3 Terms and definitions
The terms and definitions, as defined in GB 5768.3 and GB/T 42517.1-2023, as well as
the following terms and definitions, apply to this document.
3.1
Ordinary intersection
A level intersection that does not allow motor vehicles to pass through side roads,
in the inbound and outbound directions.
3.2
Complex intersection
A level intersection that allows motor vehicles to pass through side roads, in at least
one inbound or outbound directions.
4 Framework data model
4.1 Element model
The description of the element model, the theme of the element, the conceptual model
shall comply with the provisions in 4.1 of GB/T 42517.1-2023.
4.2 Coordinate frame system
The coordinate frame, time system, coordinate expression, etc. shall comply with the
provisions in 4.2 of GB/T 42517.1-2023.
4.3 Accuracy
The absolute accuracy, relative accuracy, accuracy index of the electronic road data
model for intelligent driving shall comply with the provisions in 4.3 of GB/T 42517.1-
2023.
4.4 Range of expression
The expression range of the uncontrolled access road on the intelligent driving
electronic road data model shall comply with the provisions in 4.4 of GB/T 42517.1-
2023.
4.5 Expression of general attributes of roads
The positive and negative value requirements of longitudinal slope, curvature,
transverse slope, heading shall comply with the provisions in 4.5 of GB/T 42517.1-
2023.
Ordinary intersections shall provide a lane geometric topological relationship table, to
record the inbound and outbound connections of the lane-level geometric paths in the
intersection; reserve a traffic status ID interface, to facilitate the expansion of
subsequent phase information. See Table 2, for the simplified connection geometry and
topological relationship of ordinary intersection lanes.
5.4.2.3 Maximized geometric connection of lanes at ordinary intersection
In the same direction of entry and exit in the intersection, all the entry lanes and exit
lanes have lane-level path connections, meanwhile the connected lanes are not capped
in the intersection, which is the basic principle of maximizing the geometric connection
of ordinary intersection lanes. The specific principles of connection are as follows:
a) When the number of exit lanes is an integer multiple of the number of entry lane,
each entry lane is allocated the same number of exit lanes, as per the multiple;
b) When the number of exit lanes is greater than the number of entry lanes and cannot
be divisible, the principle of equal division of entry lanes is adopted first, then the
remainder is added from right to left for each entry lane;
c) When the number of exit lanes is less than the number of entry lanes and cannot
be divisible, the principle of equal division of the exit lanes is adopted first, then
the remainder is added to each exit lane from right to left.
d) After the above number of lanes are allocated, when the number of exit lanes is
more than the number of entry lanes, each entry lane and exit lane are assigned
connection relationships from left to right, according to the number of exit lanes;
e) After the number of lanes above is allocated, when the number of exit lanes is less
than the number of entry lanes, each entry lane and exit lane are assigned
connection relationships from left to right, according to the number of entry lanes;
f) The geometric drawing of lanes in intersections shall meet the requirements of c),
d), e) of 5.4.2.2.
The schematic diagram of maximizing the connection of lanes at ordinary intersections
is as shown in Figure 4.
5.5.2.2 Simplified geometric connection of lanes at complex intersection
Lane geometric connections between main and auxiliary roads shall be established in
complex intersections, that is, any direction of a road (going straight, turning right,
turning left) can drive into the main road and auxiliary road of the opposite road, which
shall meet the following principles.
a) The connection rules between main roads and main roads, auxiliary roads and
auxiliary roads, including going straight, turning left, turning right, etc., shall
meet the requirements of 5.4.2.2.
b) When the main road is connected to the auxiliary road, the two situations are as
follows:
1) In the straight direction, the rightmost straight lane of the main road is
connected with the leftmost lane of the auxiliary road;
2) In the left-turn direction, the rightmost left-turn lane of the main road is
connected with the leftmost lane of the auxiliary road.
c) When the auxiliary road is connected to the main road, the two situations are as
follows:
1) In the straight direction, the leftmost straight lane of the side road connects
with the rightmost lane of the main road;
2) In the right turn direction, the leftmost right-turn lane of the side road connects
with the rightmost lane of the main road.
The simplified connection diagram of lanes at complex intersections is as shown in
Figure 7.
b) No.
