Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_SignalRequest <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
Remarks: Note that the integer value range of 1..10 has been extended to become 0..15 in a one byte octet
in the DSRC use of this item.
7.95 Data Element: DE_ObstacleDirection
Use: As a companion data element to Obstacle Distance, this data element draws from the output of a
forward sensing system to report the obstacle direction from the vehicle detecting and reporting the
obstacle. The data is expressed in degrees as azimuth relative to forward direction of vehicle.
ASN.1 Representation:
ObstacleDirection ::= Heading -- Use the header DE for this unless it proves different.
XML Representation:
<xs:simpleType name="ObstacleDirection" >

Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
7.96 Data Element: DE_ObstacleDistance
Use: This data element draws from the output of a forward sensing system to report the presence of an
obstacle and its measured distance from the vehicle detecting and reporting the obstacle. This information
can be used by road authorities to investigate and remove the obstacle, as well as by other vehicles in
advising drivers or on-board systems of the obstacle location. Distance is expressed in meters.
ASN.1 Representation:
ObstacleDistance ::= INTEGER (0..255) -- LSB units of meters
XML Representation:
<xs:simpleType name="ObstacleDistance" >
<xs:annotation>
<xs:documentation>
LSB units of meters
