Using Connected Vehicles to Improve Safety in Work Zones Transpo Florida 29 October 2012
Introduction Jim O’Neill GEWI Presentation2
Agenda GEWI Presentation3 About GEWI. Local Hazard issue and implications. Collecting probe data. Create warning messages. Encode and distribute TPEG messages. Present in-car warnings. Local Hazard Warning Demonstration. TPEG vs. RDS-TMC. Questions?
GEWI History GEWI Presentation4 Founded in 1992 Hagen Geppert & Dr. Karl Will Corporations in Germany, USA, and Singapore. Headquarter in Bernburg (Germany). Offices in USA, Singapore, UK, and Russia. Certified by ISO 9001:2001 since 1998.
Global Technical Perspective GEWI Presentation5
Traffic Market GEWI Presentation6
Local Hazard Issue – Work Zone Safety GEWI Presentation7 87,606 reported work zone accidents in 2010 in USA. Work Zone Injuries - 37,476 injuries in work zones in This equates to one work zone injury every 14 minutes (96 a day), or about four people injured every hour. Work Zone Fatalities: In 2010, there were 514 fatal motor vehicle crashes in work zones, resulting in 576 fatalities. These 576 fatalities equate to one work zone fatality every 15 hours (1.6 a day). Type of Crash: Of the 720 work zone fatalities in 2008, 41% of crashes were rear- end collisions (compared to 16% of all fatal crashes)
Implications GEWI Presentation8 Fatalities and injuries. Safety of maintenance staff working on-site. Damaged road side equipment (barriers, trailers, cars). Damaged private cars and trucks. Road blockages and long traffic jams. If we could increase driver’s awareness it would help avoid these issues!
GEWI Presentation9 Local Hazard Warning - Collecting Probe Data Local Hazard Warning ITS World Congress 2011, Special Session 08 Maintenance vehicles or trailers are equipped with GPS and GPRS capable devices. (http://www.traffic-tim.de/produkte/verkehrssicherheit/divan.html, German only) Position, bearing, and status is sent to a server monitoring all devices. Data records are forwarded to the control center. 10/17/20119
GEWI Presentation GEWI’s TIC software receives data records using DATEX2 Version2. Geo-matching of GPS data onto the road network. Creating traffic event messages with geo-matched location. Operators evaluate traffic event messages for their safety relevance. (can also be automated) Aggregate related messages into a new message for multiple lane closures (e.g. “two right lanes closed”). Creating Warning Messages 10 Processing LHW Data
GEWI Presentation11 TPEG over HTPP (THTTP). A THTTP Request is send to the server by the vehicle. The server gathers all relevant traffic event messages. Messages are then coded using TPEG TEC with DLR1 (AGORA-C). TPEG messages are packaged and send back to the vehicle through an THTTP Response. Distribute TPEG messages Local Hazard Warning ITS World Congress 2011, Special Session 08 10/17/201111

Current (RDS-TMC) vs Future (TPEG) GEWI Presentation14 RDS-TMC Traffic Message Channel (TMC) messages are broadcast over FM or Satellite using the Radio Data Channel (RDS) with encryption. Data can be regionalized by dynamically generating message cycles for individual regions. Priority can be given to urgent messages. Can only transmit 300 messages in 15 minutes. Only the Alert-C standard can be used to transmit traffic events. Events can only be referenced to TMC locations. Well established with many RDS-TMC receive devices available.
Current (RDS-TMC) vs Future (TPEG) GEWI Presentation15 TPEG TPEG can be broadcast over digital media such as DAB, HD, Satellite Radio, TCP/IP, and mobile telecoms (GPRS, UTMS) using TPEG over HTTP. Two way communication. Many applications supported to provide more robust information to traveler. Travel data can be location referenced to multiple location referencing methods. Conditional access: Provides for free or subscriptions services. High volume of messages may be transmitted (up to 20,000 per 15 minutes)
TPEG Applications GEWI Presentation16 TPEG Many applications already standardized: -Parking (PKI), -Road Traffic Message (RTM) -Traffic Event Compact (TEC) -Traffic Flow & Prediction (TFP), -Congestion & Travel Time (CTT) -Fuel Pricing Information (FPI), -Public Transport Information (PTI), Future: Road pricing, weather
GEWI Presentation17 More and more maintenance trailers/trucks will be equipped with GPS/GPRS modules. Vehicle manufactures incorporating TPEG capable navigation devices into their cars, e.g. BMW, Audi, … - and you can already buy these cars. The Local Hazard Warning Service was provisioned for service in TIC software already incorporates all the features necessary and as a COTS product it is cheaper than building your own. Connected Vehicles are Here
