Final answer:
To avoid collisions in city traffic, being vigilant and having a traffic signal at high-risk intersections are key. Traffic signals control vehicle speeds and enhance pedestrian safety by providing structured crossing times.
Step-by-step explanation:
Often, your only chance to avoid a collision in city traffic is to be alert and aware of your surroundings, especially at dangerous intersections where vehicles speed through without heed to the posted speed limits. Installing a traffic signal at such intersections can significantly reduce the risk of accidents. This intervention forces vehicles to slow down and provides clear rules for right-of-way, decreasing the likelihood of a collision. It also improves pedestrian safety, as individuals, including many students, can cross at appropriate and predictable times without having to dodge in and out of traffic.
