Traffic Data Collection
Manual and automated field data — all collected in-house — supporting planning, design, and TxDOT submittals across Texas.
Field Data Collection Capabilities
GKW operates its own field crews and equipment, providing traffic data collection as a standalone service or as part of a larger planning, traffic engineering, or roadway design assignment. Every count, study, and inventory is collected in-house to support municipal, TxDOT, consultant, and private-sector projects across Texas, including construction engineering and inspection (CE&I) assignments that depend on accurate field data.
Manual & Automated Traffic Counts
Turning movement counts (12-hour at major intersections, 5-hour at minor), continuous 7-day and 24-hour tube counts, and vehicle classification counts.
Speed & Travel Time Studies
85th-percentile speed checks using radar guns and GPS-integrated tube counters, plus before-and-after travel time runs using INRIX IQ Roadway Analytics.
Sign & Roadway Inventory
Sign reflectivity testing (large and small signs), signing inventory, roadway inventory, and curve analysis to support asset management and safety programs.
Intersection & Signal Equipment Inventory
Full intersection inventories — cabinet make/model/serial number, controller type and firmware, pole and mast-arm type, signal head count, detection and communications equipment, and ADA ramp compliance.
Origin-Destination Data
Origin-destination studies supporting corridor and transportation planning work.
Proprietary Field Software
GKW uses proprietary in-house field software that captures data efficiently, helps standardize collected information, automatically populates applicable TxDOT speed-check forms, and supports fast, accurate deliverable preparation — without relying on manual, duplicate data entry.
All Data Collected In-House
Every count, study, and inventory on this page is collected and managed by GKW's own field teams — not subcontracted. That means GKW controls scheduling directly, applies consistent field procedures from project to project, and gets faster internal access to the collected data — supporting stronger quality assurance and faster preparation of project-ready and TxDOT-ready deliverables.
Traffic Data Collection Projects
CMAQ — Corridor Data Collection & Intersection Inventory
Every CMAQ signal timing plan GKW built started with field-verified data: continuous 7-day and 24-hour tube counts, AM/PM/off-peak turning movement counts, before-and-after travel time data from INRIX IQ Roadway Analytics, and a full intersection inventory covering cabinets, controllers, poles, signal heads, detection, and ADA ramp compliance.
TxDOT El Paso District — Speed Safety Study & Field Data Collection
GKW performed 85th-percentile speed checks across multiple West Texas corridors — El Paso, Alpine, Jeff Davis, Marfa, Dell City, and Big Bend — for TxDOT under prime consultant Atkins North America, using radar guns and GPS-integrated tube counters, plus travel runs with video and sign inventories.
