Introduction About me: > Kyle Rush • Software Developer – Leidos • Saxton Transportation Operations Laboratory (STOL) – Federal Highway Administration
About the tool: > U.S. DOT Funded & Developed Tool > Creation of SAE J2735 MAP Messages via a web application > Available for use by any interested parties > Under current development and enhancement at the STOL
Overview MAP Messages > Describe physical layout of an intersection or stretch of roadway in a digital form • Lanes and stop bars • Crosswalks • Signal group assignments • Allowed maneuvers > Lanes and other objects in message constructed as set of points connected by straight lines > Used by connected vehicles for safety critical applications > Standardized by SAE J2735
Overview MAP Tool > Provides a simple, web application UI to build MAP messages by drawing geometry on map tiles > Allows for configuration of data fields with descriptions, units, and min/max values > Able to generate actual binary output for broadcast at RSU > Tool is available at: https://webapp.connectedvcs.com/ > Support is available at: https://cvcs.samanage.com

MAP Creation Walkthrough Turner Fairbanks Highway Research Center https://webapp.connectedvcs.com/isd/
MAP Creation Summary 1. Create parent MAP 1. Reference point at center of intersection 2. Verified point at known accurate location 3. Configure intersection data (name, speed limit, etc.) 4. Save file to computer
1. Create child MAP 1. Load parent MAP created in 1 2. Draw vehicle lanes connecting to intersection, from stop bar backwards 3. Group vehicle lanes into approaches 4. Draw crosswalks 5. Fill in vehicle lane details 6. Fill in approach details 7. Fill in crosswalk details 8. Configure “connects to” values and signal groupings for all vehicle lanes 9. Save file to computer

MAP Encoding & MAP Validator
MAP Encoding Summary 2016 SAE Standard Message Type >
ISD = Unified Signal Phase and Timing (SPaT) + MAP used by Safety Pilot Program
>
MAP = Raw MAP message contents not suitable for broadcast
>
MAP + Frame = Raw MAP message contents wrapped in message frame, broadcast ready, recommended setting
>
SPaT = Raw SPaT message contents not suitable for broadcast
> SPaT + Frame = Raw SPaT message contents wrapped in message frame, broadcast ready Node Offsets >
Explicit = Double precision latitude/longitude coordinates at every point
>
Standard = Single precision latitude/longitude coordinates at every point
>
Compact = Uses smallest offset type that can be used for every point
>
Tight = Optimizes offset size on a point by point basis, produces smallest message, recommended setting
