Three Ways Connected Vehicle Technology Creates Safer Roads (For More Than Just Drivers!)

May 27, 2020
For decades, road safety has been a shared concern for the public, health organizations and governments—namely because, according to the CDC, motor vehicle crashes are a leading cause of death in the United States. And sure, you could say that most accidents stem from driver error. But the most effective option to realistically predict and prevent crashes and injuries is through planning, management and evidence-based interventions that can reduce potential points of impact. This post will break down some of the ways connected vehicles and other smart technology are helping to do just that—using infrastructure improvements to increase safety, walkability, mobility and quality of life.

Getting Smarter

Smart technology has been a part of public infrastructure for years, whether or not you may have noticed it. From highway electronic messaging, pedestrian crosswalk buttons, cruise control systems, and blind spot detection, advances in roadway technology have made a real difference for everyone on the road. Forward Collision Warnings with Automatic Emergency Braking (both technology-based safety systems) reduce rear-end crashes by 39%1. In the Town Center Community Improvement District (CID), 47 intersections use SCATS, an adaptive traffic control system that has assisted with traffic flow on roadways and at interstate interchanges.

As with any technology, smart roadway practices are evolving rapidly.  They have become a living, interactive system connecting vehicles, traffic signals, mobile devices and more. Using wireless communications like 5G networks, connected vehicle technology monitors real-time roadway information to reduce crashes, protect walkers and tone down congestion. It has the potential to transform transportation across private vehicles, emergency vehicles, freight, transit and pedestrians.

In the coming years, we will see smart tech improve road safety in many ways. Here are three prominent examples:

Emergency Vehicle Preemption

With emergency vehicle preemption (EVP), emergency response vehicles like ambulances and fire trucks can trigger traffic signals to allow them to move through a crowded intersection. The emergency vehicles use radios and sensors to adjust intersection lights, which can improve response times, ensure other drivers are where they need to be, and increase their ability to save lives.2

Transit Signal Priority

Transit Signal Priority works in much the same way as EVP to reduce traffic congestion. Municipal transit like buses, trams and trolleys can coordinate with and control traffic signals, which can make their schedules more reliable for users while freeing up the roads for other vehicles.

Pedestrian in Crosswalk Detection

With Crosswalk Detection in vehicles, cars will be able to cut down drivers’ blind spots by sensing if there is a person in the crosswalk. This technology is a significant upgrade for those who enjoy traveling on foot. These vulnerable road users (other at-risk travelers include cyclists and motorcyclists) account for more than half of all road traffic deaths.

Timing is Everything

Now that we’ve introduced you to a few types of connected vehicle technology, you may be wondering what you will actually see on the roads. The truth is, integrated technology is already here.

Auto manufacturers are getting ready to produce new connected safety systems in their upcoming models.3 Also, municipalities across metro Atlanta are preparing for 5G networks and approving funding for signal light enhancements, so Emergency Vehicle Preemption and Transit Signal Priority will be more beneficial. These are prime circumstances to implement the first smart corridor in Cobb County.

The Town Center CID is dedicated to improving safety, walkability, mobility and quality of life, which are the central concerns of our stakeholders. Therefore, we presented Cobb County and the Atlanta Regional Commission with an idea for a connected technology project along the Chastain Road corridor, which would see the most significant impact from smart upgrades. Why?

Chastain Road has:

More Activity

  • Dining
  • Retail
  • Student housing
  • Multi-family residences
  • Hotels
  • Stadium
  • Industrial
  • International Airport
  • University
  • Office parks

Diverse Travelers

  • Access to two major interstates
  • Pedestrians and cyclists
  • University shuttles
  • 18-wheelers
  • Local transit stops
The ongoing study of Chastain Road is exploring how Emergency Vehicle Preemption, Transit Vehicle Priority, Pedestrian Detection and more could all find a place along the active corridor.
Every day, the CID is learning more about the real impact of smart technology for all road users. In 2014, the U.S. Department of Transportation estimated that advanced vehicle connectivity could reduce road accidents by more than 80%.4 Now, we have arrived at a prime opportunity to leverage smart technology to reach our goals for the district. With proper planning and key partnerships, smart corridors will help the CID create a safer, less congested, more walkable environment.
