Using default scenarios

3D environment maps curated and maintained by MORAI may be distributed with their own set of default scenarios.

These default scenarios are either specially designed scenarios for often-used maneuvers that are difficult to set up for first-time users, or quick test scenarios so that users do not need to design their own scenarios every time they load into a map.

Navigate to Edit >> Scenario >> Load Scenario from the main menu bar - this is the exact same screen for loading any user-created scenario .json files. Once the save management UI appears, select the Default tab in the window. Any sample or default scenario .json files associated with the map should be listed.

Below is an example screenshot of the default scenario loaded into the K-City map. NPC vehicles are already placed and ready to move.

List of available default scenarios

This list adheres to the following convention.

  • Map Name

    • Scenario File Name: Description of the scenario

  • R_KR_PG_K-City

    • TrafficFlow.json: The default scenario.

  • R_KR_PG_KATRI

    • TrafficFlow.json: The default scenario.

  • V_RHT_HighwayJunction_1

    • TrafficFlow.json: The default scenario

    • HWJC1_Sample01.json: The ego-vehicle is positioned to cut into a congested lane of traffic along the highway.

    • HWJC1_Sample02.json: The ego-vehicle is traveling in the rightmost lane approaching an on-ramp with incoming traffic. The ego must decide whether to yield or take alternate actions.

    • HWJC1_Sample03.json: The ego-vehicle is traveling within regular traffic flow on a highway, intending to take the next off-ramp to exit the highway.
