1 PLS 308: Damage, Loss and Needs Assessment Infrastructure Transport, Telecommunication

2 Transport Sub - sectors Road transport Railroad transport Air transport Water transport Communications Fixed-line systems Telecommunication systems 2

3 Damage and Losses Damages in transportation subsector components Primary, secondary, and tertiary roads Bridges and drainage structures Railroads Vehicles and rolling stock Ports, river navigation channels, boats and ships Airport terminals and planes Communications system components Losses Higher transport costs Use of lower quality or longer roads Change to different transport modes Delays in transit or cargo loading/unloading times Use of lower capacity vehicles Lower revenues Transport companies Port and airport enterprises Communications enterprises Note: the value of losses might be higher than the value of damages give priority to speedy reconstruction 3

4 Teams and Data Data Requirement Road traffic data for each main road section (before and after disaster) Unit operating costs for different types of vehicles under different types of roads Timeframe for repairs or reconstruction of road sections Information Source Ministry of Roads Ministry of Works Ministry of Planning Feasibility studies of new road projects Other private sources Team Composition Civil engineers Road transport specialists Railway transport specialists Air transport specialists Water transport engineers Communications engineers Transport economists with specialization in each mode of transport 4

5 Road Transport

6 Losses in Road Transportation Additional expenses to enable essential traffic flow after disaster Higher road transport costs due to Utilization of alternative, longer routes Use of lower quality road surfaces Utilization of alternative, higher-cost transport modes 6

7 Estimating Higher Transportation Costs Compare: Pre-disaster traffic flows Post-disaster flows Estimate marginal operating costs of vehicles under baseline and post-disaster traffic conditions including alternative modes of transportation (in US$/km for each type of vehicle) Estimate time required for repair and reconstruction of damaged road sections Combine these to estimate the amount of increased costs 7

8 Other Transport Sub-sectors Water, Air Transport and Telecommunication

9 Losses in Sub-sectors Water Transport Higher Operational Cost Longer waiting times at ports Transfer to higher-cost alternative transport modes Use of smaller vessels and increased number of trips Dredging of river and port channels Use of lower capacity vessels during drought times Air Transport Higher Operational Costs Use of alternative, far-away airports Use of lower capacity airplanes Telecommunication Lower Revenues Lower port revenues Lower transport enterprise revenues Lower revenues Temporary closing or partial operation of airports Reduction in number of passengers and tourists Lower revenues Non functioning of land-based telecommunication system (i.e. flooding of switchboards or cable lines) Non functioning of wireless systems (realign antennas or electricity outages) 9
