Final answer:
Shared left turn lanes help manage busy street traffic and may need revisiting with an increase in traffic volume due to local developments or events. The introduction of a traffic signal at an intersection can enhance safety by regulating vehicle speed and improving pedestrian crossing conditions.
Step-by-step explanation:
The use of shared left turn lanes is a traffic management strategy that can be critical in maintaining flow and safety on busy streets. These lanes facilitate turning into businesses or side streets without obstructing through traffic.
However, their implementation is even more pertinent when considering factors like an increase in traffic volume due to nearby business growth or changes in local infrastructure like a new manufacturing plant, expansion of a strip mall, or altered traffic routing for events.
Moreover, the introduction of a traffic signal at a problematic intersection can regulate speeding vehicles and enhance pedestrian safety, allowing for safer crossing times, and directly addressing concerns such as vehicles disregarding the speed limit.
Shared left turn lanes are a feature on busy streets that allow drivers traveling in either direction to make left turns. These lanes are located in the center of the road and are designated for use by vehicles turning left. They help drivers turn into businesses in the middle of the block by providing a designated space for turning, separate from through traffic.
For example, if a driver needs to turn into a business located in the middle of the block, they can use the shared left turn lane to safely maneuver into the business entrance, without blocking the flow of traffic in either direction.
