Data Availability and Comparability by Sector in Northern Ireland and the Republic of Ireland Nicola Fisher & Naomi McLaughlin DRD NI
Document existing freight movement data sources Analysis of existing freight data sources NI & ROI Main sources- CSO (ROI), DfT (GB) and NISRA Data requested from each organisation - data related to NI - data related to ROI - data related to both NI and ROI
Document existing freight movement data sources Data Sources document drawn up by mode - Organisations (data providers) - Data Source - Data Summary Description - Collation Method (census, admin system) - Geographical coverage - Publication frequency - Published metadata
Assess North-South data comparability and highlight significant issues Comparability table by mode created: - availability of data (except rail) for NI & ROI - comparability of data - reason data aren t comparable - potential for comparability in future
Produce a report on findings and include key comparable data Report by sector has been produced detailing - availability, data issues, North- South comparability and potential information gaps
Road Freight EU legislation 1172/98 on statistical returns in respect of the carriage of goods by road. Should ensure comparability between EU nations. Gathering detailed European statistics on road freight transport and harmonising them has been the challenge of the Council Regulation 1172/98.
Main Sources of Data for Road Freight Department of Transport (UK) Continuing Survey of Road Goods Transport (NI), CSRGT(NI) CSO National Survey of Transport of Goods by Road Administration Systems in both Jurisdictions (DVANI, National Vehicle Driver File (ROI))
Data Issues for Road Freight Vehicle weight threshold CSRGT(NI) defines freight as having Gross Vehicle Weight (GVW) of > 3.5 tonnes CSO defines freight as having an unladen weight of > 2 tonnes No impact on freight definition but comparison not possible by vehicle type and weight
Data Availability & Comparability Available Comparable Reason for not being comparable Data NI ROI Potential for comparablility Road Freight: Tonnes carried Tonnes km Vehicle km Yes Yes Yes Yes Yes Yes Yes Yes Yes The difference in counting methodolgy will be highlighted and presented in the report. Number of Heavy Goods Vehicles (Figures for NI are an actual count of licensed vehicles at the 31st December on any given year whereas figures for ROI are the average number of goods vehicles within the scope of the survey) Laden Journeys Origin/Destination by NUTS III (EU Classification of territorial units for Statistics) Length of Haul Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes NI uses an older classification of NST code than ROI ROI uses unladen weight of vehicle and NI uses Gross Vehicle Weight Yes, can be provided on request from DfT Potentially, but may involve a large amount of calculation on either of the sample surveys. Type of Freight being carried (i.e. Foodstuffs/Crude Minerals/Miscellaneous) yes yes no By vehicle weight (Threshold for freight differs in ROI and NI with freight vehicles in ROI defined as having unladen weight of greater than 2 tonnes whereas in NI, freight vehicles is defined as having a gross vehicle weight of greater than 3.5 tonnes.) What proportion of freight is entirely internal? (i.e. NI vehicles with origin & destination within NI and ROI vehicles with an origin & destination within ROI) Yes Yes no yes data available for cabotage in ROI yes data available for cabotage in NI yes What proportion of freight is entirely cabotage (Please note that Data on cabotage in both jurisdictions is only available for NI, ROI and GB registered vehicles) Main times of day for travelling Switching of Mode (i.e. from ship to road etc. ) Van Freight data Yes data not available data not available data not available no no no no no no no no n/a
Trends in Road Freight Data Road Freight Activity in NI & ROI by vehicles registered in NI, ROI & GB, 2004 2009 Tonnes kilometres, Tonnes lifted, Vehicle Kilometres & Laden Journeys: 2004 - 2009 (Indexed to 2004 = 100) 120 110 100 90 80 70 60 50 2004 2005 2006 2007 2008 2009 Tonne-Kilometres Tonnes Carried Vehicle Kilometres Laden Journeys

Data Gaps Activities of Foreign Trucks How long do they stay? What are they carrying? Nationality of Vehicles and Drivers? Cabotage undertaken? Tonnes lifted / tonnes km / Vehicle km
Data Gaps Continued Extent of LGV/ Van Freight in Ireland Large amount of goods being transported by small vans & lorries. Significant increase in the number of LGV s since 2005 in NI No data on what they are carrying Van Activity Baseline Survey in England 2008 Statistics Norway have also researched van freight.
