Title: Jia Rao: Innovator in Data Indexing and Traffic Prediction

Introduction

Jia Rao is a prominent inventor based in Beijing, China. He has made significant contributions to the fields of data indexing and traffic prediction. With a total of 2 patents, his work focuses on improving data management and enhancing traffic forecasting accuracy.

Latest Patents

Jia Rao's latest patents include a data indexing system, data indexing method, and data querying method. This innovative data indexing system is designed to split a predetermined time range into multiple time intervals. It features a first index creating unit that generates a first-level index for data within the current time interval, which includes both a time interval index and a subspace index. Additionally, a second index creating unit is responsible for creating a second-level index in a subsequent time interval, offering finer granularity than the first-level index. This system significantly reduces the cost of index maintenance during frequent updates and enhances query performance by minimizing invalid scans.

Another notable patent is the method and system for traffic prediction based on spatial-temporal relations. This invention includes a section spatial influence determining section that assesses the spatial influences on each section to be predicted. It establishes a traffic prediction model using these influences alongside historical traffic data. The system predicts future traffic conditions by utilizing real-time data and the established models, thereby improving the accuracy of traffic predictions.
