Problems solved by technology
The distance between these two ground intersections is relatively short, generally 45 meters; there are straight lanes and left turn lanes on the middle road section, and the number of straight lanes in the middle road section is different from the number of straight lanes on the two side road sections. For example, the east entrance at the intersection on the right has 2 through lanes, while the west entrance in the middle section has 1 through lane, which may cause traffic jams for the through vehicles at the ground intersection, thus affecting its traffic efficiency. and from figure 2 It can be seen that the ground intersection of the interchange needs to be controlled by a three-phase signal, which may also affect the traffic efficiency of through vehicles at the ground intersection

The invention discloses an interchange road system and a signal control method for ground intersections thereof. The interchange road system comprises a primary road, a secondary road and ramps connecting the primary road and the secondary road. The primary road comprises a first road section, a middle road section and a second road section which are sequentially arranged in the east-west direction or the south-north direction and are all provided with a plurality of two-way lanes. The first ground intersection and the second ground intersection are formed at the joints of the primary road and the ramps. Two-way straight lanes on the primary road are crossed in the first ground intersection and form a first overlapping area. The two-way straight lanes on the primary road are crossed in the second ground intersection and form a second overlapping area. The vehicle running direction in a straight lane on the middle road section is opposite to that of a straight lane on the corresponding side of the first road section and the second road section. In this way, the through efficiency of straight moving vehicles at the ground intersections can be improved.
Description
technical field [0001] The invention relates to the technical field of traffic engineering, in particular to a signal control method for an overpass road system and a ground intersection thereof. Background technique [0002] With the development of urban economy and traffic, in order to alleviate traffic congestion, a large number of interchanges have appeared in various cities. As a common structure of interchange, diamond interchange is widely used in urban road construction. [0003] The main feature of the diamond interchange is to build a separate interchange on the main line, and the turning traffic needs to build a dedicated turning ramp, and all turning traffic on the turning ramp needs to pass through the ground intersection of the secondary road. The current common diamond interchange structure is as follows: figure 1 As shown, the phase sequence of its ground intersection is as follows figure 2 shown. The ground part of the diamond-shaped interchange include...
