About Traffic Associates

Traffic Associates is a Los Angeles-based civil and traffic engineering firm focused on practical, agency-ready support for development, construction, and public works projects. Our work helps clients respond to city comments, understand technical requirements, and prepare the reports and plans needed for review.

We support projects through services such as VMT screening, trip generation analysis, traffic impact analysis, queuing and circulation studies, construction traffic management plans, traffic control plans, signing and striping plans, ADA access review, and civil/site design support.

Our approach is straightforward: identify what the reviewing agency is asking for, define a practical scope, prepare a clear deliverable, and support the project team through comments and revisions.

What We Help With

  • City comments
  • Permit requirements
  • Transportation reports
  • Construction traffic plans
  • Site access and circulation
  • Agency response support

Built for Practical Project Support

Traffic Associates was built to provide focused civil and traffic engineering support without unnecessary layers or overcomplicated processes. Many clients come to us when they have a project address, a plan set, a city comment, or a permit requirement and need to understand the next step.

Rather than treating each task as a generic study or plan, we focus on the actual review need: what the agency is asking for, what documentation is required, what assumptions need to be explained, and how the deliverable can support the approval process.

“We are not trying to make engineering more complicated. We help project teams understand what is needed, prepare the right documentation, and move forward with confidence.”

What Makes Us Different

Traffic Associates combines technical engineering support with a practical understanding of how projects move through local review.

Approval-Focused Engineering

We prepare reports and plans with agency review, city comments, and submittal requirements in mind.

Civil + Traffic Perspective

We look at access, circulation, frontage conditions, construction staging, ADA, and transportation requirements together instead of treating them as disconnected issues.

Direct, Practical Communication

Clients receive clear guidance on likely deliverables, scope, schedule, and next steps.

Local Southern California Experience

We support projects throughout Los Angeles County and surrounding counties and understand the coordination needs of Southern California development and construction review.

How We Support Project Teams

Whether a project is in early planning, entitlement review, plan check, or construction, Traffic Associates helps translate requirements into clear engineering deliverables.

We review the project address, plan set, agency comments, or permit requirements.

2

Identify the Need

We help determine whether the project needs a report, plan, technical memo, comment response, or design support.

3

Prepare the Deliverable

We prepare the civil or traffic engineering documentation needed for submittal.

4

Support Review

We help respond to comments, revise deliverables, and coordinate next steps as the project moves through review.

Need help identifying the right scope?
