Stop line

The drawings on this page use left-hand traffic, as in Japan: vehicles drive on the left side of the road. For right-hand traffic, swap left and right. In the map drawings, a colored area is a Lanelet, and a line with dots is a Linestring and its points.

Requirements#

vm-02-01 Stop line alignment#

Detail of requirements #

Place the Linestring (type:stop_line) for the stop line on the edge of the white line that the vehicle reaches first.

Refer to Web.Auto Documentation - Creation and edit of a stop point (StopPoint) for the method of creation in Vector Map Builder.

A vehicle drives on a two-lane road toward a white stop line that crosses its lane.Stop line
A painted stop line across the lane of the vehicle.
Supplemental information #

A stop_line Linestring alone does not stop the vehicle. A Regulatory Element must refer to it. For a stop line with a stop sign, use a Regulatory Element (subtype:traffic_sign), as in vm-02-02. The stop line module of Autoware uses only the stop lines of traffic_sign Regulatory Elements with a stop_sign. Traffic lights, crosswalks, detection areas, and no stopping areas refer to their stop lines through their own Regulatory Elements.

Preferred vector map #

Preferred: the stop_line linestring lies on the edge of the white stop line that the vehicle reaches first.Linestringtype: stop_lineOn the near edge of the white line
The stop_line Linestring is on the near edge of the white line.

Incorrect vector map #

Incorrect: the stop_line linestring lies in the middle of the white stop line, not on its near edge.Linestringtype: stop_lineIn the middle of the white line
The stop_line Linestring is in the middle of the white line.

vm-02-02 Stop sign#

Detail of requirements #

Where there is no stop line on the road but a stop sign exists, place a Linestring as the stop line next to the sign.

Create a reference from a Lanelet (subtype:road) to a Regulatory Element (subtype:traffic_sign). Make this Regulatory Element refer to a Linestring (type:stop_line) with the role ref_line and to a Linestring (type:traffic_sign, subtype:stop_sign) with the role refers.

A stop sign stands next to the lane of the vehicle, and the road has no painted stop line.STOPStop sign, no painted stop line
A stop sign next to the lane, without a painted stop line.

Preferred vector map #

The road lanelet refers to a traffic_sign regulatory element. The regulatory element refers to a stop_line linestring next to the sign and to a traffic_sign linestring with the subtype stop_sign.STOPLinestringtype: stop_lineLinestringtype: traffic_signsubtype: stop_signLaneletsubtype: roadRegulatory elementsubtype: traffic_signregulatory_elementref_linerefers
The traffic_sign Regulatory Element refers to the stop line and to the stop sign.

None in particular.
