Detailed Description
The invention is further described with reference to the drawings, as shown in fig. 1:
the invention discloses an elastic passing method of a highway in severe weather, which comprises the following steps:
s1, dividing a target road section into an unaffected area, an affected transition area and an affected area;
s2, setting passing identification information for the vehicle; the passing identification information comprises a driving-in point and a driving-out point; the entry point and the departure point are both located in an unaffected area or an affected transition area;
s3, monitoring the weather change condition of the target road section, and adjusting the unaffected area, the affected transition area and the area range of the affected area according to the weather change condition;
s4, adjusting the entry point and the exit point according to the adjustment result of the step S3, so that the entry point and the exit point are both located in the adjusted unaffected area or the adjusted affected transition area range, and the vehicle passes through according to the adjusted entry point and the adjusted exit point;
s5, repeating the steps S3-S4 until the vehicle drives away from the target road section.
In this embodiment, a scene shown in fig. 2 is taken as an example for explanation, and the target road segment is sequentially divided into an area not affected by severe weather, an area less affected by severe weather (i.e., an affected transition area), and an area affected by severe weather according to the degree of the severe weather. The range of jurisdiction of a certain highway management company, namely the range of the target road section area, is started from the toll station 6. Wherein, toll station 1 low reaches are bad weather influence region, are bad weather influence weak region between toll station 3 and 1, are not influenced by bad weather region between 6 to 3. The traveling direction of the vehicle is from the toll booth 6 to the toll booth 5.
In this embodiment, in step S2, passing identification information is set for passing vehicles, specifically, taking a vehicle that a certain vehicle intends to pass through a highway from the toll station 6 as an example, a driver fills in identity information and license plate information at a client of the highway management system, and leaves a high-speed toll station, such as the toll station 1, to make a travel reservation. That is, the entry point of the vehicle is the toll booth 6, and the exit point is the toll booth 1.
The green code is obtained after the information is filled in and audited by the highway management system; if the toll station filled by the driver is the downstream toll station of the toll station 1, the driver will obtain the red code, and the driver will not be able to pass through the section of the highway or the destination needs to be refilled.
Further, the driver can enter the high speed by scanning the green code at the toll station 6, and the driver can exit the high speed at the toll station 1 or the toll station upstream of the toll station, so that one pass based on the pass code is completed. If the driver passes through the severe weather influence area and drives away from the downstream toll station of the toll station 1, the driver is considered to be in violation of rules and influences the credit (both the vehicle and the driver are influenced), when the passing code is used for the next time, the yellow code is automatically generated, the system audit will not pass, and the driver cannot pass through the section of the expressway under the severe weather condition during the punishment period. Wherein, the punishment times are determined by the manager.
In this embodiment, in steps S3 and S4, the travel range is flexibly adjusted by pushing the mobile phone client message as the adverse weather influence range is expanded or reduced. Taking the vehicle as an example, if the severe weather influence area is enlarged between the toll stations 2 and 1, the driver will be informed of driving away from the toll station 2 by means of short message or voice. If the driver still drives away from the toll station downstream of the toll station 1, it is considered as a violation, which affects his credit. If the severe weather influence area is reduced to a downstream toll station of the toll station 1, a driver is informed of continuing to drive to the downstream toll station to drive away in a mobile phone short message or voice mode; if the area of influence disappears completely, the driver will be informed of free travel.
In this embodiment, in order to ensure the safety of vehicle passing and improve the efficiency of vehicle passing, the vehicles need to be controlled to be released, so that the release time interval between released vehicles is h t And makes the release period of the released vehicle T.
As shown in FIG. 3, the toll station 3 is the boundary of the section with weak adverse weather influence, the toll station 6 is the toll station farthest from the adverse weather influence area, the oblique arrows represent the space-time trajectory of the vehicles, and the safety distance s must be kept between the vehicles in the section with weak adverse weather influence safe Driving; wherein a safety spacing s safe Determined according to specifications or experience of an administrator.
The release time interval h is determined according to the following formula t ：
wherein ,ssafe For safe separation between vehicles in areas of less severe weather influence, v f The average travel speed of the vehicle in the area with less severe weather influence.
And setting a release period T from the initial entry point of the target road section, wherein the release periods of other entry points are the same as the initial entry point. Specifically, the toll station 6 is the initial entry point of the target road segment, and then for the toll station 6, the release period T is determined according to the following formula:
wherein k is the number of entry points in the unaffected area, and Δ x i For the ith spacing, v, in the unaffected region c Average speed of travel over sections of road not affected by the area, P 0 Is a set value. Specifically, the value of k is 3, that is, the unaffected area includes toll stations 6, 5 and 4, which total 3 entry points; Δ x 5,6 To the 1 st spacing in the unaffected region, Δ x 4,5 To the 2 nd spacing in the unaffected region, Δ x 3,4 The 3 rd spacing in the unaffected area; said P is 0 The value is the number N of vehicles released by the toll station 6 6 Number of vehicles N 6 Is determined by the supervisor, and if the toll station is to be backlogged of fewer in-line vehicles, N is set 6 Become smaller, otherwise N 6 Becomes larger.
In order to meet the traffic demand and further ensure the traffic safety of the vehicles, the number of vehicles released from the entry point is limited, so that the number of vehicles is N. As shown in fig. 3, the toll booths 5, 4 and 3 may each be entry points, in particular, for the number N of vehicles released from the toll booths 5 5 ：
wherein ,
denotes rounding down,. DELTA.x 5,6 Is the distance between the toll booth 5 and the toll booth 6.
Number of vehicles N released from toll booth 4 4 ：
wherein ,
direction of expressionLower integer, Δ x 4,5 Is the distance between the toll booth 4 and the toll booth 5.
Number of vehicles N released from toll booth 3 3 ：
wherein ,
denotes rounding down,. DELTA.x 3,4 Is the distance between the toll booth 3 and the toll booth 4.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
