One Mexico, two presidents

After the electoral fraud last July in Mexico, the right wing candidate Felipe Calderón is due to take possession of the presidency on Decembe 1st. However, things are still uncertain as left wing candidate Andrés Manuel López Obrador (who was the real winner of the elections), was declared "legitimate president" by millions at the National Democratic Convention, and should take possession on November 20th, the anniversary of the Mexican Revolution. If the institutions betray the people, the people can deny those institutions...
In general, the situation is not violent. However, the conflict in the state of Oaxaca is reaching new heights. The APPO movement, formed mainly by teachers and peasants, has the capital of the state "under siege" for several months now. In practice, the governor hasn't been in office since then. The sentate studied the disappearance of powers in Oaxaca, but even when they admit that the state is not governable, they didn't declared it. People from the APPO have been murdered by supporters of the governor Ulises Ruiz, who, if he had things his way, would send the army to violently repress the movement. Now the APPO declared a "pacific insurrection", and told that if the governor does not leave his position, Calderón will not be able to take possession.
Combined with the conflicts in neighbouring states Chiapas, Tabasco, and Guerrero, things are quite uncertain... Let's see what happens...

New paper: Self-organizing traffic lights: A realistic simulation



Cools, S.B., C. Gershenson, and B. D'Hooghe (2006). Self-organizing traffic lights: A realistic simulation. Submitted.

Abstract:We have previously shown in an abstract simulation (Gershenson, 2005) that self-organizing traffic lights can improve greatly traffic flow for any density. In this paper, we extend these results to a realistic setting, implementing self-organizing traffic lights in an advanced traffic simulator using real data from a Brussels avenue. On average, for different traffic densities, travel waiting times are reduced by 50% compared to the current green wave method.
