In this role, you will: Review and analyze roadway and traffic design plans for highways, streets, and intersections. Analyze as-built drawings, construction plans, and traffic control plans for compliance with contracts and engineering standards. Research and evaluate traffic conditions using traffic counts, speed studies, accident history data, and roadway characteristics. Determine safe and efficient traffic volumes based on roadway geometry and operating conditions. Assess sight distance, roadway alignment, pavement conditions, hazards, and work zone traffic control. Analyze traffic signal timing, phasing, maintenance, and intersection layout for operational performance and safety impacts. Determine whether roadway features or traffic control elements contributed to vehicle, pedestrian, or bicycle accidents. Review existing and proposed roadway signs, markings, and traffic control devices for compliance with standards. Analyze traffic signal timing, phasing, maintenance, and intersection layout for operational performance and safety impacts.
