Problems solved by technology

[0003] Nowadays, it is not enough to manage the overloading of multi-vehicle models on expressways and general arterial roads. It is far from enough to limit it to fixed weighing. Vehicle queuing congestion phenomenon, the management point is forced to release all vehicles in severe congestion, which not only caused a certain amount of economic loss, but also caused a large number of seriously overloaded vehicles to escape from the law. Real-time adjustment of the overload management threshold set by the overload management point equipment in real-time changing conditions, which can not only effectively limit severe overload, but also effectively prevent or alleviate traffic jams

Embodiment 1

[0056] The dynamic detection method for various types of trucks in this embodiment is selected to be carried out at the Jingwang Road toll station of Jincang Expressway.

[0057] The first step, preparatory work

[0058] The basic situation of this road section is that the Jingwang Road section of Jincang Expressway is two-way four-lane, the design speed of trucks is 60-100km / h, and the average speed during congestion is 50-80km / h. There are six toll lanes in this toll station , two entrances and four exits. The statistical result of the annual traffic status data at the entrance of the management point is: the annual passenger car traffic volume at the entrance of the expressway toll station is 12 million, and the truck traffic volume is 7 million. Among them, the proportions of 1 to 5 types of vehicles are: 30%, 10%, 10%, 30% and 20%, and the load conditions of 1 to 5 types of vehicles to be inspected at this management point are: the normal loading ratio is 35% 23% within...

Embodiment 2

[0103] Except that the sensor in the self-adaptive dynamic weighing system is to excavate a trench with a length of 2.0m, a width of 10mm and a depth of 1.5m under the ground 12mm of the overload management point, wires are wound along the trench, and the This constitutes a square inductance coil with a size of 2.0m×1.5m, and the others are the same as in Embodiment 1.

Embodiment 3

[0105] Select the traffic data at the entrance of the overload management point of the Machang section of the National Highway G104, and use various types of dynamic detection methods for trucks.

[0106] The first step, preparatory work

[0107] The basic situation of this road section is that the Machang section of National Highway G104 is two-way four-lane, the design speed of trucks is 40-80km / h, and the average speed during congestion is 20-60km / h. The statistical result of the annual traffic status data at the entrance of the management point is: the annual passenger car traffic volume at the entrance of the expressway toll station is 1.6 million, and the truck traffic volume is 4.4 million. Among them, the proportions of 1 to 5 types of vehicles are: 25%, 20%, 25%, 5% and 25%, and the load conditions of 1 to 5 types of vehicles to be inspected at this management point are: the normal loading ratio is 30% 20% within 20% of overload, 25% of overload of 20% to 40%, 14% of...

Abstract

The invention discloses a dynamic detection method for wagons of multiple vehicle types, and relates to the management of passing vehicles from management points. The dynamic detection method comprises the following steps of: knowing a basic condition of a dynamic detection road section of multiple vehicle types of required wagons in primary stage, and carrying out data statistics on a passing condition at a management point inlet; setting an overcapacity management point at a speedway toll station or a general arterial highway, wherein the overcapacity management point is an inlet adaptometer overcapacity management point; carrying out predetection on the vehicle passing information and vehicle overcapacity information of the inlet of the overcapacity management point; processing the pre-detected vehicle passing information, establishing an adaptometer dynamic threshold detection model as follows: theta i'=theta i+ lambda.omega i.detha i, i=1, 2....,5, and carrying out dynamic detection according to the work flow. The method provided by the invention is suitable to administrate distributed speedway of different vehicle types or general arterial highway road section overcapacity problem, the relation of blocking in the overcapacity detection station and overcapacity effective management is effectively processed, practical traffic information of roads in China is fitted, and the maximization of socioeconomic performance is realized.

Description

technical field [0001] The technical solution of the present invention relates to the management of passing vehicles at the management point, in particular to a dynamic detection method for various types of trucks. Background technique [0002] With the rapid development of freight traffic, the management of overloading of multiple vehicles on expressways and trunk roads is becoming more and more important. However, at this stage, the research and development of dynamic detection methods for multi-vehicle overloading is limited to the technical performance of weighing equipment and improving the accuracy of weighing equipment. CN200710067150 discloses a fixed vehicle dynamic weighing system, which pre-checks the axle load and total weight of passing vehicles. CN200910186130 discloses a dynamic weighing system scheme and equipment for expressway toll stations. According to this scheme, the scale platform selected should be placed along the driveway, and one side of the scale...
