Description
Technical Field
[0001] The present invention relates to the technical field of expressways, and in particular to a separated lane expressway. Background Art
[0002] As the expressway network continues to expand, separated lane highways, as an advanced traffic organization method, optimize lane segmentation and management through physical separation facilities, significantly improving driving safety and efficiency. Specifically, separated lane highways can effectively reduce conflicts between different types of vehicles and driving demands. For example, by providing separate passenger and freight lanes, they ensure that passenger cars and trucks can travel safely without interfering with each other, greatly improving the driving experience. However, although separated lane highways have a significant effect in improving driving efficiency and safety within a single road section, in actual application, it has been found that this lane design lacks effective guidance solutions at key nodes such as entering and exiting highways and service areas. Current separated lane designs are mostly optimized within a single direction, without fully considering the complex traffic environment at highway entrances and exits and service areas. This lack of targeted lane separation has led to traffic congestion and safety hazards. Therefore, a new technical solution is urgently needed that can maintain the original advantages of separated lane highways while further optimizing traffic management at highway entrances and exits and service areas, ensuring smooth and safe vehicle entry and exit, thereby improving the operating efficiency and safety of the entire highway system. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the existing technology. On the basis of maintaining the original advantages of separated lane highways, it further optimizes the traffic management of highway entrances and exits and service areas, ensures the smooth and safe entry and exit of vehicles, and thus improves the operating efficiency and safety of the entire highway system.
[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A separated lane highway comprises a passenger lane, a truck lane, a median, an expressway entrance, and a service area, wherein the passenger lane and the truck lane are separated by a median, the expressway entrance connects the passenger lane and the truck lane, and the service area connects the truck lane. A front connecting entrance is provided between the passenger lane and the truck lane near the entrance to the service area, and a rear connecting entrance is provided between the passenger lane and the truck lane near the exit of the service area, wherein both the front connecting entrance and the rear connecting entrance connect to diversion lanes on the near sides of the passenger lane and the truck lane. The entrance and exit of the expressway are connected to the passenger lane and the truck lane through entry and exit lanes. The entry and exit lanes include roadbed lanes and bridge lanes. The end far from the expressway entrance is connected by the bridge lane, and the end close to the expressway entrance is connected by the roadbed lane.
[0005] Furthermore, the passenger lane and truck lane are 2-4 lanes in one direction, and each lane is 3.75m wide.
[0006] Furthermore, a bridge lane may be used at the exit of the service area to directly connect to the passenger vehicle lane.
[0007] Furthermore, speed reduction markings are used on the passenger lanes or truck lanes at the entrances and exits, front connecting entrances, rear connecting entrances, and entry and exit lanes of the service area.
[0008] Furthermore, guide lines are provided between the entrance and exit of the service area, the front connecting entrance, the rear connecting entrance, and the entrance and exit lanes and the passenger lanes or truck lanes.
[0009] Furthermore, the front connecting port is connected from the guide lane in the passenger car lane to the guide lane in the truck car lane, so that the number of lanes in the passenger car lane is reduced by one and the number of lanes in the truck car lane is increased by one; The rear connecting port is connected from the guide lane in the truck lane to the guide lane in the passenger lane, so that the truck lane is reduced by one lane and the passenger lane is increased by one lane.
[0010] Furthermore, the speed limit of the passenger lanes or truck lanes at the entrances and exits, front connecting entrances, rear connecting entrances and entry and exit lanes of the service area is 80km / h, and the front end is restricted by a gantry and a speed limit camera.
[0011] Furthermore, the distance between the front connecting port and the service area entrance is 3km-5km, the distance between the rear connecting port and the service area exit is 3km-5km, the interval speed limit at the starting and ending points of the lane between the front connecting port and the service area is 80km / h, and the interval speed limit at the starting and ending points of the lane between the rear connecting port and the service area is 80km / h.
[0012] Furthermore, the right lanes of the passenger lanes, truck lanes, roadbed lanes and bridge lanes are emergency lanes.
[0013] Furthermore, the isolation zone is a concrete guardrail or a green belt.
