Description

ROTATION ANALYSIS In order to understand freight facilities demand in the city center and characterize the operation, rotation counts of freight operations were developed based following on-street parking analysis methodology presented in Cardenas & Cal y Mayor (2007). LEVEL OF SERVICE Loading and unloading performance analysis methodology found in Alho & Silva (2014) was selected as the most appropriate for this context, due to there is a high dependence on bay infrastructure for loading and loading operations and because this methodology was developed in a context of low data availability. STAKEHOLDER ANALYSIS Multi-Actor Multi-Criteria Analysis – MAMCA (Macharis et al., 2010) permitted to conclude that a combined set of strategies for loading and uploading operations in city centers should be implemented to raise parking offer and adapt to different demand conditions in terms of schedules and vehicles sizes. Some strategies requires a strong set of public incentives, including tax benefits and land price controls for logistic use. For this MAMCA analysis the surveys were completed as follows: 10 from Shippers/Carriers, 101 from receivers (Question PRO application used), 6 from authorities, 3 from residents (community leaders) and 2 from academics. According to the Cali Economic Census (DANE, 2006) there are approximately 4222 economic units in Cali city center, of which 23% belong to the retail trading sector for food, drinks and tobacco, the biggest group (CIIU Code 5211 of Chamber of Commerce). We decided to start our research with this type of commerce (971 units) and we have obtained responses from approximately 13% of them, so this represents a statistical confidence level of 90% (Torres, Paz, & Salazar, 2006). We developed 9 questionnaires for the enterprises that can represent approximately the 18% of the total shipper size in Cali city center (Bavaria, Coca-Cola, Productos Cárnicos, Productos Enrico, Distribuidora Colombina, Distribuidora Alpina, Pollos El Galpón, Quesos la Florida, Nutresa). We also interviewed 9 trade leaders and managers of parcel transport companies, (Cavasa, Andi, Adicomex, Sociedad Portuaria, Gids, Posey (International Freight Forwarders), Fedetranscol, Concretesa (Project’s Manager), Fenalco, Grecocentro).

1. Rotations analyisis was a field work in cooperation with the major office of Santiago de Cali. It requires only excel analysis. 2. Level of service analysis requires geo-referenced information about commercial establishments and bay availability. establishments informations was obtained from the chamber of commerce office, and bay availability was information identified in field work. Information was analysed in a Geographic Information System Software, ARCGIS Software. 3. MAMCA analysis was based on field questionnaires and it was analysed in Excel.
