TRAM · SIGNAL PRIORITY
Tram Signal Priority
Control System.
Coordinates intersection traffic flow as trams approach.
Connects onboard and wayside communications, signal-priority control and integrated monitoring.
CONNECTED SIGNAL CONTROL
From vehicle approach,
to intersection passage.
A signal-priority control system connects tram location and approach information with road signals. Onboard and wayside communications, intersection signal integration, integrated monitoring and simulation are configured together to coordinate tram operations and road traffic.
Signal-priority control
Designs request, assessment, application and release workflows according to signal operating requirements
Integrated monitoring and analysis
Review operational and device status, signal-processing records and results for each scenario
HOW IT WORKS
Approach, assessment, control and return to normal.
Connect the complete operational workflow.
- 01
Collect approach information
Link vehicle position, direction, speed and station departure information to identify the target intersection and estimated arrival time.
- 02
Assess priority requests
Configure assessments of whether and when to apply signal priority using estimated arrivals, service delays and intersection signal status.
- 03
Integrate intersection signals
Apply approved policies, including green extension and early green, within pedestrian and vehicle safety intervals and control limits.
- 04
Check passage and return to normal
Release the priority request after the vehicle passes and check normal signal operation and processing results. Records are available through monitoring.
PRIORITY STRATEGY
Signal priority for site requirements
Green extension
Review the time needed for passage and extend green time in the tram’s direction within permitted limits.
Early green
Start green earlier in the tram’s direction after allowing minimum green time for conflicting traffic and pedestrian safety intervals.
Conditional priority
Design priority conditions and request-processing order using service delays, headways and road congestion.
OPERATING CONDITIONS
Operational conditions designed together
Pedestrians and conflicting traffic
Define the permitted control scope using pedestrian crossing times, vehicle conflicts and vehicles remaining in the intersection.
Communications and equipment fault response
Design procedures to suspend priority requests and maintain or restore existing signal operations when information is delayed, communications are lost or equipment fails.
Authentication, permissions and records
Link device authentication, operator permissions and policy-change and control records to communications security and audit processes.
SYSTEM CONFIGURATION
Vehicles, field equipment and control centers,
within one operational framework.
Design communications, control and monitoring integration for existing signal equipment and control-center environments.
01 / ON-BOARD
Onboard communications and operational information
Connect vehicle interfaces and onboard terminals to transmit position, direction and operational status to wayside systems.
02 / WAYSIDE
Wayside communications and intersection integration
Exchange priority requests, signal status and passage information through wayside wireless networks and site integration devices.
03 / PRIORITY SERVER
Signal-priority policy and request management
Manage application conditions and request validity periods for each intersection, with request, approval, release and exception-handling workflows.
04 / CONTROL CENTER
Integrated monitoring and operational records
Review vehicle, intersection and device status together, linking alerts, faults and signal-processing records to operational tasks.

BEFORE YOU START
Common questions before implementation.
How does it integrate with existing road signals?
Review each intersection’s controller and control-center environment, then design the integration scope around approved policies and safety intervals.
Do the simulators control site signals?
The simulators provided on this website are analysis interfaces for comparing operating and signal conditions. They are separate from live site control.
Tell us about the application environment and existing equipment so we can review the configuration you need.
