TRAVEL TIME ESTIMATION METHOD FOR ROAD BASED ON BUILT-UP ENVIRONMENT AND LOW-FREQUENCY FLOATING CAR DATA

WIPO Patent Application WO/2018/103449

A1

The present invention relates to the technical field of urban transportation management and transportation system evaluation. Provided is a travel time estimation method for a road based on a built-up environment and low-frequency floating car data. The method adopts a built-up environment as an explanatory variable for an amount of time spent driving on a road, and the ability of the built-up environment to explain the amount of time spent driving on the road is proven by means of an example calculation, thereby providing a method estimating a travel time distribution coefficient for a road or roads according to a distribution of cars on the road. After being used to establish a historical travel time database, the travel time distribution coefficient replaces a distance to serve as a driving time distribution coefficient for the road. The method explains an increment in an amount of time spent driving on a road as the result of a built-up environment, and can reflect different driving speeds on different parts of the road, thereby improving precision of estimated travel time for a road.
