Core Responsibilities

Primary Functions

Conduct systematic field inspections and functional tests of traffic signals, pedestrian signals, and related electronic control equipment to verify proper operation, timing, and compliance with MUTCD and local standards.
Proactively patrol assigned areas to inspect the condition, visibility, and placement of all traffic signs and pavement markings, identifying and documenting needs for repair, replacement, or upgrades.
Investigate, analyze, and respond to a wide range of inquiries and complaints from the public, law enforcement, and government officials regarding traffic safety issues, signal malfunctions, and signage requests.
Review and interpret complex civil engineering plans, traffic control plans (TCPs), and site development blueprints to ensure proposed construction and development activities adhere to all transportation and traffic regulations.
Perform comprehensive traffic engineering studies, including manual and automated traffic counts, vehicle speed studies, turning movement counts, and gap studies to collect data for analysis and decision-making.
Monitor active construction and utility work zones to enforce compliance with approved temporary traffic control plans, ensuring the safety of workers, pedestrians, and the traveling public.
Prepare detailed and accurate inspection reports, daily activity logs, investigation findings, and official correspondence using specialized software and standard office applications.
Respond promptly to traffic incidents, accidents, and signal-related emergencies to assess infrastructure damage, assist emergency services with traffic management, and initiate necessary repairs.
Maintain a precise digital and physical inventory of all traffic control assets, including signs, signals, poles, and markings, utilizing GIS and asset management systems.
Coordinate closely with internal maintenance crews, external contractors, and utility companies to schedule and oversee the repair, installation, and maintenance of traffic infrastructure.
Enforce municipal codes, ordinances, and state statutes related to traffic, parking, and the use of public rights-of-way, issuing notices or citations as authorized and required.
Perform specialized nighttime inspections to evaluate the retro-reflectivity of signs and pavement markings, ensuring they meet minimum visibility and safety standards for nighttime driving conditions.
Analyze intersection and roadway segments for sight distance obstructions, such as vegetation or illegal signage, and take appropriate action to mitigate potential hazards.
Assist senior staff and traffic engineers in the development and modification of traffic signal timing plans based on collected data, field observations, and traffic flow patterns.
Evaluate the justification and feasibility of requests for new traffic control devices, such as stop signs, crosswalks, or signals, by conducting thorough warrant analyses.
Document and report damage to public infrastructure caused by accidents or vandalism, collecting necessary information for police reports, insurance claims, and repair work orders.
Provide expert testimony in court proceedings or administrative hearings related to traffic citations, accident investigations, or code enforcement actions.
Issue and manage permits for temporary traffic control, street closures, and special events, reviewing applications to ensure safety and minimal disruption to the public.
Operate and maintain a variety of technical equipment, including traffic counters, signal diagnostic tools, GPS units, and distance measuring instruments.
Participate in pre-construction meetings with developers and contractors to provide expert input on traffic management requirements and potential impacts on the transportation network.

Secondary Functions

Respond to and analyze ad-hoc data requests from leadership and the public concerning traffic volumes, accident history, and signal performance.
Contribute field-level insights and practical knowledge to the development of the organization's long-term transportation master plan and capital improvement strategy.
Collaborate with engineering and planning departments to translate observed traffic issues and public needs into actionable engineering and infrastructure projects.
Participate actively in departmental safety meetings, team planning sessions, and cross-functional project reviews to foster a collaborative and safety-conscious work environment.
