Assignment of point level address geocodes to street networks include the steps of entering address data and collecting candidate point data records and segment data record matches for the entered address. Each point data record includes address elements and also includes a geocode. Each segment data record includes a centerline between segment record data points. A determination is made if there is at least one point data record match for the input address. The best point record match for the input address is selected when at least one point data record match is made. The address elements from the point record are compared to any collected segment data records. A determination is made of the best segment record match to the selected best point record and the best segment record match is selected. The selected best segment record is employed and the bearing and distance from the selected best point record is calculated to a point on the centerline of the selected best segment record to determine a geocode for the centerline point.

The invention provides a method for preparing a traffic source emission inventory with high spatio-temporal resolution. The method includes: Step 1: Obtaining street road network composition information of the target city; Step 2: Obtaining traffic flow information of each road section of the street; Step 3: According to the traffic flow information of each road section of the street, calculating the traffic flow rate of various vehicles per hour Traffic flow of each road section; Step 4: According to the traffic flow of various vehicles in each road section per hour, calculate the pollutant emissions of vehicles with different service life. The invention considers the three factors of road network structure, motor vehicle type and traffic change status, obtains the hourly driving change of motor vehicles, compiles the motor vehicle pollutant discharge list in the area, and can prepare hourly traffic source pollution on the street scale emissions inventory.

The invention discloses an urban street space vitality simulation method and system, computer equipment and a storage medium. The method comprises the following steps: acquiring a map image in a research range; creating street line elements, drawing a street network on the map image, and generating street road segment line elements; generating facility point elements, and inputting distance screening facility point elements influencing street vitality; generating a neighbor table of facilities and streets; generating street intersection elements; constructing a facility-street intersection ODtable to obtain street network distances between all facilities and two intersections of all streets; calculating the average vitality of all streets to obtain a street vitality table; generating a current street vitality grid and a planned street vitality grid; and generating a comparison grid of planning and current street vitality. The urban current street vitality can be simulated, the plannedstreet vitality can be simulated according to planning requirements, and the planning effect can be predicted by comparing the current street vitality with the planned street vitality.

The invention relates to a method and a device for providing an electronic horizon for a driver assistance system of a vehicle, wherein the current position of the motor vehicle is determined and the electronic horizon is created by means of a heuristic on the basis of map information of the street network in the surrounding areas of the current position of the motor vehicle. In so doing, a probability consideration of the heuristic is carried out and an accuracy probability of the heuristic is determined.

The invention discloses a network-based street lamp control method, device and system. The method includes: the group station collects the corresponding relationship between the number of each street lamp and the actual position of each street lamp; the group station sends the corresponding relationship to the control terminal; the group station receives the control command returned by the control terminal, and the control command is for the corresponding The command generated by the street lamp corresponding to any number in the relationship; the group station converts the control command into a dimming signal and sends it to the street lamp at the actual location corresponding to any number. The invention solves the problem that the street lamp control method in the prior art can only adjust the switch and brightness of the whole street lamp, but cannot control a certain designated area or a designated street lamp, resulting in low street lamp control efficiency.

A method and system for generating fixed transit routes is provided. A first set of street network segments within a first threshold distance from a starting point is identified for a pattern inputted by a user. A proxy first point along each of the street network segments in the first set is also identified. A second set of street network segments within a second threshold distance from an ending point is identified for the pattern inputted by the user. A proxy second point along each of the street network segments in the second set is also identified. A best path for the pattern is determined including any one of the proxy first points along the street network segments in the first set and any one of the proxy second points along the street network segments in the second set.

The invention discloses a streetlight network control method, comprising the steps of: immediately turning on a streetlight when the streetlight acquires a vehicle passing condition and measures a measured vehicle speed signal through a signal acquisition unit; meanwhile, commanding a plurality of streetlights ahead to be turned on for several seconds according to a preset corresponding value between the vehicle speed and the number of the turned-on streetlights ahead as well as a preset corresponding value between the vehicle speed and the light-on time; and turning off the streetlight after the vehicle runs through the streetlight. Meanwhile, by monitoring ambient brightness, vehicle traffic flow and ambient humidity and regulating the illumination brightness of the streetlight, invalid illumination is avoided. The control method disclosed by the invention has the advantages that the proper illumination brightness can be provided by the streetlights according to specific environments in bustling downtown areas and solitude road sections, and the electricity can be saved by 30%; and the method is completely adopted in the solitude road sections, the electricity can be saved by 70% in average and 90% at most. If an LED light source is adopted, the service life of the streetlight can be prolonged by 5 times.
