What is the purpose of red truncation in transit systems?

Red truncation in transit systems is specifically aimed at minimizing delays for transit vehicles, such as buses and trams. This technique involves shortening the duration of red lights for these vehicles when they are approaching an intersection. By allowing transit vehicles to clear intersections more quickly, red truncation helps improve the overall efficiency and reliability of transit services. The primary goal is to enhance the flow of public transportation and encourage its use, reducing congestion and improving travel times for passengers.

In relation to the other options, increasing red light duration would not align with the goal of minimizing transit delays. Synchronizing with traffic lights might be relevant, but the main point of red truncation is to prioritize transit vehicles specifically, rather than synchronizing their movement with general traffic flow. Ensuring pedestrian safety is a critical concern at intersections but is not the primary focus of red truncation, which is designed to facilitate quicker transit vehicle passage rather than to increase safety for pedestrians.
