What is the primary purpose of traffic calming measures?

1. To increase the number of lanes on a road

2. To reduce traffic speeds and cut-through traffic

3. To enhance vehicle flow through intersections

4. To promote commercial traffic in residential areas

The correct answer is: To reduce traffic speeds and cut-through traffic

The primary purpose of traffic calming measures is to reduce traffic speeds and cut-through traffic. These measures are designed to create a safer and more comfortable environment for pedestrians, cyclists, and residents in areas where excessive speed and volume of vehicle traffic can lead to hazards. Traffic calming techniques can include physical alterations to the roadway, such as speed bumps, raised crosswalks, curb extensions, and chicanes, which physically slow down vehicles and encourage drivers to navigate more carefully. By focusing on reducing speed, traffic calming not only enhances safety but also improves the overall quality of life in residential neighborhoods, making them more inviting for walking and biking. Furthermore, these measures can discourage non-local traffic from using residential streets as shortcuts, thus maintaining the integrity of the community and promoting safer interactions among all road users.
