1 Describe a signalized intersection that you drive through

1. Describe a signalized intersection that you drive through on a regular basis and describe a characteristic that might be redesigned to improve traffic flow.

Solution

1)An intersection is a shared space that is used by more than one approach at a time.

2)A signalized intersection is one where the shared space is used alternatively by a fixed number of approaches for a pre defined time interval as per the phasing scheme used for the intersection.

3)Delay and queuing process are the main characteristics of such an intersection which help in analyzing and designing the intersection for a particular level of service.

4)Vehicle delay is the most important parameter used by transportation professionals in evaluating the performance of a signalized intersection.
