Embodiment Construction

[0063] Such as figure 1 A kind of bus arrival dynamic guidance method based on floating car shown, this method comprises the steps of following sequence:

[0064] S1. Construct a geospatial data system, divide and code road sections and bus stops, and use formula (1) to encode bus stops S h One-to-one association pairing with road section code Pi:

[0065] S h =f(P i )(i∈I, h∈H) (1)

[0066] Among them, i is the number of the current road segment; I is the total number of all road segments on the road network; H is the total number of all bus stops on the road network.

[0067] S2. Install GPS positioning equipment on the bus to form a bus floating vehicle, install guidance screen equipment at the bus station, use data communication and storage devices to obtain the dynamic parameter data of all bus floating vehicles in real time, and send the dynamic parameter data to the dynamic guidance processing server. The dynamic parameter data of the bus floating vehicle includes...

Abstract

The invention relates to a public bus arrival dynamic inducing method and device based on floating buses. The method comprises the following sequential steps that a geographic space data system is established, and road segments and public bus stops are partitioned and coded; dynamic parameter data of all the floating public buses are obtained in real time; road segment matching is conducted on real-time GPS coordinates of the floating public buses; the road segments matched with early point coordinates and later point coordinates of the floating public buses are obtained, and the driving routes of the floating public buses are obtained; allocation time and road segment travel time of the floating public buses at track road segment sets are calculated; correction travel time of road segments is obtained; passing road segment sets are obtained, the correction travel time of all the road segments is added, and the forecast arrival time of the floating public buses is obtained; an inducing screen device displays the forecast arrival time of the public buses in real time. By means of the public bus arrival dynamic inducing method and device based on the floating buses, the accuracy degree of public bus arrival time forecast can be increased, public travel is effectively dredged, and the information management and service level of a public bus system is increased.

Description

technical field [0001] The invention relates to the technical field of bus arrival time prediction, in particular to a method and device for dynamically inducing bus arrival based on a floating car. Background technique [0002] Due to factors such as the unpredictability of the arrival time of the existing bus system, citizens wait for a long time at the platform and the bus travel rate is low. Scholars at home and abroad have proposed many travel time prediction models, such as historical trend methods, non-parametric regression models, time series methods, neural networks, and Kalman filter models. However, these methods and models cannot achieve satisfactory prediction results under changing traffic conditions and arbitrary time periods. [0003] Floating vehicle traffic information collection technology is a technology that uses the vehicle's dynamic position change information to extract real-time road conditions by installing Beidou BDS, American Beidou and other dev...
