Engineering Solutions for Public Infrastructure
From traffic impact studies to full corridor studies to traffic signal design, CANDIE delivers the technical depth and government requirement compliance experience that municipalities, counties and state agencies depend on.
Traffic Studies
Data-driven analysis that informs sound infrastructure decisions.
Our traffic engineering team conducts comprehensive traffic studies that meet city, county state and federal standards, giving agencies the evidence they need to plan, fund, and mitigate impacts to infrastructure investments.
Traffic Impact Assessments
Evaluate the effects of new development or roadway changes on the surrounding network, including level-of-service analysis and mitigation recommendations.
Volume & Speed Studies
Automated and manual traffic counts, turning movement counts, and speed surveys to establish baseline conditions and support design decisions.
Safety Analyses
Crash data review, conflict point identification, and countermeasure recommendations aligned with FHWA's Safe System approach.
Signal Warrant Studies
MUTCD-compliant warrant analyses to determine whether traffic control signals are justified at a given location.
Pedestrian & Bicycle Studies
Gap acceptance studies, crossing demand analysis, and multimodal level-of-service assessments for active transportation planning.
Traffic Signal Design
Precision signal engineering built for long-term municipal operability.
We design traffic signal systems that optimize intersection performance, reduce delay, and comply with MUTCD and state standards — from single intersections to coordinated corridor systems.
Intersection Signal Design
Complete signal design packages including plans, specifications, cost estimates, phasing, timing plans, detection layout, and controller specifications for new and modified intersections.
Adaptive Signal Control
Design and specification of adaptive signal control technology (ASCT) systems that respond to real-time traffic conditions across coordinated corridors.
Signal Timing Optimization
Retiming programs using SYNCHRO, SimTraffic, and field observation to reduce delay and improve progression along arterial corridors.
Pedestrian Signal Upgrades
Accessible pedestrian signal (APS) design and ADA-compliant pushbutton placement to meet federal accessibility requirements.
Signal System Modernization
Assessment and replacement of aging signal infrastructure, including controller upgrades, fiber interconnect design, and ATMS integration.
Transportation Planning
Long-range plans that translate mobility data into actionable policy.
CANDIE helps municipalities, regional agencies & state DOT's plan the next generation of transportation infrastructure — integrating roadway, traffic signal systems and ITS networks into coherent, fundable capital programs.
Long-Range Transportation Plans
20-year transportation plans that satisfy regional, federal and state planning requirements while reflecting local community priorities and growth projections.
Corridor Studies
Detailed analysis of specific roadway corridors to identify deficiencies, evaluate improvement alternatives, and develop preferred improvement programs.
Autonomous Vehicle Management
Strategies to modify transportation infrastructure (roads & parking) to best adapt to connected autonomous electric vehicles (RoboTaxis) deployment on city streets, such as more pick-up & drop-off and less parking.
Capital Improvement Programming
Prioritization frameworks and funding strategies that align transportation needs with available federal, state, and local resources.
Environmental Documentation
NEPA categorical exclusions, environmental assessments, and coordination with resource agencies for federally funded projects.
Our Engagement Process
Scoping & Discovery
We begin every engagement with a structured scoping session to define project objectives, deliverables, schedule, cost, exclusions and success criteria — before a single hour is billed.
Data Collection & Analysis
Field data collection, traffic modeling, and technical analysis conducted by licensed engineers with direct experience on public-sector projects.
Deliverable Review
Draft deliverables are reviewed internally before client submission. We do not deliver first drafts — we deliver near-final work.
Agency Coordination
We manage coordination with state DOTs, FHWA, and other review agencies on your behalf — reducing the administrative burden on municipal staff.
