If you are interested in running Autoware with maps of your own environment, please visit the [How to Create Vector Map](https://autowarefoundation.github.io/autoware-documentation/main/how-to-guides/integrating-autoware/creating-maps/#creating-maps) section for guidance.

+## Want to Try Autoware with Higher Speed?
+
+The original Autoware is designed to operate at a wide speed range. But for safety reasons, the default maximum velocity has been limited to 15 km/h. In that case, even you drag the slider to a higher speed in rviz panel, the system will not allow it.
+
+If you want to run Autoware at a higher speed, you can modify the `max_vel` parameter in the config file [common.param.yaml](https://github.com/autowarefoundation/autoware_launch/blob/main/autoware_launch/config/planning/scenario_planning/common/common.param.yaml) located in the `config` directory of your autoware_launch.

+
+For example, to set the maximum velocity to 72 km/h, you would change the value to `20.0` (since 72 km/h is equivalent to 20 m/s).
