3 Status of urban freight demand data collection Existing studies and surveys The extent of urban freight demand data collection is, in general, quite poor. A call for tender for a pilot statistics study on urban freight has been launched last year by the Italian Ministry of Infrastructure and Transport. We have no information on the status of this activity. Other relevant database / studies concern specific cities where urban traffic planning or the implementation of urban logistics projects required a preliminary freight traffic data analysis, e.g. Rome City Center, STA, [data for 1999] Milan area, Da Rios G. e Gattuso D., 2003 [Data for 2001] Padova, Genova, Siena: studies for transit point implementation Bologna, Ferrara, etc: studies for the definition of urban freight policies or of the PGTUs (Urban traffic plans) / European projects 22/09/2005 P.

4 Existing studies and surveys - Example Politecnico di Milano, La Mobilità delle merci nell area Milanese, 2003 Period Content Counting of traffic flows Cordons interviews to commercial vehicles drivers to elaborate O/D matrix Interviews to commercial activities owners Elaboration of statistical data from other source on composition of commercial activities Exercises of Stated preferences with commercial activities owners Client Milan City Authority 22/09/2005 P.

5 Existing studies and surveys - Example Politecnico di Milano, La Mobilità delle merci nell area Milanese, 2003 Vehicle flows at the inner cordon Distribution of incoming motorway toll station flows 22/09/2005 P. Guglielminetti, PwC 5/13

6 Existing studies and surveys Alternative sources for urban freight distribution are the detailed and continuously updated files of transport operators. For some segments of the urban freight transport, e.g. the express couriers, these files are on electronic form. The production of detailed matrixes of parcel flows is (technically) quite easy. Main express couriers take advantage of such data for their transport flow optimisation. Such data could be an helpful support for improving the knowledge of urban freight transport, since they are more accurate than questionnaire surveys and more easy to be updated. However, availability of this data is not assured. 22/09/2005 P. Guglielminetti, PwC 6/13

7 Existing studies and surveys - Example PricewaterhouseCoopers, Performance improvement analysis for express couriers Period Content Collection of shipment data on local areas (origin / destination) Analysis of the existing local distribution organization (number of routes, average number of stops / route, average number of parcels collected / delivered per stop, number of km per route, total number of parcels collected / delivered per route, etc.) Cost reduction by redesigning / aggregating the routes Construction of a performance-related payment system to vehicle operators Client Major italian Express Courier operator (> 50 mn shipment / year) 22/09/2005 P. Guglielminetti, PwC 7/13

8 Existing studies and surveys - Example PricewaterhouseCoopers, Performance improvement analysis for express couriers Number of shipments / day (collected / deliverd) Routes zoning Routes characteristics 22/09/2005 P. Guglielminetti, PwC 8/13

9 Organizations responsible for data collection No national body is responsible for collecting data on urban freight. ISTAT (national statistic institute) road freight data concern only vehicle with with max gross weight > 3,5 t. Local authorities, as Municipalities or Provinces, collect data, in an independent way, in order to formulate general plan of transport at local level (PGTU, Piano Generale dei Trasporti Urbani, Urban general plan of transport). 22/09/2005 P. Guglielminetti, PwC 9/13

10 Status of data collection on urban freight transport supply Freight vehicle fleet Good vehicle fleet licensing data are collected by the PRA Pubblico Registro Automobilistico (Vehicle ownership registry) Data can be extracted by vehicle size and by area Data collection takes place in real time, since the registration of changes in vehicle ownership is compulsory The Automobile Club of Italy, managing the PRA, publishes a periodic bulletin and an Annual Statistic Yearbook with aggregated data. Most of these publications do not present data by vehicle size, so that it is difficult to isolate the local distribution vehicles. 22/09/2005 P. Guglielminetti, PwC 10/13

11 Status of data collection on urban freight transport supply Urban freight costs and prices Operating costs: specialized press publishes periodic analysis on costs (e.g. Tuttotrasporti) Prices charged for transport services: some transport operators published data on prices on their web-sites. Real prices charged to customer, however, depend a lot on the total number of shipment, on the frequency, etc. For some kind of transport, the prices are charged for a daily collection service on annual or seasonal subscription basis (e.g. laundering service for hotels and restaurant). So, the price structure in urban freight is very complex. 22/09/2005 P. Guglielminetti, PwC 11/13

12 Status of data collection on urban freight transport supply Infrastructure Capacity and layout of roads is generally available from Municipal Authorities (in many cases are GIS-Based data) More detailed data, such loading / unloading parking places, are not always recorded and updated The STA study for Rome counted 197 parking places for freight distribution in the city (only 14% of the drivers declared to use always or often those places, in most cases because they were occupied by other kind of vehicles). Data on nodes (shipment collection branches, hubs, etc.) of private freight transport operators are generally available only from the operators themselves; this kind of information is very rarely collected / analysed by freight traffic experts 22/09/2005 P. Guglielminetti, PwC 12/13

13 Conclusions Data collection on freight transport in urban areas, in Italy, is not well developed. Only few study at local level has been run in the last years and there was no co-ordination among the different administrations or group that have run these studies. This is probably due to the absence of a institutional body in charge of studying, co-coordinating studies and summarizing data collected at local level Knowledge on phenomena, however, is likely to improve in the next year, because of growing political attention on the issue. Alternative sources for urban freight distribution are the detailed and continuously updated files of transport operators. In order to make available these data, operators should be involved in the process of data collection / analysis & policy making. They should perceive an advantage resulting from the surveys. 22/09/2005 P. Guglielminetti, PwC 13/13
