### <a name="VehicleType"></a>VehicleType
This DE is a type list (i.e., a classification list) of the vehicle in terms of overall size. The
 data element entries follow the definitions defined in the US DOT Highway Performance Monitoring System (HPMS).
 Many infrastructure roadway operators collect and classify data according to this list for regulatory reporting needs.
 Within the ITS industry and within the DSRC message set standards work, there are many similar lists of types for
 overlapping needs and uses.

 - 0 - `none`:       Not Equipped, Not known or unavailable
 - 1 - `unknown`:    Does not fit any other category
 - 2 - `special`:    Special use
 - 3 - `moto`:       Motorcycle
 - 4 - `car`:        Passenger car
 - 5 - `carOther`:   Four tire single units
 - 6 - `bus`:        Buses
 - 7 - `axleCnt2`:   Two axle, six tire single units
 - 8 - `axleCnt3`:   Three axle, single units
 - 9 - `axleCnt4`:   Four or more axle, single unit
 - 10 - `axleCnt4Trailer`:        Four or less axle, single trailer
 - 11 - `axleCnt5Trailer`:        Five or less axle, single trailer
 - 12 - `axleCnt6Trailer`:        Six or more axle, single trailer
 - 13 - `axleCnt5MultiTrailer`:   Five or less axle, multi-trailer
 - 14 - `axleCnt6MultiTrailer`:   Six axle, multi-trailer
 - 15 - `axleCnt7MultiTrailer`:   Seven or more axle, multi-trailer

### <a name="Velocity"></a>Velocity
This DE represents the velocity of an object, typically a vehicle speed or the recommended speed of
 travel along a roadway, expressed in unsigned units of 0.02 meters per second. When used with motor vehicles it may be
 combined with the transmission state to form a data frame for use. A value of 8191 shall be used when the speed is
 unavailable. Note that Velocity as used here is intended to be a scalar value and not a vector.

 The value 8191 indicates that velocity is unavailable

&nbsp;&nbsp;&nbsp;&nbsp;**Unit:** _0.02 m/s_

### <a name="WaitOnStopline"></a>WaitOnStopline
This DE is used to indicate to the vehicle that it must stop at the stop line and not move past.

 If "true", the vehicles on this specific connecting maneuver have to stop on the stop-line and not to enter the collision area

WaitOnStopline ::= BOOLEAN
```

### <a name="ZoneLength"></a>ZoneLength
This DE is used to provide an estimated distance from the stop bar, along the lane
 centerline back in the lane to which it pertains. It is used in various ways to relate this distance value. When used with
 clearance zones, it represents the point at which the driver can successfully execute the connection maneuver. It is used
 in the Clearance Maneuver Assist data frame to relate dynamic data about the lane. It is also used to relate the distance
 from the stop bar to the rear edge of any queue. It is further used within the context of a vehicle's traveling speed to
 advise on preferred dynamic approach speeds.

 0 = unknown,
 The value 10000 to be used for Distances >=10000 m (e.g. from known point to another point along a
 known path, often against traffic flow direction when used for measuring queues)
