3 General Stipulations
3.1 Road traffic markings are transportation facilities constituted of various lines,
arrows, texts, patterns, elevation markers, physical markers, raised pavement markers
and delineators that are designated or installed on roads. Their effect is to convey
a) Allows crossing of roadway in opposite direction;
b) Allows crossing of roadway in same driving direction;
c) Tidal lane;
d) Roadway edge line;
e) Left-turn waiting line;
f) Intersection guidance marking;
g) Guidance lane line.

4.2 Marking that Allows Crossing of Roadway in Opposite Direction
4.2.1 When marking that allows crossing of roadway in opposite direction (also known
as crossing of road axis) is yellow dotted lines, it is used to separate traffic flows that
are driving in opposite direction. Generally speaking, it is set up at the center line of
roads. However, it is not restricted to the geometric center line of roads. Under the
circumstance of guaranteed safety, vehicles may cross the line to overtake other
vehicles on the road, or, make a turn.
4.2.2 In terms of roads whose width allows two-way driving of two (or more) motorways,
when line-crossing for overtaking and turning is allowed, marking that allows crossing
of roadway in opposite direction shall be designated.
5 Prohibition Markings
5.1 Classification of Prohibition Markings
5.1.1 Longitudinal prohibition markings include:
a) Prohibits crossing of roadway in opposite direction;
b) Prohibits crossing of roadway in same driving direction;
c) Marking prohibition marking.
5.1.2 Horizontal prohibition markings include:
a) Stopping line;
b) Stopping and give-way marking;
c) Deceleration and give-way marking.
5.1.3 Other prohibition markings include:
a) Non-motor vehicle no-drive zone marking;
b) Flow guidance marking;
c) Grid line marking;
d) Exclusive lane marking;
e) U-turn (turning) prohibition marking.
5.2 Marking that Prohibits Crossing of Roadway in Opposite
Direction
5.2.1 Marking that prohibits crossing of roadway in opposite direction (also known as
prohibits crossing of road axis) has three types: double yellow solid lines, yellow
dotted-solid lines and single yellow solid lines. It is used to separate traffic flows that
are in opposite direction; prohibit vehicles in two directions or one direction from driving
on or over the line. Generally speaking, it is set up at the center line of roads. However,
it is not restricted to the geometric center line of roads.
5.2.2 When double yellow solid line serves as marking that prohibits crossing of
roadway in opposite direction, it prohibits vehicles in two directions from driving on or
over the line. Generally speaking, it is designated on roads where there are two or
more motor vehicle lanes in one direction but no practical central divider. Except from
intersections or sections that allow vehicles to make left-turn (or U-turn), double yellow
solid line shall be continuously set up. The form of vibration marking may be adopted.
the recommended layout spacing is 30 cm ~ 50 cm. In addition, the surface
of the raised pavement marker shall have sufficient anti-slide performance.
7.1.4 The other performance of raised pavement markers shall comply with the
requirements in JT/T 390.
7.2 Delineators
7.2.1 Delineator is used to indicate the forward direction and edge contours of roads.
7.2.2 The setting of delineators has the following stipulations:
a) In terms of expressways, first-class highways, main lines of urban
expressways, and exit and entrance ramps or connecting roads of
interchanges, service areas and parking lots, delineators shall be
continuously set up.
b) In terms of second-class highways, third-class highways, and other roads and
sections, as required, delineators may be continuously set up on both sides
along the main line. In terms of small-radius curves, continuous turns, poor
range of visibility, and sections where roadside rushing-out accidents would
easily occur and where accidents have frequently occurred, in accordance
with other safety treatment measures, delineators shall be continuously set
up on both sides along the main line.
c) In terms of main straight sections of expressways, the spacing of delineator
setting is generally 50 m. When delineators are attached to fences, the set
spacing may be 48 m. In terms of first-class highways and main straight
sections of urban expressways, the spacing of delineator setting is generally
40 m. In terms of second-class highways, third-class highways and main
straight sections of other roads, the spacing of delineator setting is generally
30 m.
d) The spacing of delineator setting on curved sections may be selected in
accordance with the stipulations in Table 8, or, be properly thickened. The set
spacing of delineators on the start-stop segment outside the curved sections
is shown in Figure 111. If double or triple spacing is larger than 50 m, then,
the value shall be 50 m.

Intersection Marking Setting
B.1 General Principle
a) The setting of intersection markings shall aim at guaranteeing safe, orderly
and efficient intersection traffic; integrate the practical condition of intersection
and the practical characteristics of traffic flow in design and setting;
b) Exclusive lanes for left-turn and right-turn shall be actively developed;
c) In order to develop exclusive lanes at intersections, appropriate widened
intersections and appropriate lane width reduction shall be firstly considered.
