Final answer:
Advance warning signs are used to alert drivers of upcoming railroad crossings, enhancing road safety. Tollbooth stations use detection systems to prepare for vehicles, and traffic signals at intersections improve pedestrian safety by controlling crossing times and vehicle speeds.
Step-by-step explanation:
Advance warning signs for railway tracks are indeed used to alert drivers to the presence of a railroad crossing ahead. These signs are crucial for road safety as they inform drivers to be prepared to stop if there is a train approaching. Tollbooth stations may have a piece of wire in the pavement to detect the presence of a vehicle and prepare the tolling system. Pedestrian safety is also a significant concern near railways and roads; traffic signals at intersections can greatly enhance the safety for pedestrians by allowing them to cross at designated times, as they provide controlled opportunities for crossing and can slow down speeding vehicles. Furthermore, standing too close to railroad tracks can be dangerous because the atmospheric pressure changes caused by a rapidly moving train can potentially pull a person towards the train.
