eSafety WG “Digital Maps” Ad Bastiaansen (Tele Atlas) - Chair Yiannis Moissidis (NAVTEQ) - Co-Chair The 4 th Plenary Session of eSafety Forum Thursday, 2 June 2005, Hannover “The Role of Digital Maps in deploying eSafety”

2 2 eSafety Objective Road safety is a major concern for all of us.….. In 2000, road accidents killed over people in the European Union and injured more than 1.7 million. EC policy goal:Reduce the number of road fatalities with 50% by Hypothesis:In-vehicle component technologies, infrastructure and digital map technologies will combine to achieve maximum gains in customer safety Questions:- Can road safety be improved using these three levers? - How can digital maps play a role in linking both in- vehicle and road infrastructure for improved customer safety?

3 3 Learning from Aviation … while today’s passengers benefit from instrument landing and collision avoidance systems. Result: Better Aviation Safety

4 4 How Has Road Safety Evolved?

5 5 The current role of Digital Map on the road? Digital maps currently support: in-vehicle safety systems Information services Traffic services

6 6 Today’s Emergency / Mayday Services Rapid response Vehicle locator capabilities Driver peace of mind

7 7 Information Services: Navigation

8 8 Personalized Traffic Information To destination: 37 minutes With Traffic: 51 minutes

9 9 Improving Autonomous Vehicle Safety Advanced Driver Assistance Systems (ADAS): In-vehicle systems increasing the comfort and safety of the driver On basis of sensor information Map enabled ADAS: The map as one of the sensors Three levels of assistance: –Informational: The vehicle informs the driver “The speed limit on this road is 45 miles per hour.” –Advisory / Warnings: The vehicle warns the driver: “You are going too fast for the curve ahead,” OR “You are leaving your lane.” –Intervention: The vehicle transitions the headlights in preparation for the curve ahead, OR applies the brakes as it approaches a stop sign or veers off road.

10 Speed Limit Warning Precise speed limit information in the map is used to notify drivers when entering a new speed zone Required: Speed limit information Speed Limit

11 Adaptive Front Lighting Map geometry is used to adapt the direction or width of the head light beams –When the road curves, the headlights’ may project beyond the road, rather than illumination the road where the driver needs it –Integration of digital map data allows headlights to track with the road Required: Accurate map geometry

12 Curve Speed Warning (CSW) Curve and speed information from the digital map allows a system to warn for dangerous speeds of pending road curvature Required: Accurate map geometry + speed limits View of the same curve from a digital map perspective: able to “see around the bend” View of a curve from the driver’s perspective

13 Transition Road Segment Correct Target Selection Road Infrastructure: Map Assisted Radar

14 Road Infrastructure: Forward Collision Warning STOP Value Added Map Data: - Geometry indicates the precise location (lat/long) of an intersection - Geometry also indicates all possible paths for target vehicle (Given current speed, equipped vehicle should only be going straight) Future Attributes: - Stop signs, stop lights, yield signs and situations where the driver must give right-of-way, can be uniquely identified at the point at which they occur Unknown vehicle Equipped vehicle Inattentive driver not reducing speed

15 Which eSafety Map is required ADAS map geometry: Increased navigation accuracy –5-25m -> 5m –Slope, banking –Curvature

16 Which eSafety Map is required Lane information –number, topology Speed limit information Priority regulations Coverage: Continental/Global Coverage Phased introduction from higher road classes only to also lower road classes

17 The eSafety Map Challenges How to realise the uniform European eSafety Map? –Extend current navigation maps fundamentally –Improve Map Data Quality fundamentally High investments required Solutions –Optimize data collection and processes: No final solution due to inherent latency problem –Optimize data flow from public to private sector: No immediate solution due to public sector variance –A combined solution is required –Clear map requirements to support eSafety The private mapping sector started: The eSafety map for the major roads

18 Deploying eSafety Attributes – here we are today Extended Lane Guidance Lane information in the digital map is used to guide drivers safely over complex intersections and complex motorway junctions Required: Lane information (number, connectivity, symbols, …) Speed limit information Enhanced Road Geometry Coverage: Continental/Global Coverage on major roads ONLY today Weather Dependent Speed Limit Time Dependent Speed Limit Weather Dependent Speed Limit (I.e. snow) …But…

19 Optimise Public Private data flow Private collection methods can only register existing information A direct information from the birth of the information to the map is required –Public authorities are in charge of the Birth –A Public-Private Cooperation is required Individual and cooperative efforts of both government bodies and private sector  Thus, eSafety Working Group 11 “Digital Maps”: Business Models European Projects Maps&ADAS (Prevent), SpeedAlert, EuroRoads and SafeMap: Technical implementation
