Correct Answer: Overhead lane signals
Explanation:
Reversible lanes are specialized traffic lanes that change direction at different times of the day to help manage traffic flow, especially during rush hours. These lanes are commonly found on roads or bridges that experience heavy congestion during peak travel times. To ensure safety and efficiency, reversible lanes are marked with unique signs, signals, and markings, most notably overhead lane signals.
Overhead lane signals are electronic signs placed above each lane, often on gantries or cantilever structures. These signals use a combination of red Xs, green arrows, or yellow arrows to indicate whether a driver may use a lane and in which direction. For example:
- A green arrow means the lane is open in your direction.
- A red X means the lane is closed or is being used by traffic moving in the opposite direction.
- A yellow arrow or flashing signals typically warn drivers that the lane is about to change direction or that caution is advised.
These signals are crucial for reversible lanes because they allow for dynamic traffic control without the need for physical barriers. This helps maximize road capacity during different times of the day—like using more lanes for inbound traffic in the morning and outbound traffic in the evening.
In addition to overhead signals, reversible lanes may include pavement markings (such as double dashed lines) and traffic signs that provide operational rules, time schedules, and warnings. These help drivers understand when and how the lanes operate, reducing confusion and preventing accidents.
Overall, overhead lane signals play a key role in safely managing reversible lanes. Drivers must pay close attention to these signals and follow their indications to avoid entering a lane traveling in the opposite direction, which could lead to serious collisions.
