A method and apparatus for establishing a computable road network

Abstract

The invention discloses a method and an apparatus for establishing a computable road network, wherein, the method comprises the following steps: collecting static and dynamic data of the road network;the road nodes being calibrated according to the static data of the road network, and the nodes being connected into roads according to the connection relations among the nodes, and the basic road network being constructed; constructing a connectivity road network according to the connectivity information between roads; according to the static and dynamic data of the road network, the traffic facilities in the road network being precisely calibrated by the calibration function and the computable road network being constructed. A basic road network is established according to the calibration node, then the connectivity road network is constructed and all kinds of traffic facilities are demarcated, and the computable road network is constructed, which can be calculated for different nodes and roads to obtain more accurate information of the road network, and the topological relationship of the road is used in the construction process, which is suitable for the calculation of complex road network and provides reliable analysis data for traffic operation, management and so on. As a method and a device for establishing a computable road network, the invention can be widely applied in the field of electronic map.

Description

technical field [0001] The invention relates to the field of high-precision maps, in particular to a method and device for establishing a computable road network. Background technique [0002] At present, the electronic map technology represented by AutoNavi Map and Baidu Map has been relatively mature. Electronic maps have the advantages of fast, convenient, and high positioning accuracy in terms of vehicle dynamic navigation, finding buildings, parking spaces and other physical objects. However, these applications are mainly for drivers, and for traffic managers, only the electronic map can only see the spatial position, road driving direction, number of road lanes or a small number of special lanes (such as bus lanes, non-motorized lanes) ), as well as signal lights and other information, but it is impossible to determine the relationship between lanes (such as dashed and solid lines), the refined lane direction (such as the left-turn waiting area at the intersection), th...