[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention has the following significant beneficial effects: 1. Optimize traffic organization and improve operational efficiency: By setting up front and rear connecting ports, passenger and truck lanes can be flexibly connected at the entrance and exit of the service area. This effectively solves the lane change problem when vehicles enter and exit the service area, avoids traffic congestion caused by lane mismatch, improves the efficiency of vehicles entering and exiting the service area, and thus improves the operational efficiency of the entire expressway system. Among them, the design of the diversion lane can improve traffic safety and reduce conflicts in lane changes when the passenger lane and the truck lane are connected. Under the conditions of the subsequent 3km-5km lane changing space and the speed limit of 80km / h, it is possible to safely enter the service area diversion lane or safely enter the passenger lane from the truck lane. The dynamic lane adjustment of the diversion lane provides the driver with a clear path, reduces the difficulty of operation and the risk of misjudgment, avoids vehicles changing lanes near the entrance and exit of the service area, and reduces the risk of collision and scratch accidents. 2. Enhance traffic safety and reduce accident risks: Deceleration markings and guide lines are set up at the entrances and exits of service areas, front connecting entrances, rear connecting entrances, and entry and exit lanes to guide vehicles to drive in a standardized manner, reduce the phenomenon of vehicles changing lanes at random and driving in a chaotic manner at these key nodes, reduce the probability of traffic accidents, and ensure the safety of vehicles and personnel. 3. Flexible entry and exit lane design to adapt to complex environments: The entry and exit lanes adopt a combination of roadbed lanes and bridge lanes. The end far from the highway exit is connected by the bridge lane, and the end close to the highway exit is connected by the roadbed lane. This design can better adapt to the complex traffic environment of highway entrances and exits and service areas, ensuring the smooth entry and exit of vehicles. 4. Scientific speed limit management and standardized driving order: Speed limits are imposed on the passenger lanes or truck lanes at the entrances and exits of the service area, the front connecting port, the rear connecting port, and the entry and exit lanes, and restrictions are implemented through gantries and speed limit capture cameras. At the same time, interval speed limits are set at the starting and ending points of the lanes between the front connecting port and the service area, and between the rear connecting port and the service area. This effectively regulates the speed of vehicles in these key areas, maintains good driving order, and facilitates the interconnection of passenger lanes and truck lanes to facilitate vehicles in the passenger lanes to enter the service area.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0021] Example 1
[0022] like Figure 1-6 As shown, the present invention provides a technical solution: a separated lane highway, comprising a passenger lane 1, a truck lane 2, a dividing strip 3, a highway entrance 4 and a service area 5; Passenger lane 1 and truck lane 2 are separated by a median strip 3. This separation effectively prevents interference between buses and trucks during driving, improving driving safety and road traffic efficiency. Expressway entrance 4 (including expressway entrance and exit) connects passenger lane 1 and truck lane 2. Vehicles can enter the corresponding lane from expressway entrance 4 according to their type. Signs and guide signs are installed at the corresponding entrances. Service area 5 connects to truck lane 2.
[0023] A front connecting port 6 is provided between the passenger lane 1 and the truck lane 2 near the entrance of the service area 5 to connect them, and a rear connecting port 7 is provided between the passenger lane 1 and the truck lane 2 near the exit of the service area 5 to connect them. Both the front connecting port 6 and the rear connecting port 7 are connected to a guide lane 8 on the near side of the passenger lane 1 and the truck lane 2. The provision of the guide lane 8 can guide vehicles to change lanes safely and orderly, thereby reducing traffic accidents caused by lane changes.
[0024] The entrance and exit of highway exit 4 are connected to the passenger lane 1 and the truck lane 2 through the entrance and exit lanes 9. The entrance and exit lanes 9 include a roadbed lane 91 and a bridge lane 92. The end away from highway exit 4 is connected by the bridge lane 92. This design can avoid excessive cross-interference between vehicles and other ground traffic facilities near the highway exit; the end close to highway exit 4 is connected by the roadbed lane 91, which facilitates the smooth entry and exit of vehicles.
[0025] Example 2
[0026] like Figure 1-6 As shown, passenger lane 1 and truck lane 2 are one-way 2-4 lanes respectively. Lanes 2-4 are paved and designed according to the actual traffic volume. The width of each lane is 3.75m, which meets the national highway lane design standards and can meet the vehicle traffic needs under different traffic volume conditions.
[0027] Preferably, a bridge lane 92 can be selected at the exit of the service area 5 to directly connect to the bus lane 1. This optional solution can be flexibly designed according to actual terrain, traffic flow and other factors to improve the adaptability and efficiency of road construction. This design can be used in large service areas and service areas with large traffic volume to avoid the need for small passenger cars to first enter the truck lane 2 and then pass through the connecting port 7 to enter the bus lane 1.
[0028] The passenger lane 1 or truck lane 2 at the entrance and exit of service area 5, front connecting entrance 6, rear connecting entrance 7 and entrance and exit lane 9 are all equipped with deceleration markings. The deceleration markings can remind drivers to slow down in advance and ensure safe driving of vehicles in these special sections.
[0029] Guide lines are installed between the entrance and exit of service area 5, front connecting entrance 6, rear connecting entrance 7 and entry and exit lanes 9 and passenger lane 1 or truck lane 2. The guide lines can guide vehicles to drive along the prescribed route and avoid violations such as arbitrary lane changes and crossing of lanes.
[0030] The front connecting port 6 is connected from the guide lane 8 in the passenger lane 1 to the guide lane 8 in the truck lane 2, so that the passenger lane 1 is reduced by one lane and the truck lane 2 is increased by one lane. This design is to meet the need to enter the truck lane to go to the service area 5, while ensuring that the truck lane still has sufficient traffic capacity after receiving the passenger lane, and does not affect each other.
