Answer :
Final answer:
To ensure safety, it's illegal to park within five meters of a fire hydrant, six meters of a crosswalk or intersection and stop sign or traffic light, and fifteen meters from the nearest rail crossing. Pedestrian safety rules dictate the need to cross the road with a sufficient safety buffer, factoring in the speed limit and distance from approaching vehicles.
Explanation:
It's illegal to park within specific distances of various road infrastructure to ensure safety and traffic flow. A common rule is that parking is not allowed within five metres of a fire hydrant, six metres of a crosswalk or intersection, and six metres of a stop sign or traffic light. Additionally, parking is typically restricted within fifteen metres of the nearest rail or railway crossing to provide clear visibility for train operators and motorists.
These regulations help pedestrians cross roads safely, like in the example where pedestrian safety at a university campus is enhanced through a traffic signal. When it comes to pedestrian crossing times, if a car is traveling at a city speed limit of 60 km/h, a pedestrian should ensure they can walk at least 4 meters before the car reaches them, which is further than the width of an average car.
Using Bridget's observation that it takes cars 3 seconds to cover 50 meters, a reasonable safety buffer for crossing the street could be calculated, taking into account the speed of the vehicles and the distance required for a pedestrian to cross safely.
