Traffic Engineering in San Antonio & Across Texas
Signal analysis, traffic impact studies, and corridor modeling built on 25+ years of Texas-specific experience — backed by GKW's own in-house data collection.
Traffic Engineering Capabilities
GKW provides comprehensive traffic engineering services for TxDOT, the City of San Antonio, Bexar County, VIA Metropolitan Transit, and private developers — every study and design backed by GKW's own field-verified data.
Traffic Impact Analysis (TIA)
Trip generation, directional distribution, background growth projections, and level-of-service analysis for developments and institutional projects — from single intersections to multi-phase residential buildouts.
Signal Warrant Analysis & Design
Signal warrant studies and traffic signal plans, from initial warrant analysis through final signal design and interconnect.
Speed Zone & Safety Studies
85th-percentile speed studies and crash/safety analysis to support speed zone changes and safety improvements for TxDOT and municipal clients.
Corridor & Signal Timing Modeling
Synchro and HCS-based corridor modeling — from road-diet feasibility to citywide signal retiming programs measured against real performance data.
Traffic Studies & Circulation Analysis
Site circulation, access, and driveway spacing studies to keep developments and campuses operating safely at full buildout.
Agency Coordination
Direct coordination with TxDOT, City of San Antonio, Bexar County, and VIA Metropolitan Transit throughout study, design, and submittal.
TxDOT Precertified in 20+ Categories
GKW is TxDOT-precertified across more than 20 engineering categories, supporting the firm's qualifications for TxDOT and other transportation assignments throughout Texas.
Traffic Engineering Projects
Broadway Corridor — Comprehensive Study & Schematic Design
GKW served as Prime Consultant for Phase 1C of the Broadway Corridor Comprehensive Study, building and running a Synchro traffic model across 19 intersections to demonstrate a road-diet concept could maintain acceptable levels of service while adding bike lanes, wider sidewalks, transit stops, and landscaping.
CMAQ — Citywide Signal Timing Program
GKW developed and implemented optimized Synchro timing plans for the City of San Antonio's CMAQ Citywide Signal Timing Program. On the Babcock Rd. corridor (12 intersections), retiming improved the Network Performance Index 8.04% during the AM peak and cut corridor CO emissions by 8.5 kg/day; the Austin Highway corridor saw up to 13.6% off-peak improvement.
