The invention discloses a vehicle-mounted card type highway traffic flow statistics and traffic jam forecasting method. A vehicle-mounted card (1) and a plurality of electronic base stations (2) mounted on each section of a highway are used in the method. The electronic base stations (2) communicate with the passing vehicle-mounted card (1) through short-distance telecommunication, and the card number, the vehicle type, the driving direction and the passing time of the vehicle-mounted card are obtained, subjected to statistics and sent to a superior center through a long-distance radio data transmission circuit in a timed, quantified or remote control manner to serve as the bases for a traffic jam forecasting signal; the electronic base stations are low in power consumption and small in size, can be conveniently mounted on each section of the highway according to the traffic flow monitoring requirements, and can work in all weathers without weather environment influence; the superior center can timely obtain or take the traffic flow of each monitoring point and send out a traffic jam forecast to a highway administration department according to a set traffic flow threshold.

The invention discloses a second-hand car pricing optimization method, which comprises the following steps: S11, obtaining the vehicle type information of the second-hand car to be priced input by a user; S12, according to the input vehicle type information, adopting an estimation model, calculating and obtaining the estimation value of the second-hand vehicle; S13, selecting the corresponding objective function from the objective function library, obtaining the boundary conditions of the objective function input by the user, optimizing calculation according to the set optimization algorithm and the estimated value obtained by calculation, and calculating to obtain the optimal price which maximizes the objective function as the second-hand vehicle pricing. As that estimate value of the second-hand vehicle is obtained by adopt an evaluating model, the objective function is also used to optimize the calculation according to the estimated value of the used car. As the optimal pricing of second-hand car, the method can optimize the pricing of second-hand car based on the dealer's situation, and can obtain more accurate pricing, which can be widely used in second-hand car pricing optimization industry.

The invention provides a travel application information display method, device and equipment. The travel application information display method comprises the steps of obtaining travel information of auser; if the estimated cost data of the current available vehicle type is obtained according to the travel information, displaying an online car-hailing order interface, wherein the estimated cost data of the current available vehicle type indicates the estimated cost range for N online booked vehicles, N is an integer greater than 1, and the online booked vehicle order interface comprises the estimated cost data of the current available vehicle type. According to the travel application information display method provided by the invention, the estimated cost data for the N types of currentlyavailable vehicle types can be obtained, the flexibility of online car-hailing reservation is improved, and the user experience is improved.

An embodiment of the invention relates to the technical field of data analysis, in particular, a method for analyzing vehicle source data, a device and an electronic equipment, which is applied to theserver in the platform of selling good cars, the server prestores a real-time updated vocabulary, The method comprises: Get plain text information, Splitting plain text information to get multiple lines of information, Extract the key information from each line of information, Look in the thesaurus for brand information, if present, recording the brand information and deleting the brand information from the plain text information, Count up all the cars under the brand information, Find out whether vehicle system information exists in all vehicle systems; if so, record the vehicle system information and delete the vehicle system information from plain text information; find out whether there are vehicle types corresponding to vehicle system information and target guidance price informationin the thesaurus; if so, find out the preferential price of the vehicle type and display the vehicle type and preferential price. Accurate vehicle source information can be obtained by this method.
