Imagining Tomorrow: What Causes Traffic?



What causes traffic?


When many people must go to the same place at the same time, there are more cars on the road. This usually happens in the morning and in the evening when people are going to school and work or coming back home.

Traffic engineers figure out which roads have the most people on them and then design the roads and traffic signals to keep people moving in their cars. Traffic engineers also make sure the roads are safe for people walking or riding their bicycle so we can have a safer community!

Traffic engineers help you travel safely and easily to all the places you work, live, and play.

Learn more about the world of engineering with your children by watching our previous Imagining Tomorrow videos, where you can find out what an engineer is and where our drinking water comes from. For more information about what Horrocks Engineers can do, visit our services page today.
