| Summary: | In recent years the demand of the urban mobility sector has become of a particular interest. The high dependency on mobility and the excessive use of cars in urban areas are matters of concern because the transportation systems are lead to unsustainable scenarios. This circumstance makes long-term planning highly relevant in trying to reverse this trend. There should be an integrating project that is based on the development of strategies according to indicators that show whether urban mobility is really intended to be sustainable, and at the same time its positive effects are maximized and the negative ones are mitigated. This paper proposes a new method for calculating such indicators and sustainability relationships for long-term decision-making, in order to analyze urban mobility in Tuxtla Gutiérrez and achieve sustainable urban mobility environments. A methodical analysis is made of the flows that intervene in the dynamic functioning of urban mobility and its different alternatives, by evaluating all the energy used in this process (all this energy is called eMergy), of the different components for quantify them in identical units. With this evaluation we attempt to know the emergetic flows and deposits of the different mobility alternatives. The sustainability indices and other correlations that indicate the degree of dependence on urban mobility were also calculated, the results are shown graphically. Finally, an analysis of the environmental burden is presented, showing how environmentally friendly the current urban mobility system can be. It was found that the bicycle is the mobility alternative that consumes less eMergy and that the one that consumes the most eMergy is the Conejobús. Regarding the eMergy index per kilometer per person per type of unit, it is shown that the Conejobús is the most efficient modality above collective transport and bicycles. With respect to total eMergy index of mobility by type of alternatives, the most efficient was the Conejobús followed by collective transport and bicycles. |
