Hi, the document you linked to lists all the default travel modes provided by Esri. The Fire Truck mode isn't a default travel mode provided by Esri, if you see it in your organization, it is possible that the administrator of your ArcGIS Online organization creates that travel mode. You might want to check with the administrator and see what settings they turn on for the Fire Truck mode.
When the administrator configures the travel mode, he is probably turning on some restrictions to represent what roads a fire truck has access to. Here is the documentation for all the restrictions that can be turned on/ off on each travel mode.
A few restrictions might have been configured by the admin include:
- Driving an Emergency Vehicle—Does not include roads where emergency vehicles are prohibited. Using this restriction also ensures that the results honor one-way streets.
- Height Restriction—Does not include roads where the vehicle height exceeds the maximum allowed height for the road. The vehicle height can be specified using the Vehicle Height (meters) restriction parameter.
- Length Restriction—Does not include roads where the vehicle length exceeds the maximum allowed length for the road. The vehicle length can be specified using the Vehicle Length (meters) restriction parameter.
- Weight Restriction—Does not include roads where the vehicle weight exceeds the maximum allowed weight for the road. The vehicle weight can be specified using the Vehicle Weight (kilograms) restriction parameter.
- Width Restriction—Does not include roads where the vehicle width exceeds the maximum allowed width for the road. The vehicle width can be specified using the Vehicle Width (meters) restriction parameter.
Hope this helps.
