Core Responsibilities

Primary Functions

Conduct comprehensive traffic analysis and forecasting using industry-standard modeling software (like Vissim, Synchro, and HCS) to predict future traffic patterns and assess the performance of roadway networks.
Develop detailed geometric designs for a wide range of transportation infrastructure, including highways, interchanges, urban arterials, intersections, and multi-modal corridors.
Prepare and manage the production of high-quality technical reports, Traffic Impact Studies (TIS), and feasibility studies to support planning, design, and regulatory approval processes.
Create precise construction plans, technical specifications, and detailed cost estimates for transportation projects, ensuring they are ready for bidding and implementation.
Ensure all designs and plans rigorously adhere to federal, state, and local standards and regulations, including guidelines from AASHTO, MUTCD, and relevant DOTs.
Lead and participate in field investigations and data collection efforts, including traffic counts, travel time studies, and site reconnaissance, to gather the essential data needed for analysis and design.
Evaluate and design traffic control measures, such as traffic signals, pavement markings, and signage, to enhance safety and optimize traffic flow for all road users.
Formulate and assess comprehensive transportation plans and policies aimed at improving system-wide safety, reducing congestion, and promoting sustainable travel options like public transit, cycling, and walking.
Utilize advanced CAD and GIS software (such as AutoCAD Civil 3D, MicroStation, and ArcGIS) to develop intricate designs and perform sophisticated spatial analysis of transportation networks.
Design temporary traffic control and maintenance of traffic (MOT) plans for construction zones to ensure the safety of workers, drivers, and pedestrians during project implementation.
Analyze and interpret large, complex datasets related to traffic volumes, accident statistics, and public transit ridership to identify trends and inform evidence-based decision-making.
Collaborate effectively within multidisciplinary project teams that include urban planners, surveyors, environmental scientists, and structural engineers to deliver holistic and integrated project outcomes.
Communicate complex technical information clearly and persuasively by presenting project findings, design concepts, and recommendations to clients, public agencies, and community stakeholders.
Review site development plans submitted by private developers to assess their potential impact on the existing transportation network and recommend necessary mitigation measures.
Develop optimized traffic signal timing and coordination plans for arterial corridors to minimize delays, reduce fuel consumption, and improve the overall travel experience.
Research and evaluate the feasibility and potential impacts of emerging transportation technologies, including connected and autonomous vehicles (CAV), smart city initiatives, and advanced traffic management systems.
Assist in preparing grant applications and funding proposals to secure the financial resources required for critical transportation improvement projects.
Perform safety audits and analyses of existing roadways to identify high-risk locations and develop countermeasures to reduce crashes and improve overall road safety.

Secondary Functions

Provide mentorship and technical guidance to junior engineers, designers, and technicians, fostering their professional growth and development.
Actively participate in professional organizations like ITE or ASCE, staying current with the latest industry research, trends, and best practices.
Support ad-hoc data requests and perform exploratory data analysis to uncover insights into mobility patterns and transportation system performance.
Contribute to the organization's broader data and mobility strategy, helping to shape how data is collected, managed, and utilized for planning and operations.
Collaborate with business units and external partners to translate broad transportation needs and policy goals into specific, actionable engineering requirements.
Participate in sprint planning, project scrums, and other agile ceremonies, particularly in technology-focused transportation projects.
