  1. BUTE Department of Aircraft and Ships Formula and indicators for Sustainable Transportation Performance Index Daniel HADHAZI - Prof. Jozsef ROHACS - Gyorgy BOGAR - Csaba HARGITAI - Gyozo SIMONGATI Presented by: Daniel Chikany PhD studentBudapest University of Technology and EconomicsDepartment of Aircraft and Ships

  2. 1. Definitions Indicator: a variable selected and defined to measure progress toward an objective Index: a group of indicators aggregated into a single value General indicator: related to the selected transport mode - used for assessment on macro level Process indicator: related to the whole transport process - used for assessment on micro level Specific indicator: related to a particular transport case - used for assessment on micro level

  3. 2. Indicators First step: selection Collection of the process indicators Collection of the general and specific indicators - for road - for rail - for inland waterway transport - for port cargo handling Ranking the indicators by its importance Marking of indicators that it is important from the logistical, economical, environmental and safety point of view Selection of the indicators to be included in the determination of STPI

  4. 3. Assessment The assessment is made for the various sets of indicators both on macro and micro level • Proposed method: • 1. Evaluation of the indicators • some of them are exact, measured, calculated or estimated values, statistical data • some are “quality” characteristics 2. All should be quantified on proper scales (1-3; 1-5; 1-10)

  5. 3. Assessment Example: Process Indicator: Volume of cargo transported assessment from the logistical point of view

  6. 3. Assessment 3. Normalization a “4” on a scale with 10 divisions is 0.400 a “2” on a scale with 3 divisions is 0.667 we get the normalized value (NV) of the indicator • 4. Weighting • by the degree of importance • by the complexity of the indicator (only on micro level)

  7. 3. Assessment 5. Calculation of the performance index (PI) on macro level - by using the general indicators PIaspect = Σni=1(wfi * NVi) / Σni=1 wfi the result is PIlog , PIeco , PIenv , PIsaf for the different modes and the STPI in general is: STPIgeneral = (wflog * PIlog +wfeco * PIeco +wfenv * PIenv +wfsaf * PIsaf ) (wflog +wfeco +wfenv +wfsaf)

  8. 3. Assessment 6. Calculation of the performance index (PI) on micro level - by using the process- and specific indicators PIaspect = Σni=1(wfi * NVi) / Σni=1 wfi the result is PIlog , PIeco , PIenv , PIsaf and the STPI for the particular transport case is: STPIspecific = (wflog * PIlog +wfeco * PIeco +wfenv * PIenv +wfsaf * PIsaf ) (wflog +wfeco +wfenv +wfsaf)

  9. 4. Summary Advantages of the method: • general and task-specific assessment can be made • - gives information for the transport policy makers • - on a company level comparison between alternatives for transport from A to B can be made • the sustainability can be assessed separetly by different aspects • - hence the effects of the different aspects on STPI can be seen • simple • well-defined • the future also can be modeled • “objective” • a short program for the calculation can be easily written • the sensibility of STPI can be checked easily
