Data collected from a loop detector station for 24 hours are included in the attached file HW1_data1.traffic. Please answer the following questions.
The data was provided by Minnesota Department of Transportation and was coded using binary unified transportation sensor data format (UTSDF). The format of UTSDF is explained in the attached file HW1_UTSDF.pdf. Reformat the files in the Excel format as shown in Figure 1 (Hint 1: In MATLAB, use dir command to merge the files based on their sequence for flow and occupancy; Hint 2: In MATLAB, use fread commend to open and read the binary file by designated bytes).
a. Error checking: check the detector data provided;
b. Calculatethespeedfromtheflowandoccupancydata.Stateyourassumptions
clearly;
c. Analyze the data to determine changes in traffic states if any and their
characteristics;
d. The detector is located approximately in the middle of a 1-mile freeway
segment. Calculate the delay to the traffic stream (Hint: define delay first and then calculate the delay in veh-hrs).
