also encourages their staff to use alternative forms of transportation and has a carpooling program in place for employees to team up to share the ride. These modifications further help to reduce pollution and improve the quality of the air we breathe.
