Engineering the Roads That Move Communities
CANDIE (Critical American National Defense Infrastructure Engineering) delivers top quality transportation engineering — traffic studies, interchange type selection, intersection & traffic signal design, and traffic planning solutions built for the infrastructure challenges that matter most.
Proven Track Record
Engineering Solutions for Public Infrastructure
Traffic Studies
Comprehensive traffic impact assessments, volume counts, trip & parking generation, traffic operations analysis, mitigation measure development and safety studies that meet city, county, state and federal standards. Our data-driven approach gives agencies the evidence they need to make sound infrastructure decisions.
Learn More →Traffic Signal Design
From signal warrant analyses to full intersection traffic signal control plans, we design traffic signal systems that optimize flow, reduce delay, improve safety, and meet MUTCD standards. Our designs are built for long-term operability and municipal maintenance.
Learn More →Transportation Planning
Long-range transportation plans, corridor studies, development area transportation plans and multimodal network analysis for municipalities planning the next decade of infrastructure. We translate complex mobility data into actionable policy and capital programs.

Government-Grade Expertise
Our engineers are trained in federal, state, county & city compliance requirements. We understand the procurement, reporting, and accountability standards that public-sector clients demand. Can present analysis results and design solutions to decision makers in a clear way.
Proven Methodology
Every engagement follows a rigorous, documented process — from scoping through final deliveries. Our methodology is built on 27 years of public infrastructure and land development work.
On-Time, On-Budget Delivery
We have an approximately 90% on-time delivery record across 100+ projects. Client timelines and budget cycles are not suggestions — they are commitments we take seriously.
Infrastructure That Serves Communities
State Route 238 Widening & Improvements
Traffic impact analysis of proposed, and likely adjacent development, intersection type and control alternatives (roundabouts or traffic signs), and intersection & traffic signal preliminary design for a 2-mile arterial expansion from two to four lanes with access control median and turn lanes.
I-15 Farmington to Salt Lake City EIS
Lead the traffic simulation modeling efforts for the I-15 Davis EIS. Simulation included a 17 mile VISSIM freeway model from Salt Lake City to Farmington, Utah to evaluate widening. It also included nine interchange VISSIM models to evaluate different interchange configuration for optimal type, lane requirements and storage lengths.
20th Street HOV/BAT Lanes
Led the traffic operations microscopic simulation analysis and the writing of the Traffic Analysis Report for the addition of a westbound High Occupancy Vehicle (HOV), and Business Access and Transit (BAT) lane on westbound 20th Street. The project provided an uncongested westbound lane so transit vehicles and high occupancy vehicles can bypass the long westbound queue during the AM peak period.
