Focused studies and bid-ready transportation design.
We support city, county, state, and district transportation programs with technical studies and plans, specifications, and estimates (PS&E) for traffic signals and illumination, signing and striping, geometric and channelization improvements, and traffic control.
Where we fit in
We supplement your staff with focused transportation analysis and design, from individual on-call task orders to complete, advertisement-ready PS&E packages.
- Focused traffic operations, parking, safety, access, and circulation studies
- Peer review of applicant traffic and VMT studies during development review
- PS&E packages including plan sheets, special provisions, quantities, and engineer’s estimates prepared to your standards and formats
- Small and midsize capital projects that are difficult to staff internally

Confirm the assignment
Your team establishes the project goals and scope. We confirm our role, the required deliverables, key milestones, and review process before work begins.
Engineer-led analysis and design
Our engineers interpret the applicable requirements, verify project inputs, and establish the analysis or design direction. They then use CPDG’s purpose-built AI platform to develop coordinated transportation analyses, reports, recommendations, and PS&E packages consistent with your standards and formats.
Structured technical and PE review
Automated checks look for missing information, conflicting values, incomplete notes, discrepancies across analyses, reports, and plan sheets, and items that may not align with applicable standards, formats, and project requirements. A licensed California PE then reviews the complete deliverable under responsible charge, resolves any remaining issues, and makes the final engineering decisions.
Delivery and review support
You receive the report, memorandum, concepts, or PS&E package ready for your next decision or internal review, with support through review cycles and revisions.
