Multiple first average vehicle speeds V1) and second information of the second lane L2 (namely the above multiple second position information and multiple second average vehicle speeds V2 passing through each second position within a predetermined time).

As mentioned above, after the communication module 11 receives the first information of the first lane L1 and the second information of the second lane L2, the processing module 12 of the remote server 10 can obtain the distance between each first position according to each first position information. A plurality of first distances D1 (such as 500 meters, 1 kilometer or 2 kilometers) and a plurality of second distances D2 (such as 500 meters, 1 kilometer or 2 kilometers) between each second position obtained according to each second position information . Specifically, as shown in FIG. 2 , since the processing module 12 can obtain the coordinates of the first vehicle detector 31 at each first position, the distance between the first vehicle detectors 31 can be calculated, for example For example, if two adjacent first vehicle detectors 31 are respectively located at 18.3 kilometers and 19.3 kilometers on an expressway, the processing module 12 can calculate the first distance between the two first positions. The distance D1 is 1 kilometer (19.3 kilometers-18.3 kilometers). Similarly, the processing module 12 can also obtain a plurality of second distances D2 between the second positions according to the information of the second positions, and details will not be repeated here.

The second distance D2 between each second vehicle detector 32 (that is, each second position) of the second lane L2 is also 1 kilometer, and a plurality of second average values of each second vehicle detector 32 are passed within 1 minute. The vehicle speed V2 is 78km/h, 71km/h, 65km/h, 68km/h respectively. The processing module 12 of the remote server 10 can respectively calculate the first estimated driving time and the second estimated driving time according to the following formula:

Wherein C1 is the first expected driving time of driving the first lane L1, n is the number of the first vehicle detectors 31, D is the first distance D1 between the first positions, and V is the first distance between each first position within 1 minute. The first average vehicle speed V1 of the location. In this way, the calculation formula of the first estimated driving time C1 can be: [3600 (seconds) × 1 (km) ÷ 63 (km/h)] + [3600 (seconds) × 1 (km) ÷ 72 (km/h )]+[3600(second)×1(km)÷68(km/h)]≒160.08 seconds.

Wherein C ₂ is the second expected driving time of driving the second lane L2, n is the number of the second vehicle detectors 32, D is the second distance D2 between the second positions, and V is the second distance D2 between the second positions, and V is the second distance between each second position in 1 minute. The second average vehicle speed V2 at the second position. In this way, the calculation formula of the second estimated travel time C2 can be: [3600 (seconds) × 1 (km) ÷ 78 (km/h)] + [3600 (seconds) × 1 (km) ÷ 71 (km/h )]+[3600(second)×1(km)÷65(km/h)]≒152.23 seconds.

The second distance D2 between each second vehicle detector 32 (that is, each second position) of the second lane L2 is also 1 kilometer, and a plurality of second average values of each second vehicle detector 32 are passed within 1 minute. The vehicle speeds V2 are 78km/h, 71km/h, 65km/h, and 68km/h respectively, and the passing numbers of the second vehicles measured by the second vehicle detectors 32 are 30, 33, 26, and 27 respectively. The processing module 12 can respectively calculate the total number of first vehicles passing through the first lane L1 and the total number of second vehicles passing through the second lane L2 according to the following formula:

Wherein N ₁ is the total number of the first vehicle passing, n is the number of the first vehicle detector 31, X is the number of the first vehicle passing, m is the number of vehicle detectors repeatedly detecting the same vehicle, and R is the number of vehicle detectors in a predetermined time Traveling distance, D is the first distance D1 between the first positions, whereby the calculation formula of the total number N1 of the _first vehicle passing can be: 106 (sets) - {[24 (sets) × ((63 (km /h)÷60(min))-1(km))÷(63(km/h)÷60(min))]+[28(unit)×((72(km/h)÷60(min) )-1(km))÷(72(km/h)÷60(min))]+[26(unit)×((68(km/h)÷60(min))-1(km))÷ (68(km/h)÷60(minutes))]+[28(units)×((75(km/h)÷60(minutes))-1(km))÷(75(km/h)÷ 60(minutes))]}≒92(units)

Wherein N2 is the total number of the second vehicle passing, n is the number of the second vehicle detector 32, X is the number of the second vehicle passing, m is the number of vehicle detectors repeatedly detecting the same vehicle, and R is the running time in a predetermined time Distance, D is the second distance D2 between the second positions, whereby the calculation formula of the total number N2 of the second vehicle passing can be: 116 (set) - {[30 (set) × ((78 (km/h )÷60(min))-1(km))÷(78(km/h)÷60(min))]+[33(unit)×((71(km/h)÷60(min))- 1(km))÷(71(km/h)÷60(min))]+[26(unit)×((65(km/h)÷60(min))-1(km/h))÷(65 (km/h)÷60(min))]+[27(unit)×((68(km/h)÷60(min))-1(km))÷(68(km/h)÷60( points))]}≒100 (units).
