About Parsons Corporation

Parsons Corporation fosters an innovative culture that supports professional growth and achievement. As a global leader in engineering, construction, technical, and management services, we are committed to delivering complex solutions across various sectors.

The Opportunity

We are seeking a Traffic Engineer – Synchro Specialist to join our team in Riyadh, Saudi Arabia. This is a full-time position requiring 5-10 years of relevant experience in traffic engineering and Synchro/SimTraffic modeling.

Role Purpose

The specialist will be responsible for developing, calibrating, and applying Synchro/SimTraffic traffic operations models. This role supports the testing, comparison, and optimization of intersection and corridor improvement strategies across Riyadh. The position involves converting field data and existing signal information into reliable operational models to diagnose deficiencies and evaluate various timing, phasing, lane-use, geometric, and coordination improvements before field implementation.

Key Responsibilities

Develop Synchro models for signalized and unsignalized intersections and coordinated arterial corridors using approved traffic counts, roadway geometry, signal timing, and field-condition information.
Review and code model parameters including lane configurations, turn movements, saturation flows, heavy vehicles, grades, storage lengths, pedestrian phases, phasing sequences, timings, and offsets.
Calibrate and validate models utilizing observed queues, travel times, field saturation conditions, cycle observations, and other available operational evidence.
Utilize Synchro and SimTraffic to identify operational deficiencies such as bottlenecks, split failures, queue spillback, progression issues, capacity constraints, and potential network interactions.
Develop and test alternative timing plans, phasing strategies, cycle lengths, splits, offsets, lane-use changes, turn restrictions, channelization, and minor geometric improvements.
Optimize coordinated corridor timing plans to enhance progression, reduce stops and delay, and manage queues across multiple intersections.
Compare alternatives using appropriate measures of effectiveness, including delay, level of service, queues, stops, travel time, v/c ratio, throughput, and progression quality.
Prepare clear before-and-after model summaries, exhibits, tables, timing sheets, and technical narratives to support recommended improvements.
Collaborate with Traffic Signal Operations Engineers to convert approved model recommendations into implementable controller timing plans and field test strategies.
Support the development of quick-win and longer-term corridor improvement programs by quantifying expected operational benefits and identifying constraints requiring further design.
Maintain organized model files, version history, assumptions, input data, calibration notes, and model-review records.
Conduct sensitivity testing where traffic demand, detector operation, signal control, or field conditions introduce uncertainty in expected results.
Support traffic impact assessments, corridor studies, construction traffic analyses, and special-event planning where Synchro modeling is applicable.
Participate in technical reviews with senior traffic engineers and revise models based on quality-review comments and field verification.
Contribute to standardized Synchro modeling procedures, templates, quality checks, and documentation practices for the project.

Qualifications and Experience

Candidates for this role should possess 5-10 years of experience in traffic engineering, with a strong focus on traffic operations modeling. Proficiency in Synchro and SimTraffic software is essential, alongside the ability to interpret field data and apply it to complex traffic models. A solid understanding of traffic signal operations, geometric design principles, and performance measures is required.