[0031] Similarly, the rear connecting port 7 is connected from the guide lane 8 in the truck lane 2 to the guide lane 8 in the bus lane 1, so that the truck lane 2 is reduced by one lane and the bus lane 1 is increased by one lane. This is to allow the bus to return to the bus lane 1 safely and smoothly after completing the relevant service in the service area 5 and continue driving without affecting the normal driving of vehicles in the bus lane 1. The speed limit on passenger lane 1 or truck lane 2 at service area entrance 5, front connecting entrance 6, rear connecting entrance 7, and access lane 9 is 80 km / h. This is achieved through the use of a gantry and speed limit cameras. The gantry can be equipped with traffic signs such as speed limit signs to remind drivers of the speed limit; the speed limit cameras can capture speeding vehicles, ensuring safe driving speeds in these special sections.
[0032] The distance between the front connecting entrance 6 and the entrance of the service area 5 is 3km - 5km, and the distance between the rear connecting entrance 7 and the exit of the service area 5 is 3km - 5km. The starting and ending points of the lane between the front connecting entrance 6 and the service area 5 are set with an interval speed limit of 80km / h, and the starting and ending points of the lane between the rear connecting entrance 7 and the service area 5 are set with an interval speed limit of 80km / h. Reasonable distance setting and interval speed limit can ensure that vehicles have sufficient reaction time and safe driving speed when entering and leaving the service area and entering the passenger bus lane 1.
[0033] The right lanes of passenger lane 1, truck lane 2, roadbed lane 91 and bridge lane 92 are emergency lanes. In emergency situations (such as vehicle breakdown, traffic accident rescue, etc.), the emergency lanes can provide passage and parking space for rescue vehicles and faulty vehicles, ensuring the road's emergency rescue capabilities.
[0034] The isolation belt 3 is a concrete guardrail or a green belt. The concrete guardrail has high strength and stability, and can effectively prevent vehicles from crossing the isolation belt and causing collision accidents; the green belt not only plays an isolation role, but also beautifies the road environment, absorbs noise and exhaust gas, etc.
[0035] When this separated highway is put into use, vehicles arriving at Exit 4: Bus driving process: Bus drivers follow the signs and select the entrance and exit lane 9 corresponding to the bus lane 1 to enter the highway. At the entrance and exit lane 9, the bus follows the guidance of the roadbed lane 91 and the bridge lane 92 and smoothly drives into the bus lane 1. During the driving process, the bus maintains the specified driving speed (usually 100- 120km / h, depending on the speed limit requirements of the road section). When a passenger bus needs to enter the service area 5, it should slow down in advance and follow the instructions of the deceleration markings and guide lines to pass through the guide lane 8 at the front connecting entrance 6, and change from the passenger lane 1 to the truck lane 2 (at this time, the passenger lane 1 is reduced by one lane, and the truck lane 2 is increased by one lane). After entering the service area 5, the passenger bus completes related services such as refueling and rest. When leaving the service area 5, the passenger bus passes through the bridge lane 92 at the exit of the service area 5 (if this solution is adopted) or other entry and exit lanes 9, and follow the guidance of the deceleration markings and guide lines to pass through the guide lane 8 at the rear connecting entrance 7, and change from the truck lane 2 back to the passenger lane 1 (at this time, the truck lane 2 is reduced by one lane, and the passenger lane 1 is increased by one lane). Then, it continues to travel on the passenger lane 1 until it reaches the destination and exits the highway from the corresponding highway exit 4.
[0036] Truck driving process: Truck drivers follow the signs and select the entrance and exit lane 9 corresponding to truck lane 2 to enter the highway. The truck travels at the prescribed speed (generally 80-100 km / h, depending on the speed limit requirements of the road section) in truck lane 2. When the truck needs to enter service area 5, it slows down in advance and drives directly into service area 5 according to the instructions of the speed reduction markings and guide lines. After completing refueling, maintenance, rest and other services at service area 5, the truck passes through the entrance and exit lane 9 at the exit of service area 5, follows the guidance of the speed reduction markings and guide lines, continues to drive in truck lane 2, and finally exits the highway through the corresponding highway exit 4.
[0037] Throughout the driving process: The distance between the front connecting port 6 and the entrance of the service area 5 is 3 km to 5 km, and the distance between the rear connecting port 7 and the exit of the service area 5 is 3 km to 5 km, which can provide and meet the needs of passenger cars changing lanes to enter the service area 5, or from the service area to the truck lane 2 and then enter the passenger lane 1; All vehicles must strictly abide by the speed limit of 80km / h at special sections such as the service area entrance and exit 5, front connecting entrance 6, rear connecting entrance 7 and entry and exit lane 9, and drive according to the deceleration markings and guide lines to ensure driving safety.
[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
