RSM is currently mapping a series of junctions within the Caltrans CV Testbed in Palo Alto 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information

Upon completion RSM will have a lane by lane, detailed view of over 2. 5 miles of road 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information

Challenge - how to communicate this new level of detail to vehicles 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information

Currently RSM builds up a lane by lane view of an intersection with a range of 200 meters from the center. 400 metres RSM can integrate any loop detector, traffic signal or radar information into a single view and process that onto a map view of the junction or relay it to a vehicle equipped to receive it in near real-time. But how do we communicate this new super accuracy to GPS systems that are not? 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information

How accurate is GPS? GPS satellites broadcast their signals in space with a certain accuracy, but what you receive depends on additional factors, including satellite geometry, signal blockage, atmospheric conditions and receiver design features/quality. For example, GPS-enabled smartphones are typically accurate within a 4. 9 m (16 ft. ) radius under open sky (view source at ION. org). However, their accuracy worsens near buildings, bridges, and trees. In short we currently cannot rely on GPS to deliver the lane level information required to accurately place the vehicle.

If RSM were to use GPS it may place the user in the wrong lane. At minimum causing driver confusion, at worst could lead to an accident. Other challenges include latency, communications lag between infrastructure and vehicle, and even vehicle size and position relative to the user. These multiple sources of confusion and error are unacceptable. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information

Garmin RSM must ensure that: 1. Data is in a format that can be easily understood by the end user 2. Data should be in a format that is intuitive and easy to understand Go Live 3. When I 2 V data is no longer available, the end user is returned to a view that they are accustomed to 1 The Junction 2 GPS Challenges 3 RSM solution Navmii 4 More information

Exiting RSM view The following breakdown is assuming the current limitations of GPS apps, which use a vector system and simplified graphics to display the barest information. As GPS improves we can increase the fidelity of our graphics accordingly. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5. Standard GPS view

Exiting RSM view An RSM-enabled I 2 V junction would provide the users a seamless transition from their current GPS view, to the RSM detailed view and back again to their GPS view. The following concept demonstrates the end user experience as they journey in and our of an RSM-enabled junction. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5.

As the end user approaches the intersection, the RSM interface will phase in and the road view will reduce in opacity. The standard vector road will be replaced by the individual lanes. The wider the lane, the greater the traffic. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5. Standard GPS view

Exiting RSM view The roads are color-coded based on traffic flow varying from green and thin for ideal route, to red and wide based on slowest moving lanes. Traffic signal cycles ahead are also shown as well as their duration and time remaining for the cycle. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5. Standard GPS view

1. Standard GPS view 2. Entering RSM view 3. RSM Information 4. Exiting RSM view As the user nears the signal the traffic cycle for each direction is shown. The blue dot shows the current time in the traffic cycle and the upcoming green. RSM will not show other vehicles or what lane they are in, even if possible. This would distract the driver. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5. Standard GPS view

The right turn is not shown in this case, however if there was a pedestrian crossing it would also have its own cycle. Once the driver passes the intersection, the traffic signal icons fade away. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5. Standard GPS view

Once the user has passed the threshold of the RSMenabled I 2 V zone, the view returns to it’s original GPS view. 1 The Junction 2 GPS Challenges 3 RSM solution 4 More information 5.
