Introduction

SUMO allows modelling access restrictions via a predefined set of so-called vehicle classes. Each vehicle has a vehicle class and each simulation lane allows a set of vehicle classes. Vehicles may only drive on lanes that allows it's vehicle class.

This is useful for describing multi-modal traffic scenarios by distinguishing between passenger cars, bicycles, tram and pedestrians.

Vehicle definition

The vehicle class of a vehicle is defined by first defining a vehicle type with the appropriate vehicle class and thenassigning that type to the vehicle. An example is given below:

<routes>
   <vType id="myType" vClass="bus"/>

   <vehicle id="veh0" type="myType" depart="0">
      <route edges="a b c"/>
   </vehicle>
</routes>

If no such definition is given, the vehicle class defaults to passenger (normal passenger cars). By setting the vClass attribute, a set of default type parameters is automatically assigned to better correspond to a typical vehicle of that class.

Network definition

In a .net.xml file, each lane defines a set of permitted vehicle classes. This definition is either

For visualizing access permissions, either SUMO-GUI or NETEDIT may be used.

Special cases

The vehicle class ignoring may drive on any edge.

The vehicle class pedestrian should not be assigned to a vehicle. Instead, pedestrians should be modeled as walking persons. During network building, no direct connections between pedestrian-only lanes are built. Instead options for building pedestrian intersections should be used.
