Designing networks that move people efficiently, not just vehicles.
Zifel Engineering delivers traffic signal design, signing & pavement marking plans, and transportation planning built around one principle: every second of unnecessary delay is wasted fuel and wasted emissions.
Two disciplines, one connected practice
Design and planning inform each other. A signal plan is only as good as the demand forecast behind it; a corridor plan only matters if it's buildable. We run both under one roof.
Traffic Engineering Design
Construction-ready plans that get permitted the first time and operate the way they were intended to.
- Traffic signal design & timing plans
- Signing & pavement marking plans
- Maintenance of Traffic (MOT) plans
- Intersection & geometric design
- Roundabout & channelization design
- Signal interconnect & ITS design
Traffic Engineering Planning
The analysis that tells you what to build, where, and why, before money is spent on design.
- Traffic impact studies
- Corridor & network planning
- Signal warrant & intersection control analysis
- Capacity & level-of-service analysis
- Multimodal & complete-streets planning
- Site access & circulation planning
Efficiency is the sustainable choice.
Every unnecessary stop, every poorly timed phase, and every over-built intersection has a cost measured in idling fuel and tailpipe emissions long before it shows up on a balance sheet. We treat that as an engineering problem, not a marketing one.
Our designs and plans are built to move people, goods, and vehicles through a network with the least possible friction, drawing on standard practice from MUTCD, AASHTO, and state-level design guidance, while looking for the lower-impact solution at every decision point: a re-timed signal before a new lane, a roundabout before a four-way signal, a shared-use path before a parking expansion.
Built to be the firm we'd want to hire.
Zifel Engineering was founded on a simple belief: transportation infrastructure should be designed by people who understand both the regulations that govern it and the communities that live with it.
We work directly with municipalities, developers, and agencies, translating traffic data and design standards into plans that get approved, get built, and actually perform once they're in the ground.
Standards-driven
Every plan is grounded in MUTCD, AASHTO, and the governing state design manual.
Built for approval
We design for the reviewer and the contractor as much as for the driver.
Efficiency-first
The lowest-impact solution that meets the need is always our starting point.
