  We propose a generalized market equilibrium model using assignment game
criteria for evaluating transportation systems that consist of both operators'
and users' decisions. The model finds stable pricing, in terms of generalized
costs, and matches between user populations in a network to set of routes with
line capacities. The proposed model gives a set of stable outcomes instead of
single point pricing that allows operators to design ticket pricing,
routes/schedules that impact access/egress, shared policies that impact
wait/transfer costs, etc., based on a desired mechanism or policy. The set of
stable outcomes is proven to be convex from which assignment-dependent unique
user-optimal and operator-optimal outcomes can be obtained. Different user
groups can benefit from using this model in a prescriptive manner or within a
sequential design process. We look at several different examples to test our
model: small examples of fixed transit routes and a case study using a small
subset of taxi data in NYC. The case study illustrates how one can use the
model to evaluate a policy that can require passengers to walk up to 1 block
away to meet with a shared taxi without turning away passengers.
