Traveler Information

Delaware Department of Transportation’s (DelDOT) Real-Time Traveler Information Program provides current transportation system information to the traveling public through a variety of media including DelDOT’s App, online interactive maps and WTMC 1380 AM. This information complies with Section 511 under Title 23 of the Code of Federal Regulations, which required that states establish a real-time information program for interstates by November 2014 and for routes of significance by November 2016.

Delaware travelers have a lot of information available to them, accessible in a variety of ways. Empowering the public with this information enables them to make informed choices. Thousands of travelers are in touch with DelDOT at any given time; this is a key strategy for making the most out of the transportation system we have.

DelDOT currently provides information on construction activity, incidents, weather and travel time on the public website.

A key achievement that showcases the integrated aspect of the program is the ability for the public to choose which layers of traveler information they want to view.

  • Construction activity reporting is contingent on workers reporting the information to the Transportation Management Center (TMC) technicians.
  • Information about incidents is gained in a variety of ways including roadway detectors and an interface to Police/Fire Computer Aided Dispatch (CAD).
  • Weather and travel time information is collected automatically from devices in the field and is consistently available to the public.
  • Transit system information is provided, including schedule changes and incidents, for bus and rail.

DelDOT is automating the validation process of construction and incident information with a data system named Tracker. Future initiatives include identifying the real time positions of buses as well as obtaining real-time information from system users.

DelDOT App/Social Media

DelDOT’s App is a breakthrough in that it optimizes DelDOT’s access to people. The Mobile App can be used throughout an entire multimodal trip – to aid driving, parking, riding transit and walking. Users can listen to WTMC 1380 AM through the App. DelDOT also has a following on Facebook, Twitter and Instagram.

Transit is an integral component of a well-balanced, multimodal transportation system. To manage both fixed route and paratransit service, the Delaware Transit Corporation (DTC) has implemented the Delaware Advanced Transportation Management System (DATMS). This system provides real-time vehicle locations and schedule adherence status of the transit fleet, along with status messages such as notifications of mechanical issues or breakdowns to help DTC better manage their fleet and improve operational efficiency. The DATMS is now fully installed in the DTC fleet and preparing for system acceptance.

Tmc App

Fully integrating the DATMS with the Integrated Transportation Management System (ITMS) will enhance the transit operations and safety. The expanded system will be capable of providing real-time information to the ITMS in support of traveler information as well as on-board video in support of emergency event management. Fully integrating the DATMS and ITMS will also provide for implementation of a Transit Signal Priority (TSP) system that is centrally controlled by ITMS. A TSP system will further improve DTC operational efficiency by maintaining scheduled route transit times and will make public transit a more attractive alternative to the public.

Transitioning to Operations and Maintenance

Much of the emphasis of the transportation management program since the original Strategic Plan has been on the act of building. Not only has there been a need to build significant infrastructure, but also policies, relationships, awareness and knowledge. Year after year, designs have been documented and construction has occurred. Committees have formed and met faithfully to co-create a truly integrated system. Plans and policies have been developed, published and updated. The result is, some 15 years later, a well-established practice of transportation management in Delaware, supported by a robust and integrated system of telecommunications, devices and information technology, operated and maintained by a diverse team throughout the Delaware Department of Transportation (DelDOT) and beyond, all led out of the Transportation Management Center (TMC) in Smyrna.

Telecommunications and Information Technology

Delaware’s Department of Transportation (DelDOT) and our partners ((Division of Communications (DivComm), with the support of the Federal Highway Administration (FHWA), and the Department of Technology and Information (DTI), have built a robust state-owned telecommunications network.

Telecommunications is behind everything we do (and will do), from moving enormous amounts of real-time data to enabling critical executive management communications during severe incidents. Investment in fiber is a future-proof investment that provides long-term control over cost and outstanding government services. A supporting statewide wireless network interconnects the statewide fiber optic network for the purpose of monitoring and controlling equipment and supporting mobile or voice communication.

In transportation and beyond, people are moving towards using multiple devices. Demand for data will continue to increase. Transportation-related mobile data is a big part of that demand. As a result, the need for telecommunications bandwidth and reliability is growing with no end in sight. We need to build telecommunications corridors that will not have to be rebuilt later. The telecommunications system is the new transportation information superhighway.

Computerized Traffic Signal System

Due to advanced software that relates real-time data to signal timing settings, signals can be much “smarter” today than they used to be, automatically adjusting to changes in traffic demand. Currently, approximately 75% of signals are on system, with all new signals being built on system as standard practice.

Tmc App

The current status of traffic signals is as follows:

  • Approximately 75% of the state’s signals are currently online
  • Conversion of 50 signals per year is a major stated priority, fast-tracking the state to have 100% signals under central computer control
  • Re-evaluation and retiming of the state’s traffic signals is a continuous program, with approximately 20 corridors retimed every year
  • System detectors are being installed statewide to enable traffic responsive operation and real-time data
  • Over a dozen corridors are properly equipped to run in traffic responsive mode, wherein the traffic control software combines traffic monitoring with advanced algorithms to adjust timings in accordance with changes in traffic demand. As more signals get online with more reliable telecommunications, the state can look forward to more corridors with traffic responsive operations.


