Below is a summary of perspective tasks of type 2 on optimizing transportation in city, which are a further development of the above tasks of type 1. For these perspective tasks do not yet exist means of their solving.

     These tasks are characterized by the following new features:

• the presence of several different-type transport vehicles (TVs) rather than one TV as in the solvable tasks of type 1;
• specifying for each TV the signs of accessibility of serving target points (TPs);
• the possibility of minimizing the total time of serving all TPs by this group of TVs.
