Study Notes
Intersections
- Intersections are points where multiple roads converge, posing a higher risk for accidents due to crossing vehicle paths.
- Statistics indicate that collisions at intersections, driveways, and highway ramps rank as the second most frequent type of traffic accidents.
Controlled Intersection
- A controlled intersection uses signs or traffic signals to manage traffic flow effectively, enhancing safety.
Traffic Signal
- Traffic signals are essential road infrastructure that regulates the movement of vehicles, cyclists, and pedestrians at intersections.
- They can be configured in either vertical or horizontal arrangements.
Yield Sign
- Yield signs at intersections require vehicles to slow down and give way to oncoming traffic, prioritizing flow from certain directions.
Stop Sign
- Stop signs mandate that vehicles come to a complete stop before yielding to cross traffic at intersections.
- In a four-way stop, all directions must stop, and the first vehicle to arrive has the right of way.
Uncontrolled Intersection
- Uncontrolled intersections are found in low-traffic areas where additional traffic control devices are unnecessary, relying on right-of-way rules for safe navigation.
- Common examples include highway interchanges and roundabouts.
Highway Interchange
- Interchanges structure highways at different levels with connecting roads, allowing uninterrupted traffic flow without stopping.
- This design minimizes congestion and facilitates smooth transitions between highways, with popular types including directional, cloverleaf, diamond, and trumpet interchanges.
Roundabout
- Roundabouts are a form of uncontrolled intersection where traffic moves around a central island.
- Vehicles entering must yield to those already circulating, and drivers should always watch for pedestrians and cyclists.
Road Signs at Intersections
- Traffic signs can be positioned either directly at or before an intersection, with warning signs typically placed in advance and regulatory signs at the intersection itself.
