Systems and methods for determining traffic information of a region

A method implemented on a computing device having at least one processor, at least one storage medium, and a communication platform connected to a network, the method comprising:

• determining a first region and a second region, the first region being within the second region;
• obtaining a set of links associated with the first region and the second region, the set of links including a plurality of first links inside the first region, a plurality of second links cross a first boundary of the first region, a plurality of third links inside the second region other than the first region, and a plurality of fourth links cross a second boundary of the second region;
• obtaining a plurality of driving routes of a plurality of vehicles in the first region and the second region in a predetermined time period;
• selecting one or more driving routes that traverse the first boundary and the second boundary based on the set of links associated with the first region and the second region;
• and
• determining traffic information of the first region based on information related to the one or more selected driving routes, the traffic information including at least one of first traffic information indicating traffic flowing into the first region from the second region or second traffic information indicating traffic flowing out of the first region to the second region, wherein the determining the first traffic information includes:
• for each of the one or more selected driving routes that traverse the first boundary and the second boundary,
• determining a first link cross the first boundary;
• determining a second link cross the second boundary;
• determining a first location that the second link intersects with the second boundary;
• determining a second location that the first link intersects with the first boundary;
• and
• determining a first average speed of vehicles traveling from the first location to the second location with respect to each of a plurality of target links forming the second boundary of the second region;
• for each of the plurality of target links,
• determining a first count of vehicles entering the first region from each of the plurality of target links;
• and
• determining a first ratio associated with each of the plurality of target links based on the first count of vehicles and a total count of vehicles entering the first region from the plurality of target links;
• and
• determining the first traffic information based on at least one of the first average speeds, the first counts of vehicles, or the first ratios.

A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, directs the at least one processor to perform a method, the method comprising:

• determining a first region and a second region, the first region being within the second region;
• obtaining a set of links associated with the first region and the second region, the set of links including a plurality of first links inside the first region, a plurality of second links cross a first boundary of the first region, a plurality of third links inside the second region other than the first region, and a plurality of fourth links cross a second boundary of the second region;
• obtaining a plurality of driving routes of a plurality of vehicles in the first region and the second region in a predetermined time period;
• selecting one or more driving routes that traverse the first boundary and the second boundary based on the set of links associated with the first region and the second region;
• and
• determining traffic information of the first region based on information related to the one or more selected driving routes, the traffic information including at least one of first traffic information indicating traffic flowing into the first region from the second region or second traffic information indicating traffic flowing out of the first region to the second region, wherein the determining the first traffic information includes:
• for each of the one or more selected driving routes that traverse the first boundary and the second boundary,
• determining a first link cross the first boundary;
• determining a second link cross the second boundary;
• determining a first location that the second link intersects with the second boundary;
• determining a second location that the first link intersects with the first boundary;
• and
• determining a first average speed of vehicles traveling from the first location to the second location with respect to each of a plurality of target links forming the second boundary of the second region;
• for each of the plurality of target links,
• determining a first count of vehicles entering the first region from each of the plurality of target links;
• and
• determining a first ratio associated with each of the plurality of target links based on the first count of vehicles and a total count of vehicles entering the first region from the plurality of target links;
• and
• determining the first traffic information based on at least one of the first average speeds, the first counts of vehicles, or the first ratios.
