Experimenting with different methods of traffic assignment is presented, using prototype network traffic. 21 simulations were performed, using seven methods of allocating three levels of traffic. We use the following traffic assignment methods: All-or-Nothing Assignment, Stochastic Assignment, Incremental Assignment, Capacity Restraint, User Equilibrium, Stochastic User Equilibrium and System Optimum Assignment. We use three kinds of matrixes: a dense, half and half empty. In networks that are not congested, the results show that is indifferent to use one or another traffic assignment method, as the results converge to the system optimum assignment equilibrium.

This paper presents the results of stated-preference, discrete selection experiments designed to obtain quality indicators in the urban public transport service in the town of Barrancabermeja, which was raised to two alternatives that contain the attributes : fare, walking distance from origin to fate, waiting time at bus stop, travel time in vehicle, availability of seats, driver and vehicle, generating a Multinomial Logit model, which allows the city to complete study attributes most relevant to the quality of the service are: 32.6% rate, walking distance from the origin to the whereabouts 18.0% and 14.3% travel time.

This paper shows a description about UPV and TCQSM methods, developed to determinate quality and service level in urban collective public transit by bus, in order to provide a framework which permits to make a comparison of these two (2) methods to obtain the compatibility degree among formulated scales of service level. As a result of this research, this paper presents contributions of analyzed methods to measure service quality of urban collective public transit by bus. [ABSTRACT FROM AUTHOR]
