What are the main functions of channelization at an at-grade intersection?
What will be an ideal response?
Channelization is intended to separate conflicting traffic movements into
defined paths to facilitate the safe and orderly movements of both vehicles and
pedestrians. This can accomplish many things, including:
? Direct the paths of vehicles so that not more than two paths cross at one point
? Control the merging, diverging, or crossing angle of vehicles
? Decrease vehicle wander and the area of conflict among vehicles by reducing
the amount of paved area
? Provide a clear indication of the proper path for different movements
? Give priority to the predominant movements
? Provide pedestrian refuge
? Provide separate storage lanes for turning vehicles, thereby creating space
away from the path of through vehicles for turning vehicles to wait
? Provide space for traffic control devices so that they can be readily seen
? Control prohibited turns
? Separate different traffic movements at signalized intersections with multiplephase
signals

A set of measurable parameters with values specific to the product that together define the product is called the specifications. These parameters are either physical properties of the product or the capabilities of the product. Log on to the Internet to extract the specifications of a product and to identify these two classes of specifications.
