In this study, an interval-parameter programming method has been used for urban vehicle emissions management under uncertainty. The model improves upon the existing optimization methods with advantages in uncertainty reflection, system costs and limitation of emission. Moreover, the model is applied to a case study of urban vehicle emissions management in a virtual city. The results indicate that the interval linear traffic planning model can effectively reduce the vehicles emission and provide strategies for authorities to deal with problems of transportation system.

The aim of this work is to show the socio-economic impact in the Cundinamarca-Boyacá plateau produced by the construction and promotion of an alternative to relieve the freight transportation system in the region, and how it echoes in the manufacturing levels of the ship industry. For this reason, it is evaluated the option of establishing a logistics area in the town of Puerto Salgar (Cundinamarca) where may confluence an intermodal transportation system which emphasizes the Magdalena River as the main way for the country’s development and Puerto Salgar as the main axis for the economic growth of the plateau. The Discrete Event Simulation (DES) methodology was used for this work, using information given by previous studies by the Ministerio de Transporte, the Dirección Nacional de Planeación and the Instituto Nacional de Vías; setting a conceptual model which determines and limit the study, and implementing a Rockwell Arena simulation.
