Editor's Notes
- Traffic congestion is a significant problem in the urban areas. results in unreliable travel times in the system. Public agencies typically use a diversified approach. On one hand, they try and add lanes On the other, they try to operate the system more efficiently.
- Advanced Traffic Management System involves the use of ITS devices to collect data, view current traffic conditions. If an incident is detected, use dissemination devices like Dynamic Message Signs to make motorists aware of the traffic conditions. ATMS helps effectively respond to incidents. It can also help better manage recurring congestion by proactively disseminating information about it.
- FDOT started deploying ATMS systems in early 2000. Initially, most of our regions purchased vendor products. To better coordinate among Districts and save cost on TMC software development and maintenance, in 2002, FDOT conducted a study and decided to develop a statewide software system. FDOT partnered with Texas DOT on software development. FDOT used their software, added additional features and customized the software to FDOT’s needs. Currently, SunGuide is jointly owned by Texas DOT and Florida DOT. FDOT had the first fully functional software available in 2005 and have been using the software in operational environment for the past 6 to 7 years. All regional TMCs in Florida use SunGuide to manage the roadways.SunGuide software was developed using the best practices prescribed by the software industry including systems engineering. The software uses modular architecture that allows the software to grow as the user’s needs change or as technology evolves.
- Moving forward, instead of talking about what SunGuide does, we will talk about the key activities that Traffic Management Centers perform and we will discuss how the software can help with each one of these activities.
- It was important for FDOTto provide for efficient operations at the TMC. So from the beginning, it was FDOT’s goal to use a single integrated platform that can help communicate with all devices and manage our system. Provides users withsingle familiar interface to work with Allows TMC operators to perform their task efficiently. Also, FDOT wanted an automated software that has the capability to detect incidents and post messages on dissemination devices with minimal input from operators. In order to meet this requirement, FDOT needed to have an integrated software platform.
- SunGuide can: Communicate with all ITS devices, Manage devices, Ability to provide diagnostic capability to identify problems within the device. SunGuide can manage several devices (the below list is not comprehensive): Dynamic message signs, Cameras, Vehicle sensors, Highway advisory radios, Road weather information systems, Ramp meters, Video wall controllers, and Safety barriers.All devices along the limited access facilities are managed by SunGuide. Some of these devices use national standards like NTCIP and some legacy devices use vendor specific protocols. But independent of the protocol and standards, SunGuide can talk to both newer devices and the legacy devices deployed here in Florida.
- The traffic management center operators manage traffic by: Scanning cameras on the video wall, Coordinating with service patrol units and law enforcement officers
- SunGuide software offers automated incident detection. SunGuide monitors traffic data from vehicle sensors in real-time. If the traffic speeds along a roadway goes below a certain threshold, the operator is alerted. The drop in traffic speeds could be either due to crashes or typical peak hour congestion. FDOT messages on dynamic message signs and 511 system for congestion as well.Also, on the SunGuide map, the traffic speeds along the roadway is shown using different color schemes. This is a fairly common practice in the industry now. So the SunGuide map offersa comprehensive view of the network and allows operators to view which roadway segments are slowing.Monitoring video feeds – Some of FDOT regions use a vendor product to monitor video feeds from cameras and these can detect stopped vehicles. This product is interfaced with SunGuide, so if a stopped vehicle is detected, SunGuide is able to alert the operator. SunGuide is also integrated with Computer Aided Dispatch system or the CAD system that Highway Patrol uses to enter incidents. This allows the TMC to view the incidents that highway patrol just entered. The CAD system only sends non-sensitive / traffic information to the SunGuide system. This is customizable so SunGuide deployment can choose which roadways and event types they would like to receive information on.
- Steps taken by the TMC operator after detecting or being notified of incident: Verify the incident using camera Identify the Dynamic message signs in the vicinity, and determine the text to post on these signs. Go through the same process with Highway Advisory radios, if there are any. Post this message on 511 system. If there are any service patrols in the vicinity, notify them This is a significant amount of work that the operator has to do for a single event. Now imagine doing this for multiple events at the same time during afternoon rush hour.
- How can SunGuide help with event management. Event management is one of the most crucial aspects of any ATMS software system. SunGuide has a comprehensive approach towards event management.The SunGuide software automatically: Picks the DMS or HARs in the vicinity and selects the text that needs to be used on these devices. Recommends the text to be sent to 511 system. Recommends text to send to the TMC email group. For Connected Vehicle technology (we will discuss in future slides), Picks road side equipment and recommends text to be sent.All of this can be disseminated by the software with one click from the operator approving the response plan. In fact, in some of FDOT regions, TMC operators never have to manually type any message on the DMS as messages are typically recommended by the software or they use messages from the pre-defined message library.
