Traffic Engineering Branch

 Traffic Engineering Branch


SDDCTEA functions as the DoD proponent for overall DoD traffic engineering coordination, technical assistance, and development of installation traffic engineering studies [AR55-80].


The mission of the DoD Traffic Engineering (TE) Program is to improve safety and efficiency on DoD installation road networks and entry control facilities or access control points. To accomplish the mission, the TE Program team engages in a variety of activities to include the following:

  • Publish guidance documents (pamphlets & bulletins)
  • Provide technical assistance
  • Conduct traffic engineering studies
  • Provide Training
  • Develop and distribute engineering software ..(ACP/ECF SMART Decision Evaluator and Better Military Traffic Engineering)
  • Conduct research supporting safety and efficiency


Better Military Traffic Engineering (BMTE): The purpose of this software is to provide installation engineers with proper traffic engineering procedures, references and common traffic, security and safety issues through tutorials. The BMTE is also equipped with multiple software tools to aid in common traffic engineering calculations used during the planning, design and operational phases.

Security Manpower Automation Roads & Lanes Traffic & Safety (SMART):  We have developed a new version of our SMART Decision Evaluator that is user friendly and is no longer web-based. The new version uses Microsoft Excel and can be downloaded by clicking on the SMART Evaluator link below. Be sure to read the ReadMe Tab prior to using and for any question you can contact the Traffic Engineering Team at

The ACP/ECF SMART Decision Evaluator still provides perspective on issues associated with ACP processing. When combined with practical knowledge, SMART helps make decisions with full awareness of the ramifications.

The objective of ECFs/ACPs is to secure the installation from unauthorized access and intercept contraband (weapons, explosives, drugs, classified material, etc.) while maximizing vehicular traffic flow by ensuring the proper level of access control and safety for all DoD personnel, visitors, and commercial traffic to an installation.  The overarching priorities are security, safety, capacity, and sustainability.

Traffic Engineering and Safety (TES) Seminars: Since 2006 the Traffic Engineering Branch has hosted TES Seminars to assist installation safety, law enforcement, engineering, and command personnel by providing guidance on traffic engineering and safety considerations along roadways, intersections, and at entry control facilities (ECF) / access control points (ACP). Information is also provided on planning, designing, and operations of ECF/ACP considering security, safety, and traffic requirements.

The topics covered in TES Seminars are:

  • ECF background and facilities                                                     
  • Geometric Design
  • Signs, Markings, and Retroreflectivity                                     
  • Active Vehicle Barriers
  • Signs and Markings for ECF                                                         
  • Traffic Engineering Studies
  • Access Management and Parking
  • Speed Management (i.e., Speed Limits and Traffic Calming)                           
  • Pedestrian Accessibility for Persons with Disabilities        
  • Standards and Guidelines
  • Roadside and Pedestrian Safety                                               
  • Roundabouts
  • Traffic Signals and Intelligent Transportation Systems     
  • Introduction to the Manual on Uniform Traffic Control Devices (MUTCD)
  • Hands-on exercise: Intersection Traffic Safety Assessment and ECF Design