Many types of devices are used to collect automated data. The main purpose of the monitoring system is incident detection. The system of devices is a mix of fixed and portable sites, including:

  • Video Monitoring System (VMS)
  • Automatic vehicle location (snow plows)
  • Vehicle-mounted live video (Dash Cams)
  • Roadway Weather Information System (RWIS)
  • Signal System Detectors
  • Radar Detection
  • Automatic Traffic Recorders (ATRs)
  • Bluetooth Detection

Portable units enable temporary operations to be set up at work zones, for emergencies and at planned events. Additionally, construction and operations personnel manually track construction and incident information. Some of that information is shared with the public, such as what it is, where it is, the impacts and detours.

Tmc App

Transportation Weather and Flood Monitoring and Warning System

Through the Integrated Transportation Management System (ITMS) system, DelDOT has a functional system of:

  • A variety of locations including roadways, dams and bridges
  • A variety of topology such as inland, coastal and back bay
  • Sensors on and near roadways for real-time surface and subsurface information
  • Hydrology tide gauges measuring water levels
  • Atmospheric sensors for winds and important weather information

Future sites are being prioritized to integrate with the National Highway System (NHS). DelDOT is leading the team to expand and integrate this system with its partners.

Integration of Operations and Planning

Transportation data is used by a variety of people for a variety of reasons in Delaware. Depending on the job responsibility, each type of data is collected in certain formats, at certain locations, at select times and durations. The collection of data has evolved significantly over recent years, with technology used more and manual methods less.

The Integration of Operations and Planning Advisory Committee integrates planning and operations functions to maximize data sharing and track system performance. Together, planners and operators are:

  • Defining the types of transportation data needed
  • Specifying equipment to collect transportation data
  • Locating the equipment throughout the state
  • Integrating the data in a database
  • Sharing the data through a common interface

Congestion and Mobility Management

Emerging data sources are enabling Delaware’s transportation planning and operations team to monitor and manage mobility better than ever before. Our team is using data to:

  • Monitor with agreed-upon measures of effectiveness
  • Evaluate reliability statewide
  • Identify needs and options for improvements
  • Assess return on investment
  • Prioritize funding
  • Assess performance with before-and-after studies

Incident and Event Management

Tmc App

Planned and unplanned incidents occur daily and many individual incidents span multiple days or even months. Intensive teamwork in the development of plans and policies, and in the practice of those policies, is required to perform at top efficiency. Hundreds of key stakeholders interact daily within DelDOT, within Delaware, within the region.

Transportation Management Team

The concept of the Transportation Management Team (TMT) was introduced in the 1997 Strategic Plan. The Strategic Plan recognized that effective transportation management requires the cooperation and coordination of people and agencies, and recommended that the Delaware Department of Transportation (DelDOT) implement an incident management team composed of police, fire and rescue, natural resources and transportation agencies. The TMT was envisioned as a dynamic group that works together, not only for planning purposes but also for field operations, to support the management of incidents and events that impact the transportation system.

The goal of the TMT program is to improve response to transportation-related incidents by improving interagency training, communications, operations and resources. From the initial meetings in 2005 through today, the TMTs have worked together to improve transportation incident and event management throughout Delaware. Some of the TMT achievements include:

  • Detour routes for major roadways statewide
  • All-hazards evacuation plans, including evacuation route identification statewide
  • Communications working group
  • Multi-agency incident management training and exercises
  • Special event coordination
  • Safe, quick clearance legislation
  • Good forum to disseminate information and obtain feedback on major capital projects

Emergency Response Units & the Motorist Assistance Patrol Program

Tmc App

The Motorist Assistance Patrol (MAP) patrols rush hour and construction-related congestion areas in specially equipped vehicles. They offer motorist assistance, assist at incident scenes and communicate problems to the Transportation Management Center (TMC). On average, MAP vehicles make 30 assists per week.

Emergency response units (ERUs) are a team of trained transportation specialists, ready to be deployed at short notice to provide specific support or direct services to motorists that need assistance during events that affect the transportation system. ERU patrollers patrol the transportation system in assigned areas and report any and all incidents or disruptions to traffic, including traffic delays and roadway condition information to the TMC. Duties of the patroller are varied and may include, but are not limited to, the following:

  • Setting up traffic control and/or detour routes at scenes of major incidents
  • Relocating stalled vehicles from potentially hazardous situations
  • Providing road and travel information
  • Reporting or removing debris from the roadway
  • Performing minor mechanical repairs to disabled vehicles as abilities allow
  • Providing coolant or other engine fluids
  • Jump starting vehicles
  • Changing flat tires
  • Assisting motorists out of snow banks
  • Reporting of weather conditions
  • Reporting of malfunctioned/dark traffic signals and downed traffic control devices
  • Deploying and activating portable message boards

Transportation Homeland Security

Security threats can trump all other business in the transportation program. In a category all its own, DelDOT managers work with local, state and national partners to build, maintain and operate a resilient transportation system with redundancy and flexibility.
