Municipal Traffic Engineering & Planning
Cities and public agencies face increasing demands on their transportation networks, from development review and multimodal planning to lighting standards and day-to-day operational needs. TJW Engineering supports municipalities by providing specialized technical expertise, staff extension services, and data-driven analysis that help agencies address these challenges in compliance with FHWA, AASHTO, MUTCD, and local standards.
TJW’s team includes registered Civil Engineers, experienced Traffic Engineers, Professional Transportation Planners (PTP), certified Lighting Designers, and IMSA-certified professionals in traffic signal operations and work zone safety. This multidisciplinary capability allows TJW to support a wide range of municipal needs with technical depth, responsiveness, and practical engineering solutions.
Technical Support & Staff Extension Services
TJW partners with public agencies to supplement staff, address workload fluctuations, and provide expert support for routine and complex traffic engineering tasks, including:
- Day-to-day traffic engineering assistance
- Plan review, technical memos, and design oversight
- Development review and permit support
- Coordination with developers, consultants, and stakeholder groups
Safety Studies, Collision Analysis & Operational Review
Agencies are responsible for monitoring roadway performance and addressing operational and collision-related concerns. TJW conducts detailed studies to identify trends, evaluate conditions, and develop engineering-based recommendations that support data-driven planning and compliance with state requirements through:
- Safety and collision trend analysis
- Roadway operational and capacity evaluations
- Speed surveys and Engineering & Traffic Surveys (E&TS)
- Before-and-after studies to measure improvement effectiveness
Traffic Control Warrants & Multimodal Planning
TJW assists agencies in making informed decisions about traffic control and multimodal improvements. Findings are documented in clear, defensible reports that support grant applications and agency decision-making, including:
- Traffic signal, stop sign, PHB, and flashing beacon warrant analysis
- Safe Routes to School evaluations
- Walkability and pedestrian/bicycle safety assessments
- Active transportation planning and project identification
Traffic Impact Studies, VMT Analysis & Peer Review
TJW delivers clear, actionable findings that align with agency procedures, adopted policies, and regulatory expectations. Municipalities rely on TJW to evaluate development proposals and ensure conformance with CEQA, SB 743, and local policies through:
- Traffic impact studies and operations analysis
- VMT screening, modeling, and analytical review
- Peer review of consultant-prepared TIA/TIS reports
- Scenario evaluation using industry-standard modeling tools (Synchro, SimTraffic, PTV Vistro, Vissim, TransCAD)
Lighting Review & Photometric Analysis
TJW provides municipal support for lighting design review, safety analysis, and compliance with agency lighting practices. TJW’s expertise includes review of LS/LC-caliber lighting design and analysis, including:
- Photometric study review and lighting standards evaluation
- Intersection, corridor, and site lighting assessments
- Lighting recommendations that consider visibility, uniformity, and agency criteria
Geometric Review, Alignment Studies & Storage Evaluations
Sound geometric design is essential for effective roadway performance. TJW assists agencies with:
- Alignment studies and conceptual layouts
- Turn pocket and storage length evaluations
- Geometric review for new development or capital projects
Traffic Management for Events & Construction
TJW prepares clear, compliant plans that help agencies manage travel during events and construction, including:
- Traffic management plans for concerts, festivals, and special events
- Detour and routing plans for short-term and long-term construction
- Review of traffic control plans to ensure MUTCD and agency compliance
