State Farm sponsored lesson: "Road Design and Safety" is a PowerPoint for primary and secondary students that overviews safety on roadways and ways in which engineers incorporate safety when designing roads. It also highlights careers in road design and safety. Additionally, this lesson can be paired with a "Design your own 3D Model of Transportation Effectiveness and Roadway Safety" activity.

Road Design and Safety

  1. 1. Road Traffic Safety Road traffic safety is the process of reducing the risk of a person getting injured while using roads Engineers design roads to protect people and get people to their destination in a timely manner
  2. 2. Facts on Road Safety 2.35 million people are injured or disabled due to traffic crashes every year Correct use of seat belts reduces risk of injury or death by 61% Nearly 8,000 people are killed in crashes involving drivers ages 16-20 every year
  3. 3. What are some ways that engineers keep roads safe? Barriers Road design Speed limits Traffic lights and signs
  4. 4. What do barriers do? Separate oncoming traffic Prevents cars from veering off the road, and serious injuries Protects construction workers and pedestrians
  5. 5. Types of Barriers Concrete Barriers Traffic Cones/Guards Guard Rail Barriers Steel Cable Barrier
  6. 6. Road Designs Road and civil engineers design roads for specific areas Determine the vehicles that will pass through and how many lanes will be needed Design shoulders on side of roads – used to pull over during emergency
  7. 7. Speed Limits Sets maximum speed which vehicles can legally go Created to control flow of traffic Vehicle weight and stopping time put into consideration, as well as location
  8. 8. Traffic Lights and Signs Another device to help control traffic Traffic lights also help flow of traffic by stopping traffic from one direction to the next Signs advise drivers what to expect ahead in the roads and how to act while driving
  9. 9. What should you do in an emergency? Pull over to the side of the road, preferably off the road or on the shoulder Put on hazard lights and make other vehicles know you’re parked Get help by calling police or local services Exercise caution!

  11. 11. Civil Engineer Civil engineers are able to develop plans to create and design roads Planning involves estimating the costs of projects and the dates that projects may be finished
  12. 12. Transportation Engineer Determines speed limits and placements of signs along roads by forecasting traffic flow Ensures that the roads are safe, well- organized and cost-effective
  13. 13. Geotechnical Engineer Helps planning in creating safe roadways by testing if the area’s ground is suitable Surveys and maps geographic information and relays the information to civil engineers
  14. 14. State Patrol Enforces road safety laws such as speed limits and distracted driving Gives people tickets and warnings for not following laws
  15. 15. Construction Worker Builds and maintains roads to specific standards Uses heavy machinery to complete tasks
  16. 16. Activity Design your own 3D Model of Transportation Effectiveness and Roadway Safety First, use the grid paper to plan out your roadways Must include: ○ Barriers ○ Speed limits ○ Shoulders ○ Traffic signs ○ Multiple lanes Take your roadway plan and create a 3D Model with different roadway materials
