Traffic Engineer – Synchro Specialist

About the role

Parsons is seeking a Traffic Engineer – Synchro Specialist to develop, calibrate, and apply Synchro/SimTraffic models for intersection and corridor improvements in Riyadh. You will translate field data into operational models, diagnose deficiencies, and evaluate timing, phasing, and geometric enhancements before implementation.

Key responsibilities

• Build and calibrate Synchro models for signalized and unsignalized intersections and coordinated arterial corridors using traffic counts, geometry, and signal timing data.
• Identify operational deficiencies such as bottlenecks, queue spillback, and progression issues, and develop alternative timing plans, phasing strategies, and lane‑use changes.
• Validate models with observed queues, travel times, and saturation conditions, and prepare before‑and‑after summaries, technical narratives, and timing sheets.
• Collaborate with Traffic Signal Operations Engineers to convert model recommendations into field‑ready controller timing plans.

Required profile

• Bachelor’s degree in Civil, Transportation, or Traffic Engineering.
• At least 4 years of traffic engineering experience with hands‑on use of Synchro and SimTraffic.
• Strong understanding of signalized intersection operations, phasing, coordination, and level‑of‑service analysis.

Required skills

• Proficiency with Synchro and SimTraffic modeling software.
• Advanced use of Microsoft Excel, Word, and PowerPoint for analysis and reporting.
• Familiarity with HCM principles applied within Synchro.
