About the Role

Role Overview

Lead traffic engineering and transport planning tasks for major infrastructure projects, with a strong focus on Dubai RTA‑compliant Temporary Traffic Management (TTM), diversions, and traffic staging, alongside permanent traffic impact assessments (TIA), junction analysis, access planning, and traffic signage/road markings coordination. The role will support design development, authority approvals, and construction‑phase traffic management in close coordination with highways, utilities, and construction teams.

Key Responsibilities
  • Lead delivery of Traffic Impact Assessments (TIA) and supporting technical studies for road and transport infrastructure projects (greenfield and brownfield).
  • Develop and manage TTM / work zone traffic management deliverables, including:
    • Diversion plans, detour layouts, staging/phasing plans, lane closure schemes, and construction access/egress arrangements
    • Temporary signage and road marking plans, traffic control devices, safety barriers, and pedestrian management (where applicable)
    • Methodology narratives, risk assessments, and sequencing aligned with construction methodology and site constraints
  • Manage Dubai RTA coordination and approvals for TTM/diversions, including preparation of submission packages, responding to RTA comments, and aligning with RTA requirements, standards, and typical details.
  • Perform junction and corridor analysis (existing and forecast), including capacity, LOS, queues, delays, and operational performance under base and construction‑stage scenarios.
  • Undertake traffic surveys scoping and interpretation: turning counts, mid‑block counts, travel time runs, parking demand, pedestrian counts, heavy vehicle counts; develop calibrated base models where required.
  • Develop traffic modelling and scenario testing for:
    • Permanent scheme impacts (new intersections, access points, ramp terminals, weaving sections)
    • Construction‑stage impacts (temporary lane drops, detours, signal timing changes, partial closures)
    • Mitigation measures (signal optimization, geometry refinements, temporary signal plans, reversible lanes where permissible)
  • Prepare signage and road marking design inputs and reviews, including:
    • Permanent guide signs, regulatory/warning signs, VMS interface needs (if applicable), and marking strategy
    • Temporary signage for work zones/diversions in accordance with RTA expectations and safety practice
  • Coordinate with multidisciplinary teams: highways geometric design, utilities, structures, construction planning, safety, and stakeholder interfaces (developers, local authorities, police/ambulance access requirements where applicable).
  • Provide construction support: review contractor TTM submissions, respond to RFIs, participate in site coordination meetings, and support implementation readiness checks.
  • Prepare deliverables and governance documentation: design reports, TIA reports, concept/IFC drawings, phasing narratives, traffic management plans, and authority submission trackers.
What do we need from you

Qualifications & Experience

  • Bachelor’s degree in Civil Engineering / Transportation Engineering (Master’s preferred).
  • 12–15 years of experience in traffic engineering and transport planning with substantial exposure to:
    • Dubai RTA processes for TTM/diversions and authority submissions (mandatory)
    • Traffic impact assessments for major developments and infrastructure corridors
    • Work zone traffic management, staging, and safe diversion planning on live roads
  • Strong technical understanding of:
    • Signalized/unsignalized intersection operations, corridor performance, access management
    • Temporary traffic controls, pedestrian management, safety barriers, and staging constraints
    • Traffic signage and pavement markings principles (temporary and permanent)
  • Experience producing coordinated deliverables suitable for authority review and construction implementation, with strong QA/QC discipline.
  • Preferable: exposure to Middle East standards and stakeholder management for constrained urban construction environments.
What's in it for you?

Software

  • Traffic analysis / TIA: any combination of PTV VISSIM, Aimsun, SIDRA Intersection, Synchro/Sim Traffic, HCS (Highway Capacity Software).
  • Junction / geometry checks:
    AutoTURN / Vehicle Tracking, basic swept path capability, parking and access evaluation tools.
  • CAD / drawings:
    AutoCAD (mandatory);
    Civil 3D preferred for geometry coordination;
    Bluebeam for markups.
  • GIS / data: QGIS / ArcGIS preferred; strong Excel capability for survey reduction and reporting.
  • Document management / collaboration: ACC or equivalent CDE platforms (preferred).
