Over the last three years, ATCS has played a pivotal role in supporting VDOT’s efforts to enhance traffic management and safety in Virginia’s Southwest Region. As the prime consultant on the Southwest Region Traffic Engineering On-Call contract, ATCS delivered a wide range of traffic engineering services, addressing complex challenges and driving substantial improvements across the region.
Bristol District
Systemic Unsignalized Intersection Traffic & Safety Design:
ATCS screened, assessed, and provided design drawings and estimates for signing, marking, and other low-cost systemic safety improvements at critical unsignalized intersections identified as having high Potential for Safety Improvement or Targeted Safety Needs. We completed improvements at 66 intersections, under budget and within six months, and provided additional support to advance the improvement recommendations to advertisement.
Bristol District Curve Warning:
ATCS evaluated 314 locations across the Bristol District, conducting sign inventories and curve speed analyses using ball bank indicators to identify which locations required new or updated curve warning signage, including deficient speed panels. All field data was assessed for MUTCD compliance for chevron sign installations. The final report included a transportation management plan, erosion and sediment control notes, a summary of quantities, and relevant maps and recommendations for sign installations. All work was completed on time and under the original task order budget.
Lynchburg District
Route 29 & Route 685 Signal Design:
ATCS developed comprehensive traffic signal plans, pavement marking plans, and intersection lighting plans and performed traffic analyses to determine optimal signal phase splits and appropriate left turn phasing. The intersection was also reviewed for potential pedestrian accommodations.
Timberlake Road (US 460 Business) Signal Optimization:
ATCS optimized signal timing plans for the AM, PM, and Midday periods for 17 intersections along Timberlake Road (US 460 Business). We developed revised Synchro files, monitored operations post-implementation, and conducted a follow-up assessment after 30 days to verify the validity of the implemented timings.
Salem District
MS365 Work Order Tracker Workbook Migration:
ATCS provided technical support and training for the development and use of the MS365 work order tracking process using SharePoint and Power Platform applications, enhancing project management and coordination.
Ancillary Structure GuideSIGN Design:
ATCS delivered overhead sign design plans for 58 sign panels. We ensured efficient design practices and close coordination with VDOT, including multiple messaging options to ensure clarity and compliance. All designs were developed to match existing dimensions to prevent any additional or changed loading on existing structures.
Impact
ATCS’ partnership with VDOT on the Southwest Region Traffic Engineering On-Call contract has directly enhanced road safety and efficiency, benefiting Virginia’s communities by making travel safer and improving daily commutes. These improvements align with VDOT’s mission to enhance the transportation infrastructure and support economic growth. This successful collaboration promotes sustainable transportation solutions that contribute to public safety and regional development by meeting immediate needs and laying the groundwork for future advancements.
