1. A method of mobile monitoring and determining a requisite number of mobile monitoring vehicles, the method focuses on a road network of an urban area, by installing air pollution detection equipment on the mobile monitoring vehicles, to monitor air quality of the urban area, the method comprising:
1) establishing a curve model of monitoring times for the mobile monitoring vehicles, which comprises:
1.1) decomposing the road network of the urban area into road segment units (RSUs); initializing a database of RSUs, which comprises RSU numbers, RSU locations, and RSU detection records;
1.2) selecting at least 50 of the mobile monitoring vehicles equipped with a positioning system; recording the number of times that each mobile monitoring vehicle passes each RSU; a maximum number of times for each mobile monitoring vehicle passing any RSU within a counting period is 1;
1.3) continuing recording for at least one week, calculating a daily average of times for each RSU; and
1.4) creating a curve model of monitoring times for the mobile monitoring vehicles, which is a statistical distribution of monitoring times for the mobile monitoring vehicles by RSUs within 24 hours;
2) determining a covered range and a number of scheduled detections; and
3) finding out a requisite number (C0) of the mobile monitoring vehicles, corresponding to a curve model.
