The current mobility conditions in Colombia give place to questions about the suitability of the traffic control strategies applied on the Colombian urban networks. Therefore, a review of the control strategies and simulation platforms used in Colombia and around the world is shown. This is done to characterize the level of development of the country, in terms of research and implementation of such control strategies and, furthermore, to formulate proposals oriented towards the improvement of the Colombian urban mobility.

In this paper we describe the implementation of a single-route city-bus timetabling LP model proposed by Riaño [15]. The aforementioned model considers stochastic issues like travel time and demand. A simulation model is also described, which was used to compare results from this model with others proposed in the literature. Preliminar results are promising. [ABSTRACT FROM AUTHOR]