When the above measures cannot satisfy the requirements, or when the
measures cannot be implemented due to restrictions, in order of priority, the
methods of reducing the width of central divider, reducing the width of central
divider and reducing roadway width, offsetting road axis and reducing
roadway width, reducing road shoulder or the width of non-motor vehicle lane
may be successively adopted to develop exclusive lanes at intersections.
B.2 Classification of Intersection Markings
In accordance with the set location, intersection markings may be classified into the
following two types:
a) Pavement markings in the exit and entrance area of intersections: in the exit
and entrance part of intersections, as required, set up various pavement
markings, such as: roadway boundary, guidance roadway, roadway guidance
arrow, and left (right) turn guidance marking, so as to clearly indicate the
driving location and forward direction of the traffic flow that drives into or drives
out of the intersections.
b) Pavement markings in intersections: “in intersections” refers to the
intersection area inside stopping line. In intersections, as required, stopping
line, stopping and give-way marking, deceleration and give-way marking,
crosswalk line, non-motor vehicle no-drive zone marking, central circle may
be set up, so as to indicate vehicles’ stopping location, and pedestrians and
non-motor vehicles’ passage location. Moreover, as required, markings like
left-turn waiting zone and flow guidance marking may also be set up, so as to
indicate motor vehicles’ trajectory in intersections, through which, the traffic
flow may be guided to smoothly and steadily pass the intersections.
Where,
N---within 1 cycle, the average number of left-turn vehicles, expressed in (PCS);
s---average headway, expressed in (m).
Intersections without signal control:
Where,
M---within 1 min, the average number of left-turn vehicles, expressed in (PCS).
In terms of the average headway (s) when left-turn vehicles are lining up, small-sized
vehicles may be 6 m; large-sized vehicles may be 12 m. If it is impossible to obtain the
mix-in rate of large-sized vehicles, then, s may be 7 m for unified calculation.
Under urban road environment, within the range permitted by all the conditions, make
sure to obtain the maximum length of left-turn exclusive lane. The length of gradient
section may be reduced, so as to increase the length of the lining-up section as much
as possible. Under highway environment, on the basis of guaranteeing sufficient length
of gradient section, necessary left-turn exclusive lane shall be set up.
B.3.2 Exclusive lane marking to right-turn
B.3.2.1 Generally speaking, under the following circumstances, right-turn exclusive
lanes shall be set up:
a) Intersections where the angle of intersection is acute angle;
b) When right-turn traffic volume is extremely large;
c) When the velocity of right-turn vehicles is extremely high;
d) When there are many right-turn vehicles and pedestrians on the crosswalk,
and vehicles waiting for right-turn have severely affected straight driving
vehicles.
B.3.2.2 An example of the set parameters of right-turn exclusive lane is shown in
Figure B.7.
Unit: centimeter
B.3.3.2 In the lane of level-crossing intersection entrance section, except from variable
guidance lane, there shall be guidance arrows that indicate the driving direction of each
lane. The specific setting is shown in the stipulations in 4.15.
B.4 Pavement Markings in Intersections
B.4.1 Crosswalk
B.4.1.1 The distance of pedestrians’ one-time road-crossing shall be controlled under
18 m. If it is above 18 m, then, safety island shall be set up in appropriate locations.
B.4.1.2 The minimum width of crosswalk at the intersection on arterial road shall be 4
m. In terms of relatively narrow highway intersection, the minimum width of crosswalk
is 3 m, which may be increased by the unit of 1 m in accordance with the specific
condition.
B.4.1.3 When it is necessary to forecast that there is crosswalk ahead, in the central
roadway before the crosswalk, set up crosswalk forecasting pavement marking. The
location of setting shall comprehensively consider vehicles’ stopping distance and the
visibility of night-time driving. Generally speaking, a crosswalk forecasting pavement
marking shall be set up at a distance of 30 m ~ 50 m before crosswalk and at 10 m ~
20 m interval before crosswalk. In accordance with the specific road conditions,
another crosswalk forecasting pavement marking may be repeatedly set up. When
crosswalk is located in front of the curved turning part or other locations with poor range
of visibility, forecasting marking shall be set up.
B.4.2 Stopping line
B.4.2.1 In principle, stopping line shall be vertical to road axis.
B.4.2.2 When there is crosswalk, stopping line shall be set up at 1 m ~ 3 m before
crosswalk.
B.4.2.3 The set location shall be able to be clearly recognized by vehicles that are
driving in the surrounding area of intersection.
B.4.2.4 The setting of stopping line shall not obstruct the driving of left-turn and right-
turn vehicles in the intersection.
B.4.3 Give-way marking
Give-way marking in intersections includes two types: stop and give-way marking, and
deceleration and give-way marking. The set parameters of stop and give-way marking,
and deceleration and give-way marking are shown in the stipulations in 5.6; the
principle of the setting is shown in GB 5768.2-2009.
