The European project VIVALDI was set up to provide innovation and results in the each of the EU CIVITAS policy fields that aimed to improve transport in urban areas. These included clean vehicles, goods distribution and telematics. Bremen had already participated in the project as the first application dated back to the 1990's. The update of the CL project included several recommendations. These included using two low emission trucks (CNG (compressed natural gas) and bio-diesel) for testing and implementing efficient City-Logistik GmbH goods' distribution. Routes were also to be optimised by using modernised IT-communication equipment and the bundling of delivery trips to large shopping malls. Other activities included testing a new city-centre oriented concept and demonstrating a delivery service to shop keepers. Initially, four low emission delivery vehicles were intended and four routes set up inside and outside of Bremen. The project was unable to purchase a CNG vehicle however, due to non-delivery and high cost. Instead, a bio-diesel truck was purchased in order to assess economic and ecological impacts and to test the new online telematics systems. The intention was to provide more efficient, cleaner transport to key target areas. End users included freight operators in the central business district of Bremen and shopping centres in suburban areas. Potential barriers to the growth of the City logistics scheme included the fact that usually only transport services were involved and value-added- services were often missing. The structure of the project partner, City-Logistik company contained mostly couriers rather than retailers, resulting in a high level of competition. There were also challenges regarding the exchange of data, collections and different interfaces, plus an increase in the number of smaller shipments, which made the grouping of the goods difficult. Economic difficulties could be experienced after ending the model of financial support (for example the high costs of the grouping of the goods threatens economic success). Furthermore, a city logistics company which concentrated on delivering only to the city centre was not found to be viable. Successful companies make their money by fulfilling their customers' specialist needs. A policy promoting regulatory support is required in order for city logistics companies to remain viable.
