Data Processing - 2023.2 English

Place the calculated required data set in csr_data/ directory.

• Indices and weights information:

  • Put indices and weights in the same file. The first row shows the number of links (edges).

  • Each column of data represents cost, flow_free_time, volume, and capacity, respectively.

    76
    1 6.000816237 6 4494.657646 25900.20064
    2 4.00869075 4 8119.079948 23403.47319
    ...
    ...
    

• Nodes information

  • Each column of data respresents longitude and latitude, respectively.

    -96.77041974 43.61282792
    -96.71125063 43.60581298
    ...
    ...
    

• Offsets data

  • The first row shows the number of nodes (vertices) and the name of the city.

    24 Cityname
    0
    2
    ...
    ...
    

Follow these steps to run the coo2csr program to calculate the offset:

1. Put the COO format rows and columns information as file city.mtx in coo_data/.

   • The first row shows the number of nodes, links, and city name.

   • Each column of data contains rows and indices.

     24 76 Cityname
     0 1
     0 2
     ...
     

2. Run the mkoffset.sh script to generate the offset.

   The first argument is the file name of city.mtx in coo_data/ and the second argument is the offset name that you want to generate in the csr_data/ folder.

     $ ./mkoffset.sh city.mtx offset_city.mtx
   

   The following information is displayed. You can find the offset.mtx in the csr_data/ folder.
