Interface: Personal Information Devices for Travelers - Map Update System
Information Flow Definitions
intersection geometry (Planned)
The physical geometry of an intersection covering the location and width of each approaching lane, egress lane, and valid paths between approaches and egresses. This flow also defines the location of stop lines, cross walks, specific traffic law restrictions for the intersection (e.g., turning movement restrictions), and other elements that support calculation of a safe and legal vehicle path through the intersection.
map updates (Planned)
Map update that could include a new underlying static or real–time map or map layer(s) update. Map layers can include highways, major roads, streets, public transport routes, topography, points of interest, and regulatory information including turn restrictions and speed limits.
pathway map updates (Planned)
Pathway map updates that could include a new underlying static or real–time map or map layer(s) update. Map layers can include pedestrian routes, bike lanes, curbs, elevators, escalators, doorways, curb cutouts, indoor facilities, and other relevant features that impact pathway use.
