Traffic Signal Systems Expert

Job Summary

Parsons seeks a Traffic Signal Systems Expert to provide senior technical leadership for the assessment, planning, design, optimization, integration, operation, and performance monitoring of advanced traffic signal systems supporting a major urban traffic management program in Riyadh.

Responsibilities

• Lead technical assessments of existing traffic signal systems, including controller hardware, cabinet configurations, detection systems, communications, and central-system interfaces.
• Provide expert direction on adaptive signal control strategies, including system configuration, operating parameters, corridor progression, and congestion response.
• Review and optimize traffic signal timing plans, phasing sequences, cycle lengths, offsets, splits, and pedestrian timings.
• Evaluate the performance of multiple signal control platforms and advise on practical application, limitations, and integration needs.
• Lead development of technical standards, guidelines, procedures, and checklists for traffic signal design, controller programming, and field commissioning.
• Diagnose recurring signal operations issues using field observations, controller logs, detector data, and performance measures.
• Define requirements for Automated Traffic Signal Performance Measures (ATSPM), high-resolution controller data, dashboards, and reporting tools.
• Lead technical workshops with agency staff, vendors, contractors, and operators to resolve signal system issues and establish consistent operating practices.

Must haves

• Bachelor’s degree in Civil Engineering, Transportation Engineering, Electrical Engineering, Systems Engineering, or closely related field.
• 15+ years of specialized, progressive experience in traffic signal systems planning, design, implementation, operations, optimization, and performance management for transportation agencies or major transport owners/operators.
• Advanced knowledge of adaptive signal systems, including adaptive control principles, detector dependency, progression logic, and queue management.
• Demonstrated experience working with multiple signal control platforms, central traffic signal systems, and field device ecosystems.
• Strong hands-on experience with signal timing and operations, including actuated control, coordinated control, time-of-day plans, and controller parameter settings.
• Strong understanding of traffic signal controllers, cabinets, detection technologies, communications networks, and field troubleshooting practices.

Nice to haves

• Prior experience supporting Gulf region transportation agencies or large metropolitan transport authorities on traffic signal systems.
• Practical experience with major adaptive or central signal platforms such as SCOOT, SCATS, TransSuite, KLD, Siemens/Yunex, Econolite, or comparable systems.
• Experience with ATSPM implementation, high-resolution event data, and signal performance dashboards.
• Arabic language skills.
