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.
