Weris has been at the forefront of design, implementation, and operation of state-of-the-art ITS technologies. For example, Weris was appointed as the “ITS Technology Manager” in support of a state DOT’s traffic management center in a large congested metropolitan area. Our capabilities in ITS are represented by our in-depth experience in ITS research, ITS implementation, and Advanced Traffic Management Systems. 

ITS Research

Weris also has been actively engaged in ITS research with a focus on real-time traffic data capturing and management, active traffic management, travel time reliability, traffic incident management, As an example, we have been actively participating the following projects under the 2nd Strategic Highway Research Program (SHRP 2):

  • Archive for Reliability and Related Data
  • Post-Course Assessment and Reporting Tool for Trainers and TIM Responders Using the SHRP 2 Interdisciplinary Traffic Incident Management Curriculum
  • Forecasting & Delivery of Travel Time Reliability Information
  • Development of Improved Economic Analysis Tools for Travel Time Reliability Valuation
ITS Implementation and Operations

Weris not only has thorough knowledge but also hands-on experience in planning, implementation, and operations of almost all state-of-the-art ITS technologies, including:

  • Dynamic message signs
  • Ramp metering
  • Lane control
  • Active traffic management
  • Real-time traffic data delivery 
  • Real-time travel time posting
  • High-occupancy and tolling operations
  • Detector data capturing and archiving
  • Integrated corridor management
  • Travel time reliability analysis

We have worked with a wide range of ITS professionals and organizations. In particular, we have thorough knowledge of the ITS audiences related to traffic management centers. Examples of these audiences include: 

  • State departments of transportation traffic management centers
  • County and city traffic management centers
  • Traffic Operations Center (TOC) managers, supervisors, and operators
  • Road safety service patrols
  • State police, 911, fire rescue organizations 
  • Private toll road investors and operators.
  • Regional traffic operations consortiums
Advanced Traffic Management System (ATMS)

Weris staff has built a broad knowledge base on state DOT’s Advanced Traffic Management System programs. One of Weris’ unique strengths is its proven information system planning, design, development support, and implementation capability in ATMS. We have particularly strong capabilities and experience in the following ATMS areas: 

  • Project Management
  • Requirements Definitions and Management
  • Use Case Design and Analysis 
  • System Architecture Analysis
  • Database Design and Implementation
  • Field Testing and User Acceptance Testing
  • Troubleshooting
  • Operations and Maintenance

We use web-based tools to manage requirements definitions and user acceptance testing, which provides customers with whatever level of visibility they desire into the process. Managing requirements is a critical task throughout the entire software development lifecycle process. Our approach is to use off-the-shelf software tools to manage requirements so that we can systematically track any changes to a requirement and maintain its traceability to final testing and deliverables.

Client Success Stories
  • Weris led the successful roll-out of travel time posting on Dynamic Message Signs (DMS) on I-66 in Northern Virginia. After its successful deployment, our team continued to look for ways to leverage the Travel Time component to further benefit regional motorists and related public service agencies. The Weris team conducted a roadside survey along I-66 between Washington, DC, and Gainesville where dynamic message signs were available. The team took pictures of each sign and noted its size and location as well as its nearest exits. We then made recommendations on how to make better use of the strategically placed message signs for travel time dissemination. These recommendations were intended to provide motorists with a broader and continuous coverage of travel times, and allow them to make more informed and timely decisions.
  • Weris successfully implemented several initiatives to improve incident and congestion management and handling, such as an “Instant Towing Dispatching” campaign to reduce incident-related congestion time based on an analysis of historical performance, equipping safety service patrol trucks with mobile cameras to better capture and disseminate better road conditions and incident information, and installing portable signs on safety service patrol trucks to redirect traffic and improve incident handling.
  • Weris provided technical leadership in the design, equipping, and acceptance of a new signal control room at VDOT's Northern Virginia traffic management center (TMC). At the TMC, the signal control room is critical to the agency’s traffic operations. The traffic signal system controls and optimizes signals on state roads. All signals within this network are monitored to ensure that the signal timing is optimal to provide safe and smooth traffic flow.