Maritime Freight EC Maritime Statistics Directive (Council Directive 2009/42/EC on statistical returns in respect of the carriage of goods and passengers by sea) Quarterly returns from ports collecting data by route, nationality of vessel and cargo type.
Main Sources of Maritime Freight Data Northern Ireland Northern Ireland Ports Traffic - DETI UK Maritime Statistics Report (detailed info on NI Ports) Republic of Ireland Statistics of Port Traffic CSO The Irish Maritime Transport Economist IMDO - also includes info on NI Ports
Data Availability & Comparability Reason for not being comparable Available Comparable Potential for comparablility Data NI ROI Maritime Freight Tonnes carried Yes Yes Yes Yes - with some combining of categories By freight type (e.g Ro/Ro, Lo/Lo) Yes Yes Some information available from DFT detailed report on NI's main ports Some data maybe comparable if categories are combined. By Commodity Partial Incoming / Outgoing Freight Yes Yes Partial (know the region that freight is departing from or arriving to) Partial (know the region that freight is departing from or arriving to) Departing/Arriving Port don t know where freight is coming from
Maritime Data Trends Total Tonnage of Goods Handled in NI & ROI P orts by Category of Traffic, 2002 - 2009 90,000 80,000 70,000 60,000 tonnes 50,000 40,000 30,000 20,000 10,000 0 2002 2003 2004 2005 2006 2007 2008 2009 Total Goods Handled Roll-on/Roll-off Traffic Lift-on/Lift-off Traffic Other*
Maritime Data Trends Breakdown of goods forwarded and goods received in NI & ROI 80,000 70,000 60,000 50,000 tonnes 40,000 30,000 20,000 10,000 0 2002 2003 2004 2005 2006 2007 2008 2009 Goods Received Goods Forwarded
Maritime Data Gaps Don t know what is being transported in Lift on/Lift off (Lo/Lo) containers or in the Roll on/Roll off (Ro/Ro) vessels.
Air Freight EC regulation No 437/2003 on statistical returns in respect of the carriage of passengers, freight and mail by air
Main Sources of Air Freight Data Northern Ireland Civil Aviation Authority (CAA) - compile administrative returns from airports. Statistics are published monthly / annually Republic of Ireland Aviation Statistics Survey data published annually in Transport Omnibus Report
Data Issues Double Counting of Airfreight Relates to very high value goods, e.g. computer chips Freight on Airway Bill before cost of transport determined Potentially more cost-effective to transport by truck to Heathrow for onward transportation to USA
Data Availability & Comparability Available Comparable Reason for not being comparable Potential for comparablility Data NI ROI Air Freight Tonnes Yes Yes Yes Known if arriving or departing from both jurisdiction s Known if arriving or departing from both jurisdictions Departing or Arriving Airport Yes Weight of Freight (tonnes) Yes Yes Yes Type of Freight No No No Whether Incoming/Outgoing Freight Yes Yes Yes Yes, have separate mail figures for NI so can add mail figures to freight to enable comparison. Mail is included in ROI figures Mail Included no Yes No
Air Freight Trends Total tonnage of goods handled at NI & ROI Airports 200,000 180,000 160,000 140,000 120,000 tonnes 100,000 80,000 60,000 40,000 20,000 0 2004 2005 2006 2007 2008 2009 2010 Total ROI Total NI
Data Gaps for Air Freight No significant air freight gaps identified yet
Rail Freight Rail Freight ceased in NI in 2003 Data for ROI is provided by Iarnr d ireann and published in CSO Transport Omnibus on an annual basis
Rail Freight in ROI Rail Freight carried by Iarnrod Eireann (2003 = 100) 120 100 80 60 40 20 0 2003 2004 2005 2006 2007 2008 Freight Traffic Tonnes Freight Traffic Tonnes Kilometres
Rail Freight Data Issues Bord na Mona Extensive private rail network which is used for carrying Peat to power stations & other businesses 3.3 million tonnes carried in 2008 Data not included in the CSO Statistics
