Final answer:
The statement that most intersections have traffic control devices is true as they are essential for managing traffic and improving safety. The installation of a traffic signal is often due to factors like high accident rates, the need for speed control, increased pedestrian traffic, and growing traffic volumes due to nearby developments.
Step-by-step explanation:
The statement "Most intersections do have traffic control devices" is generally true. Traffic control devices are critical for ensuring the orderly flow of vehicles and pedestrian traffic and improving safety at intersections. There are several reasons to support the installation of a traffic signal at an intersection:
- Reduction of vehicles speeding through the intersection and adherence to the posted speed limit.
- Improving pedestrian safety, especially around campuses where students frequently cross.
- A significant increase in the number of accidents, often a key factor in the decision to install a traffic signal.
- Increased traffic flow due to nearby developments such as manufacturing plants and businesses, and changes in traffic patterns for events.
Accordingly, traffic signals play a vital role in managing traffic, reducing accidents, and safeguarding pedestrians at busy intersections.