- In Florida, we call Service Patrols as Road Rangers. Service Patrols are an important part of incident management. They help law enforcement clear incidents from the travel lanes. They also help stranded motorists. They patrol the limited access facility and work in close coordination with traffic management center.
- SunGuide can work with service patrol systems as well. The service patrol trucks can be located in real time on the SunGuide map. The SunGuide map really acts as a single screen that offers comprehensive information for TMC operators. TMC operator can get detailed information on a service patrol vehicle by clicking on it. Also, TMC operator can create geofence for each service patrol vehicle that defines the segments of roadway that they need to cover. You can see the geofence on the slide in blue. If they are outside this region, the vehicle icon will have a red circle around it to highlight that.
- With the advent of technology, now-a-days, agencies can have computing devices that could be mounted on the road ranger vehicle itself. These devices communicate with the service patrol systems that in turn communicate with the TMC and the SunGuide software. Within Florida, most of our regional TMCs equip their service patrol vehicles with computing devices. The next three slides show three different service patrol systems that we use here in Florida.
- This is used in the Ft. Lauderdale region. Uses ruggedized tablet with an application that was developed by FDOT. Highly interactive application.As seen on slide, some features include: It has the login screen, it allows users to enter events instead of calling it in or even add details to an existing event that the operator entered. There are more features not discussed in this presentation.
- This is a vendor software. It runs on a ruggedized laptop. This also offers a comprehensive set of features for the road rangers. As you can see these applications are highly interactive. In this, you can either use touch screen or use the keyboard to enter information.
- Using smartphones instead of tablets or laptops. The application was developed by FDOT. This is currently being used in the Jacksonville region. It has almost the same features that the previous two applications have. It also communicates in real-time with the TMC and SunGuide software as the other two. In summary, most service patrol vehicles have computing devices in them. It is becoming more and more common. It is important for the ATMS software to communicate with it in real-time. It doesn’t matter what service patrol system is used. However, it is important for the ATMS software to be flexible enough to communicate with any one of them. Also, it is important that the ATMS software not limit the user’s choices.
- SunGuide software can receive data from third party data providers. FDOT currently receives third party data for weather and traffic to supplement the existing ITS infrastructure that has been deployed. SunGuide software can also push data out. FDOT pushes data in real-time to 511 system. If an agency has a separate traffic and incident data archival system, they may have to send data to that as well. SunGuide uses center-to center infrastructure that is based on nationally recognized TMDD standards.SunGuide provides command and control: Ability to control another TMC including control devices and manage events . Can control TMC using different ATMS software, as long as the ATMS software uses the TMDD standards allowing for interoperability.FDOT regions subscribe to traffic and incident data from adjacent TMCs. This allows them to monitor traffic conditions along boundaries of their region so they can be prepared for an incident that would spill into their jurisdiction.
- SunGuide allows user to create customized reports that can help TMCs manage the systems better. SunGuide has 60 different report templates including (but not limited to) reports on ITS device health and status, incident performance measures and service patrols.FDOT has found the reports to be valuable. Helps users present information to upper management in a easy to comprehend manner.
- In Connected Vehicle technology, vehicles act as sensors and can provide information either to other vehicles or to the infrastructure on the side of the road which can in turn transmit the information to TMC. The vehicles use Dedicated Short Range Communication (aka DSRC) technology to communicate with other vehicles or infrastructure. FDOT has integrated the connected vehicle technology within SunGuide. Use the connected vehicle data to determine what the speeds are on each roadway segment. Broadcasts information directly to the vehicles from TMCs. These are called traveler advisory messages. This can supplement the existing set of dissemination devices that TMCs use like DMS, HARs and 511 system. TMCs can send messages about a crash that is upstream or could inform about congestion, directly to the vehicle.
- Florida DOT has deployed the connected vehicle technology in the Orlando region. 25 miles approx. of limited access and arterial facilities covered with connected vehicle technology. 28 road side equipment that werereceived from USDOT are installed. 33 Lynx buses and I-ride trolley’s are equipped with in-vehicle devices. FDOT receives the data from these vehicles in real-time at the Orlando TMC. Florida DOT is the first agency to have a production deployment. There are some other deployments in US but they are test beds. Unlike Florida, their data is not sent to a traffic management center or their deployments are not integrated within the TMC infrastructure and software system that TMCs use to make day-to-day decisions.
- ATMS is becoming an integral part of traffic operations in the nation. Florida has developed an advanced ATMS system that manages diverse set of ITS devices and provides incident management support. SunGuide offers significant automation of many features and is highly customizable. FDOT continues expand the software to further improve the features. The software is available for other states free of charge to use if any one is interested.
