CONTENT 1.Review: use of criteria (effectiveness of transport system, financial, economic, social) for evaluation of transport, estimation of impacts for those categories 2.Illustration of the use of modelling for planning of Perintis transport Inter-island container transport 3.Conclusions – follow up Potential of the approach Expansions in view of current transport policy questions
3
1) Review on criteria and impact estimation
4
Framework for design and evaluation
5
Effectiveness of the transport system Example Perintis: –provide the transport service in the most effective way fulfilling the demand for transport (frequency of service, minimum transport time), –with the best input of ships and combination of ship tours
6
Financial impacts Example Perintis: –Standpoint of provider/sponsor Operation cost for providing the service Revenue from the service for a particular price setting Cash balance: need for subsidy? –Standpoint of user cost of the service
7
Economic impacts Total effect of an improvement of transport on the welfare of the country/region Improved transport has a direct effect on some sectors of the economy but these effects propagate into related sectors Macro-economics has a modelling approach for this: Input- Output (I-O) modelling To include regional differences and transport a special version of I-O is available which includes trade between regions : a spatial I-O (Spatial Computable General Equilibrium model SCGE)
8
Economic impacts In macro-economics transport costs are called transaction costs; reduced costs improve trade and economic performance Problem: how well can the activities be supported by Perintis (small businesses, local) be included in the SCGE? Little data on those activities; how well are they represented in the modeling? Region A Region B Trade Transaction costs associated with transport
9
Social impacts Most difficult to determine and estimate; not included in economic modelling Basically the analysis of how Perintis improves the lifes of people should be carried out at the micro-level Which standard of minimal service frequency should be provided? When can a transition be made to commercial service? An ability to pay analysis could indicate if commercial service can be afforded. However the remoteness of the place also a plays role because transport to such place maybe very expensive due to low load. Conclusion: evaluating/justifying transport subsidy to low income users and/or a disadvantaged part of the network is difficult (universal problem)
10
Quantification: challenge for transport planning Ability to quantify the functioning of the transport system and the impacts is necessary to compare alternatives In the present presentation focus is on quantification (modelling) to enable an assessment of transport effectiveness and financial impacts Applications –Subsidized Perintis service –Commercial inter-island container transport
11
2) Illustration of the use of modelling in transport planning (Perintis, Inter-island container transport)
12
Modelling basics
13
Transport analysis: supply - demand Demand for transport Supply of transport facilities employment social transport modes vehicle fleet(s) infrastructure trade Transport market: equilibrium/performance … … Value generated Implementation cost
14
ADB TA8045: analysis framework Demand for transport (O-D matrix) Transport supply system (infra, routes,…) Match of supply and demand Performance of transport system (revenue, ….) Design of improvements to the transport system Projection of economic activity Cost analysis (life-cycle) Transport model (Omnitrans) Base map (GIS) Spreadsheets / Matlab Spreadsheets Mapinfo, Arcinfo Demographic/ economic models Survey + secondary data Spreadsheets
15
Components of the framework 1)Demand estimation/monitoring: analysis of monitoring data, design and execution of a survey 2)Modelling: implementation of the Omnitrans transport analysis software including training 3)Cost analysis: derivation of life-cycle cost for shipping 4)Design of improvements to the Perintis service: Maluku case study

28
Criteria for design of the transport service Accessibility or Connectivity? –Connectivity is usually used in the context of the economy: economists think about how the economy is connected and performing; better connection means less transaction costs and better economic performance –Accessibility is usually used in the context of transport: a transport engineer/economist thinks in terms of improving the transport service; how well can a certain place be reached using the available transport facilities Basically the two concepts relate to the some thing in a different context Typical formulation
29
Criteria for design of the transport service Typical formulation of Accessibility –Usually a gravity type expression is used –The availability of public services can be considered proportional to the size of the population of a particular site. The accessibility of a site i will be proportional to the size of the population centers in the neighborhood and inverse proportional to distance to reach those centers. Further of importance is the frequency by which the connection is provided, a higher frequency results in a higher accessibility. Ai : accessibility Dij : distance to reach j from i Pj : population in j Fj : frequency by which the connection form j to i is provided m : nodes (population centers) in the network connected to i Dij : shortest route to reach j from i with available transport (provided by Omnitrans) Typical formulation
30
Example accessibility
31
Set up of Maluku case Accessibility index: only relative indicator; gives overall impression of the differences in region, where most action is needed; not sufficient/detailed enough to make new design of the transport service Present approach: comparison existing situation with a new design using 5 more detailed criteria (elaborated below) Using rational concepts/judgement (reduced length of tours, avoid overlap, hub and spoke,…) a new set of 11 tours has been defined; this is compared with the existing situation (15 routes) using the 5 criteria

