Abstract
An apparatus and a method for providing traffic information are provided. The apparatus includes a traffic data database (DB) that stores traffic data and a processor connected to the traffic data DB. The processor generates a prediction model to predict a traffic flow and determines an appropriate data input range for a target time point in the future using the prediction model. Additionally, the processor extracts past traffic data from the traffic data DB based on the determined appropriate data input range, predicts a traffic flow at the target time point based on the extracted past traffic data and provides the predicted traffic flow as traffic information.
Claims11
An apparatus for providing traffic information, comprising:
- a non-transitory storage medium configured to store a prediction model for predicting a traffic flow;
- a traffic data database (DB) configured to store traffic data;
- and
- a processor connected to the traffic data DB,
- wherein the processor is configured to:
- receive a target time point in the future from an input device;
- determine a data input range for the target time point in the future using the prediction model by:
- receiving past travel speed data for a plurality of prospective data input ranges;
- predicting a travel speed at the target time point for each of the plurality of prospective data input ranges using the prediction model;
- calculating, for each prospective data input range, a relative error amount between each predicted travel speed and an actual measured travel speed;
- and
- determining the data input range to be the prospective data input range of the plurality of prospective data input ranges having the smallest relative error amount;
- extract past traffic data from the traffic data DB based on the determined data input range;
- predict the traffic flow at the target time point based on the extracted past traffic data;
- and
- output the traffic flow to an output device as the traffic information.
A method for providing traffic information, comprising:
- receiving, by a processor, a target time point in the future from an input device;
- determining, by the processor, a data input range for the target time point in the future using a prediction model for predicting a traffic flow stored in a non-transitory storage medium by:
- receiving past travel speed data for a plurality of prospective data input ranges;
- predicting a travel speed at the target time point for each of the plurality of prospective data input ranges using the prediction model;
- calculating, for each prospective data input range, a relative error amount between each predicted travel speed and an actual measured travel speed;
- and
- determining the data input range to be the prospective data input data input range of the plurality of prospective data input ranges having the smallest relative error amount;
- extracting, by the processor, past traffic data from a traffic data database (DB) based on the determined data input range;
- predicting, by the processor, the traffic flow at the target time point based on the extracted past traffic data;
- and
- outputting, by the processor, the traffic flow to an output device as the traffic information.
