18. Traffic Intersections

18. Traffic Intersections

Traffic intersections represent complex locations on highways, characterized by various conflicts among vehicles and pedestrians. The chapter discusses the significance of intersection control methods, which can vary from passive to active control, based on traffic volume and road geometry. It also outlines different types of intersections and their control strategies aimed at enhancing safety and efficiency.

What we have learnt

  • Traffic intersections are areas where multiple roads converge, leading to potential conflicts.
  • Intersection control can be achieved through passive, semi, or active methods depending on traffic conditions.
  • Different types of intersections, including at-grade and grade-separated, serve distinct operational needs and safety considerations.

Key Concepts

-- Intersection Control
Methods used to manage the movement of vehicles and pedestrians at traffic intersections.
-- Passive Control
Intersection control relying on basic traffic rules and signs, with minimal intervention from authorities.
-- Active Control
Intersection control where traffic movements are fully regulated by traffic signals or agencies.
-- GradeSeparated Intersection
Intersections allowing traffic to cross at different elevations to reduce conflicts.
-- Channelization
The use of physical structures, such as islands and markings, to direct traffic flow and improve safety.
