Final answer:
True, a complex intersection can indeed have multiple lanes with dedicated turning lanes and arrow signals, especially in high-traffic areas which may include nearby businesses, manufacturing plants, or significant pedestrian activity. Traffic signals play a crucial role in managing speed and ensuring pedestrian safety. High accident rates at such intersections underscore the need for these traffic control measures.
Step-by-step explanation:
True, complex intersections may contain multiple lanes, including five to six lanes, with various dedicated turning lanes, and incorporate arrow signals. The presence of strong traffic controls such as traffic signals becomes especially important in areas where traffic volume has increased significantly. Consequently, the installation of a traffic signal at such an intersection would consider the influx of vehicles from a nearby manufacturing plant, a 50% increase in businesses at a local strip mall, changes in traffic patterns due to college football games, and concerns over pedestrian safety. This complexity is typically addressed by traffic engineers to improve overall safety and traffic flow.
For pedestrians including college students who need to cross at these busy intersections, a traffic signal plays a vital role in their safety, allowing them to cross at appropriate and safer times. Speeding is also a concern, as vehicles often ignore posted speed limits, posing a risk not only to other drivers but also to pedestrians. Installing a traffic signal can enforce slower speeds, since drivers can't speed through a red light.
Lastly, the occurrence of accidents, sometimes with grave outcomes, further demonstrates the need for effective traffic control measures. Police reports indicating frequent accidents and even fatalities strengthen the case for a traffic signal, aiming to prevent such incidents and offer a regulated and safer environment for all road users.
