What are bus priority measures?
What are bus priority measures?
Bus priority measures aim to reduce journey times and improve the reliability of bus services. They include: segregation; traffic management; traffic signal control; and bus stop improvements. Bus priority measures are particularly effective wherever bus journey times and reliability are affected by traffic congestion.
How does transit signal priority work?
Transit Signal Priority (TSP) adjusts the timing of a traffic signal’s red and green cycles to reduce the amount of time a transit vehicle spends waiting at a red light. TSP works by making minor modifications to the traffic signal cycle or phasing in the presence of approaching transit vehicles.
How does a bus signal work?
When a Metrobus is stopped at an intersection, the new bus-only traffic signal displays a vertical bar while all other signals at the intersection are red, indicating only buses can proceed. After three seconds, a flashing triangle indicates that the priority signal for buses is about to end.
What is the difference between passive and active transit signal priority?
Passive priority strategies give priority to transit vehicles without the need for transit vehicle detection. Conversely, active priority strategies provide priority to transit vehicles after a transit vehicle is detected and priority conditions are met.
How wide should bus lane be?
Recommended. Bus lane width should be determined based on the available street space and the competing needs of bicyclists, pedestrians, and motorists. The minimum width of a curbside bus lane is 11 feet. The minimum width of an offset bus lane is 10 feet.
What is a TSP in transportation?
Transportation Safety Planning (TSP) is a comprehensive, system-wide, multimodal, proactive process that better integrates safety into surface transportation decision-making. Federal law requires that the State and Metropolitan transportation planning processes be consistent with Strategic Highway Safety Plans.
What is emergency vehicle preemption?
Emergency vehicle preemption (EVP) is designed to give emergency response vehicles a green light on their approach to a signalized intersection while providing a red light to conflicting approaches.
What is bus gate?
A bus gate is a short section of road which only buses and authorised vehicles can go through as shown by appropriate signage.
Do buses control traffic lights?
As a bus passes over one of the loops, a $75 transmitter mounted on its front sends an identifying signal to an equipment box that controls the traffic light at the next intersection. The signal is also sent to a central control center downtown, so the bus can be tracked in the computer system.
What is the difference between signal preemption and signal priority?
The difference between TSP and signal preemption is that signal priority modifies the normal signal operation process to better accommodate transit vehicles, while preemption interrupts the normal process for special events such as approaching train or responding fire engine.
What is bus width?
Bus width refers to the number of bits that can be sent to the CPU simultaneously, and bus speed refers to the number of times a group of bits can be sent each second. A bus cycle occurs every time data travels from memory to the CPU. Latency refers to the number of clock cycles needed to read a bit of information.
