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.

A survey was conducted for analyzing "pico and placa" measure in Medellin city, using Stated Preference Methods which involve a range of techniques dealing with creation of individual responses about preferences in several transportation means. Laureles neighborhood was the area chosen for conducting the DPM study, since it is one of the areas having the biggest amount of vehicles in the city, so it makes a big contribution to general traffic congestion. It was found that private drivers are not in agreement with "pico y placa" measure, but chaotic traffic in the city is improved with its application. They would rather prefer to share a vehicle with other person (48%) since a private vehicle is a much more comfortable transportation mean. Then they would choose buses (37%), since it is a good service, but lack of safety is a negative factor. 9% would travel to their place of destination in a taxi, since it is a comfortable and safe means; and remaining 6% would use either taxi or metro, though it involves a mandatory transfer when destination is a long distance away.
