Problems solved by technology

Looking at the existing related technologies and methods at home and abroad, most of them are qualitative research based on static data, and lack of quantitative research based on multi-source spatiotemporal data.
However, most of the existing supervision systems are composed of online declaration, qualification review and status monitoring. They are mainly static supervision systems based on identity attributes, and lack dynamic supervision systems based on driving behavior.

Abstract

The invention relates to a travel safety evaluation method and a system based on multi-source spatio-temporal data. The method of the invention comprises the following steps: data collection and pretreatment, road segment division, map matching, and multi-dimensional safety index calculation. The system of the invention comprises a multi-source spatio-temporal data analysis platform, a geographical server, a government terminal, an enterprise terminal, a driver terminal and a passenger terminal. Compared with the existing static supervisory system based on identity attributes, the invention, based on multi-source spatio-temporal data mining, multi-dimensional analysis of road safety and driver safety in each section of the road at each time, can more accurately evaluate the safety level ofcar-sharing travel, and with the help of safety index to quantify the risk of car-sharing travel, and innovates the regulatory system, which is an important embodiment of the modernization of governance system and governance capacity, can improve the efficiency of government management, achieve dynamic supervision of enterprises, regulate driver driving behavior, and assist passenger travel decision-making.

Description

technical field [0001] The present invention relates to the technical field of online taxi reservation, in particular to a safety evaluation method and system for online car-hailing travel based on multi-source spatio-temporal data. Background technique [0002] The safety evaluation and supervision of online car-hailing travel has become a hot and difficult issue that needs to be solved urgently. Looking at the existing related technologies and methods at home and abroad, most of them are qualitative research based on static data, and there is a lack of quantitative research based on multi-source spatiotemporal data. Most of the existing regulatory systems currently exist are composed of online declaration, qualification review and status monitoring. They are mainly static regulatory systems based on identity attributes, and lack dynamic regulatory systems based on driving behavior. Contents of the invention [0003] The purpose of the present invention is to provide a...
