• Monitor signalized intersections and coordinated corridors using central signal systems, CCTV, detector information, dashboards, and field observations.
• Review phasing sequences, splits, cycle lengths, offsets, clearance intervals, recalls, detector settings, and controller parameters.
• Identify operational problems affecting intersection capacity, progression, queue performance, or traffic reliability.
• Develop approved signal timing adjustments for isolated intersections and coordinated arterial corridors.
• Implement signal timing changes through established system and change-control procedures.
• Conduct before-and-after evaluations to determine whether implemented changes improve delay, queues, throughput, travel time, and progression.
• Confirm that timing adjustments do not create unacceptable secondary impacts at adjacent intersections or movements.
• Support green-wave and corridor progression optimization by reviewing offsets, travel times, platoon movement, and coordination plans.
• Identify split failures, excessive queues, wasted green time, poor progression, recurring congestion, and inefficient phase utilization.
• Distinguish signal timing problems from detector failures, communication faults, controller issues, geometric constraints, or abnormal traffic demand.
• Use Automated Traffic Signal Performance Measures where available to evaluate arrivals on green, arrivals on red, split performance, phase utilization, and detector activity.
• Analyze high-resolution controller data to support more detailed assessment of signal performance.
• Coordinate with field maintenance teams when detector faults, cabinet problems, communication failures, or controller defects affect operations.
• Support adaptive signal control by checking input data, controller status, detection performance, and abnormal system behavior.
• Escalate adaptive control issues requiring specialist intervention.
• Assist with implementation and monitoring of emergency vehicle preemption strategies.
• Support transit signal priority and other approved priority treatments.
• Assist with signal timing plans for major events, incidents, construction activities, and unusual traffic conditions.
• Monitor queue-management strategies and recommend operational adjustments where recurrent congestion is identified.
• Maintain accurate records of signal timing changes, operational observations, approvals, intervention reasons, and measured results.
• Prepare shift handover information so traffic operations decisions remain transparent and traceable.
• Conduct field observations during peak traffic periods to validate central system findings.
• Identify field conditions that may not be apparent through CCTV or central monitoring systems.
• Support development of traffic signal operating procedures, standard timing practices, corridor playbooks, and performance thresholds.
• Help improve TCC documentation covering signal operations, intervention procedures, and recurring problem locations.
• Provide technical guidance to TCC operators regarding basic controller behavior and traffic signal operations.
• Share operational knowledge with junior traffic engineers and project personnel.
• Participate in regular traffic signal performance reviews.
• Recommend intersections and corridors requiring detailed engineering study, geometric modification, or specialist analysis.
• Track recurring congestion and operational deficiencies to identify long-term improvement priorities.
• Coordinate with senior engineers on timing strategies requiring broader corridor or network-level analysis.
• Support technical reporting on signal performance, timing interventions, congestion trends, and operational outcomes.
• Maintain disciplined change records to ensure signal adjustments can be reviewed, validated, or reversed when necessary.
• Promote data-driven decision-making within day-to-day traffic signal operations.
