Traffic & Transportation Engineering in Phoenix
Traffic studies that pass review, signals that actually flow, and street designs the whole Valley can live with — data first, drama never.
Every Question a Street Can Ask
From a single driveway's impact to a whole corridor's redesign — studied, modeled, and defended.
Congestion Is a Design Problem
Traffic doesn't just happen — it's the output of a thousand design decisions, and most of them can be improved. We count what's really there, model what's really coming, and recommend what the data supports. Then we stand up at the hearing and defend it, because a study that folds under questioning wasn't engineering.
- ✓Real counts at real peak hours — never borrowed data
- ✓Models calibrated until they match the street
- ✓Recommendations ranked by measured benefit
- ✓Engineers who present and defend at hearings
The Cheapest Capacity Money Can Buy
Before anyone widens a road, retime the signals. A corridor retiming costs a rounding error of construction and routinely returns double-digit delay reductions — ours average thirty-one percent. We measure before, tune the plans, and measure after, so the improvement is a number, not a feeling.
- ✓Before-and-after studies on every retiming
- ✓Coordination plans tuned to real platoons
- ✓Peak, off-peak, and weekend plans that fit
- ✓Documentation your council can celebrate
Why Our Studies Hold Up
Data Beats Opinion
Every recommendation traces to a count, a crash record, or a calibrated model. Opinions don't survive hearings; data does.
Reviewers Are the First Audience
Studies formatted to each jurisdiction's checklist — ninety-seven percent accepted on first review.
Streets Are for People
Throughput matters, but so does the kid on the bike. We design for the street's whole population.
Every Study Includes
Sealed Engineering Report
PE-stamped, jurisdiction-formatted, and written to be read — not just filed.
Count Data & Models
Raw counts and model files delivered with the report — your data, fully auditable.
Hearing-Ready Exhibits
Clear graphics that explain the traffic story to people who don't read traffic studies.
Reviewer Response Support
Comment responses drafted fast — the study isn't done until it's accepted.
Presentation at Hearings
An engineer at the podium when the project needs one — steady, clear, prepared.
Post-Approval Follow-Through
Conditions tracked and closeout documentation handled through buildout.
From Hearings Won and Corridors Fixed
Our rezoning hinged on the traffic study, and the neighbors came ready to fight. Corridor's engineer presented the data so clearly the council's questions ran out before the objections did. Approved, 6-1.
They retimed eleven signals on our worst arterial and morning delay dropped by a third — measured, not estimated. Residents actually called to say thank you. That has never happened.
The roundabout they designed replaced our most-crashed intersection. Two years in: injury crashes down to zero, and it moves more cars than the signal ever did. The data made the case; the design delivered it.
Asked Before the Count
Do I actually need a traffic impact study?
If the jurisdiction says so, yes — and the threshold varies by city and project size. Send us the project description and we'll tell you what's required, what it costs, and how long it takes, for free.
How long does a traffic study take?
Simple studies run three to four weeks including counts; complex rezonings longer. Counts must happen when school's in session and traffic is typical, so calendar timing matters — ask early.
What does a study cost?
Small site studies start in the low thousands; corridor and rezoning studies scale with intersections analyzed. Fees are fixed and itemized — no meter running.
The city rejected our last consultant's study. Can you fix it?
Usually — most rejections trace to scope misses or uncalibrated models. We review what exists, meet with staff to reset expectations, and rebuild only what's actually broken.
Will you present at our public hearing?
Yes, and we're good at it. Traffic is often the loudest objection in the room — a calm engineer with clear exhibits changes the temperature of the whole evening.
Do you work for cities as well as developers?
Both, deliberately — designing for cities keeps our developer studies honest, and knowing developer realities keeps our city work practical. The street doesn't care who's paying.
The Count Window Is the Critical Path.
Traffic counts need typical conditions — miss the window and the study waits a season. Scope it now and the calendar works for you.
