Traditional public policy gives solutions in a general way and don’t take into account proper dynamics of the different zones. The paper proposes a methodology for local order screening of alternatives for loading and unloading goods in Bogota.
Bogota’s government municipality has developed measures to mitigate freight transport impact on traffic congestion, among them are restrictions in the movement and parking on some places and times. Attempts to solve this problem, are evident in: Master supply plan, where the strategy of food distribution is defined; Master mobility plan, which is a compendium of measures for traffic regulation; Logistics city plan, characterizes the impact of the distribution of goods on mobility. However the congestion problem continues.
The above policies, gives solutions in a general way, and do not take into account the socioeconomics dynamics of the different zones that exist in Bogota. The following paper proposes a methodology for screening alternatives of loading and unloading local goods. To this end a review about the evolution of freight public policy that have tried to give answers to congestion and pollution problems in the last fourteen years is presented. Additionally, a ranking of the proposed solutions and its possible impacts in different sensitive economic sector is presented.
Methodologies for evaluating public policy do not necessarily consider own freight transport characteristics in supply and distribution processes more over, they are applied over a set of previously defined alternatives. This definition can exclude solutions that are appropiate in a specific context. A methodology for preselecting measures can include other measures that are not evident for the decision maker on public policy. Additionally, taking into account the change in the socioeconomic dynamics between zones reduces the subjectivity of the overall process of definition of alternatives.
As a case study methodology in eleven areas of Bogota was applied, based on data collected through surveys and direct observation of the loading and unloading operations in areas identified as critical by the local transit authority. As result the study shows that public policies on urban logistics can not only establish general measures, but must include a set of particular measures that consider local factors such as size and type of companies located in the area, the type and the amount of cargo handled, as well as the supply chain it belongs. Since Bogota is a city highly sectorized solutions can change dramatically from one area to another.