34
Criterion 1: travel time performance
35
Criterion 1: travel time performance (cont.)
36
Criterion 2: access time
37
Criterion 3: number of visits - effectiveness Existing 15 routes New 11 routes Total number of visits 7460 Total number of visits 4910
38
Criterion 4: life-cycle cost Reduced number (4) of ships : saving 40 bln Rp/year
39
Criterion 5: passenger.miles – consumer cost Passenger miles: –Existing : 29 mln –11 route : 21 mln Reduction consumer cost with 11 route: 1,5 bln Rp/year Subsidy = cost-revenue Existing (15 routes) 150 – 5,5 = 144,5 bln Rp/year New (11 routes) 110 – 4 = 106 bln Rp/year
40
Evaluation summary Criteria 1: travel time distribution is the same Criteria 2 : slight improvement of the access time Criteria 3: –existing situation: very large variation of visits among the different ports –new route service: visits more equally distributed among ports but overall a reduced number of visits to ports Criteria 4: –the overall cost for the ship operator/sponsor is the following: 40 blnRp/year (cost savings) – 1.5 (reduced revenue because more efficient travel) = 38,5 blnRp (cost saving) –Total Subsidy (Maluku) : from 144.5 to 106 bln Rp/year Criteria 5: reduced consumer cost : 1,5 blnRp/year (cost saving) The new 11 route system represents a win-win proposal for operator/sponsor and consumer
41
Evaluation summary (cont) Observation: visit to most ports is about 1 per week Socially acceptable? If visitation needs to be higher then this will increase the cost ; trade-off between social standard and cost

Role of scale effects in maritime transport Globalization is driven by developments in maritime transport (world-wide: 90% of total ton.km) : scale effect, logistics harmonization in corridors Transport and Communication Costs Indexes, 1920-2000;
46
Role of scale effects in maritime transport To which extent can such scale effects be realized on the Indonesian network? What is needed to realize them? The following analyses have been carried out to find out: –Preparation of container transport cost model (variables: demand volume, distance, ship size, load factor, logistic efficiency) –Analysis of options for the national network (using transport model)
47
Illustration scale effect (using cost model) Demand: 100 TEU/day

What are the prospects for reduction of domestic container transport cost? Analysis approach We like to know what is possible in 2030 Pro-active planning of improvements to shipping and network, and increased demand by 2030 Set-up: –Demand projection for 2030 –Design of supply system for 2030 –Matching demand-supply

3) Conclusions – follow up
61
Conclusions Observation: detailed quantification of the transport systems and their impacts strongly facilitates the analysis of alternatives Maluku case: –optimization results in 25% reduction in cost (=40bln Rp/year) for same service; – application to the total Perintis East-Indonesia (67 routes) may potentially result in a total savings of 18 tours (indicative 180 bln Rp) Inter-island container transport: strong reduction (50%) in the cost of container transport possible
62
Conclusions (continued) Economic/social justification of Perintis: represents most difficult assessment because of the social dimension of the service; difficult to determine the standard of the service, and to estimate its value to the welfare of the country Set up of a commercial transport service is much easier (supply can follow demand) Modelling provides a systematic tool to analyse the many alternatives for setting up a maritime highway and in particular address the challenges for East-I. Follow up: –Transport Demand estimation (passenger, cargo) linked to the national (CBS) socio-economic data base would be an important expansion of the modelling and its data base
63
Demand projection from socio- economic/land-use data National data base (CBS) Monitored demand data Estimation of relationship(s) Projected socio- economic/land- use conditions Projected demand
