This program generates inputs for the 505.mcf SPEC2017 benchmark. It simulates a city and uses a common bus-route designing technique to radiate bus routes from a central location. The program uses a circadian cycle to generate more routes at prime times in the day accounting for increased number or commuters. To create a city map, it starts with a perfect fully connected grid. Then it eliminates intersections from the grid and all the associated edges connecting the eliminated point with other points to simulate parks and larger squares in a city. It then create roads that travel diagonally across the city. Such connections are similar to major diagonal avenues such as the ones found in Washinton DC.There are also considerations to reduce overlapping routes such as adding increased cost to the A* algorithm when calculating the path for bus routes.
The program is designed to run after build without any changes to the configuration. There is also a template configuration file provides. This template can be regenerated using the -g flag. The default file (default.cfg) contains an explanation of all tunable parameters.
