Appendix 2[50]

ALGORITHM FOR CALCULATING EXCESSIVE SPEED
(Annexed to Circular No. 09/2015/TT-BGTVT dated April 15, 2015, issued by the Minister of Transport)

I. Abbreviated Terms:

- N: Is the sequence number of the report from the vehicle tracking device.

- V_[N]: Instantaneous speed (km/h).

- V_limit[N]: Maximum allowable speed (km/h).

- V_tb[N]: Average speed (km/h).

- Vss[N]: Speed for comparison with Vlimit[N] to determine violation (km/h).

- V_vipham[N]: Excessive speed (km/h).

- d.1. Amount of taxable income in Vietnam:_tb[N]: Time interval between report N and N-1 (seconds).

- D_tb[N]: Distance interval between report N and N-1 (kilometers).

II. Calculation Flowchart

III. Description of Calculation Flowchart

After filtering out invalid reports as described in Appendix VI of this Circular, the calculation of excessive speed shall be performed.

a) Calculate the time interval compared to the previous report (Ttb[N]), depending on this time interval, the average speed and distance will be calculated as follows:

- T_tb[N] > 60 seconds: Do not calculate excessive speed and will record data transmission violations.

- 10 seconds < T_tb[N] <= 60 seconds: Calculate distance based on the coordinates of two consecutive reports. Calculate speed = min (((D_tb[N] / T_tb[N]) *3600); (D_tb[N] / T_tb[N]) *3600));

- T_tb[N] <= 10 seconds: Calculate distance = V_tb[N] * T_tb[N]. Calculate speed: V_tb[N] = (V_[N]+ V_[N-1])/2.

b) Calculate comparative speed (V_ss[N]): V_ss[N] = V_tb[N] -3

The speed error currently applied in the system for all devices is -3 km/h.

c) Calculate excessive speed

- Start calculating speed violation at the moment V_ss[N] > V_limit[N] until the end of the violation V_ss[N] <= V_limit[N] (measured in seconds). If V_ss[N] > V_limit[N] is maintained continuously for 20 seconds or more, it will be recorded as a speeding violation.

- V (VND/year): is the total investment capital allocated annually for the usable area of social housing for rent, ensuring the preservation of capital, calculated according to the following formula:_vipham[N] = V_ss[N] – V_limit[N]

Use the highest excessive speed and the corresponding maximum allowable speed to determine the level of violation according to the range (under 5 km/h, from 5 km/h to under 10 km/h, from 10 km/h to 20 km/h, over 20 km/h to 35 km/h, over 35 km/h).

Note:

- The speed displayed on the online tracking map and in the detailed journey statistics table is the instantaneous speed (V

) (information taken from each transmitted report)._[N]> 200 km/h. → discard the report. If the subsequent report after V

- V (VND/year): is the total investment capital allocated annually for the usable area of social housing for rent, ensuring the preservation of capital, calculated according to the following formula:_[N] > 200 km/h compared to the previous report V_[N] > 200 km/h, time >60 seconds then stop calculating speed violation. If the time <60 seconds then still calculate Vss._[N] = 0 km/h → still calculate V

- V (VND/year): is the total investment capital allocated annually for the usable area of social housing for rent, ensuring the preservation of capital, calculated according to the following formula:_[N] ss_{as usual.} Appendix 3[51]

Appendix 3[51]

FILTERING AND NOISE REMOVAL OF NOTICES PRIOR TO CALCULATION
(Annexed to Circular No. 09/2015/TT-BGTVT dated April 15, 2015, issued by the Minister of Transport)

The servers of transportation business units or service providers and the servers of the Vietnam Highway Administration will perform noise filtering and removal on received notices before incorporating them into calculations, including:

1. Notices with invalid time stamps

o Time sent into the future

o The time stamp of a subsequent notice is earlier than that of a previous notice

2. Notices with invalid coordinates

o Longitude or latitude = 0

o Sudden jumps in longitude and latitude over a short period of time (distance/time ≥ 200 km/h)

o Coordinates outside the territory of Vietnam, not located on land

3. Notices with invalid speed

o Instantaneous speed reported ≥ 200 km/h

o Consistent fixed speed across consecutive notices

o Speed < 0 km/h

In cases where units use engine on/off status for vehicle movement calculation, attention should be given to situations where the vehicle is off but still reports speed > 3 km/h.

4. Exception handling cases

- Other exceptions arising during data processing will be continuously updated. The Vietnam Highway Administration provides specific handling solutions for these cases on its website and notifies units to implement consistent handling methods.

- Handling solutions for certain exception cases

METHOD FOR CALCULATING WITHOUT DATA TRANSMISSION
(Annexed to Circular No. 09/2015/TT-BGTVT dated April 15, 2015, issued by the Minister of Transport)

1. Regarding data transmission frequency:

To ensure accuracy and ease of calculation, it is recommended that units transmit data at a frequency ≤ 10s/notice

2. Data transmission in the event of a lost signal:

a) As soon as the device regains signal, the data transmission unit shall transmit current and past data from the time of signal loss to the time of signal recovery as stipulated

Additional data transmission will be conducted through a separate channel, monthly supplementary data must be completed before the 4th of the following month. After receiving data at the times of previous signal losses, the system will recalculate all parameters

b) Transmit current data to serve real-time display of vehicle position on the monitoring screen

c) Data from the time of signal loss to the present time is transmitted in chronological order to serve the prescribed calculation

3. Detailed calculation of each non-data transmission violation

a) A non-data transmission violation is determined when the vehicle moves to a new position compared to the recorded position at the start of data cessation and there is no data during the movement between two positions. Specifically, Ttb[N] > 120s and Dtb[N] > 500m

b) Or based on toll station data collected to compare with existing system data

4. Vehicles not transmitting data on a daily basis

Vehicles not transmitting data on a daily basis are considered to have transmitted zero notices to the system N=0, or have transmitted data but the information in the transmitted notices is unusable (faulty notices)

{double P1X = VIDO1 * (Math.PI / 180);

double P1Y = KINHDO1 * (Math.PI / 180);

double P2X = VIDO2 * (Math.PI / 180);

double P2Y = KINHDO2 * (Math.PI / 180);

double Kc = 0;

double Temp = 0; Kc = P2X - P1X;

Temp = Math.Cos(Kc);

Temp = Temp * Math.Cos(P2Y);

Temp = Temp * Math.Cos(P1Y);

Kc = Math.Sin(P1Y);

Kc = Kc * Math.Sin(P2Y); Temp = Temp + Kc;

Kc = Math.Acos(Temp); Kc = Kc * 6376;}

Note:

Distance calculation is only performed when instantaneous speed > 0 km/h.
