AB  - We study the traffic of two types of molecular motors using the two-species 
      asymmetric simple exclusion process (ASEP) with periodic boundary conditions and 
      with attachment and detachment of particles. We determine characteristic 
      properties such as motor densities and currents by simulations and analytical 
      calculations. For motors with different unbinding probabilities, mean-field 
      theory gives the correct bound density and total current of the motors, as shown 
      by numerical simulations. For motors differing in their stepping probabilities, 
      the particle-hole symmetry of the current-density relationship is broken and 
      mean-field theory fails drastically. The total motor current exhibits exponential 
      finite-size scaling, which we use to extrapolate the total current to the 
      thermodynamic limit. Finally, we also study the motion of a single motor in the 
      background of many nonmoving motors.
