A traffic signal or intelligent transportation system (ITS) technician is responsible for the installation, maintenance, and/or repair of ITS and traffic signal systems including traffic signal cabinets, loop detection systems, and traffic signal electronics. A traffic signal or ITS technician might also assist with the development of traffic studies and design plans such as for ITS infrastructure, traffic signals, signing, pavement marking, construction sequencing, and traffic control plans. The technician may troubleshoot ITS and traffic signal equipment and make recommendations to repair or resolve any issues in a given system. These technicians may also be responsible for the maintenance of spare equipment and parts, including inventory management and documentation. Relevant technology includes CCTV systems, dynamic message signs, travel time readers, vehicle detection systems, and fiber optics and wireless systems. A traffic signal or ITS technician should ensure that traffic signal installation and related activities are conducted in compliance with applicable traffic control device regulations, standards, and specifications.
Analytical, Mathematical, or Problem-solving Skills
Civil Engineer (Transit)
A civil transit engineer will develop, analyze, inspect, and/or design transit infrastructure, transit stations, buildings, underground structures, or elevated structures or bridges. A civil transit engineer will often perform field surveys, develop transit plans, secure permitting for transit infrastructure, prepare engineering design reports, prepare constructions plans, respond to structural emergencies, and/or prepare contract documents for rail or transit engineering projects. A civil transit engineer will often participate in on-site reviews of project locations to monitor progress and ensure conformance to design specifications and safety standards. A civil transit engineer may also perform transit/traffic analysis, transportation operations, ITS and safety concepts, and pedestrian improvement plans. A civil transit engineer may utilize AutoCAD or Civil 3D software in plans for transit facility designs, diagrams, or models, and to execute engineering tasks. A civil transit engineer will coordinate with local officials to ensure compliance of design in accordance with transit agency standards and specifications. A civil transit engineer with project management duties will also develop and manage a transit project’s design scope, proposal, schedule, and resource estimates, as well as coordinate efforts of the design team or supervises related support staff.
Industrial engineers and operations research or modeling analysts working in transportation operations use advanced mathematical and analytical methods to analyze and solve complex problems, assess risk, and provide a data-driven approach to decision-making. They might be involved in numerous types of projects including process improvement plans, warehouse and labor management, capital projects, inventory and equipment planning, cost saving initiatives, or logistics process design. Utilizing industrial engineering skills inherent in process flow analysis, operational project planning, efficiency or process improvement studies, statistical and mapping analysis, and time and motion studies, the industrial engineer or operations analyst will be involved in planning and designing new transportation operations, supporting existing operations, and developing comprehensive supply chain solutions.
An operations planner is involved in managing complex projects and systems and conducting many types of transportation planning analyses or studies including corridor planning, traffic operations planning, multi-modal or transit-oriented projects, or freight operations planning. An operations planner may perform transportation development planning, system and route performance analyses, operational assessments, transportation project feasibility studies, and market research for transportation projects. An operations planner might also perform field review, field data collection, site and infrastructure assessments, project finance and governance, grant initiatives, public or stakeholder outreach, and other on-site project support. An operations planner may complete assessments using analytical tools such as GIS to evaluate data, identify trends, and develop any project-related documentation.
Diesel mechanics or technicians are responsible for performing mechanical repairs and preventative maintenance on fleet vehicles and heavy equipment in transit and freight. They are fluent in the maintenance and repair of mechanical, electrical, hydraulic, and diesel systems. Diesel mechanics or technicians also complete repair or service reporting, order and inventory necessary parts, fabricate necessary parts or equipment, develop and execute service or repair processes, and provide road call or emergency service calls.
