Railways: km public transportation Of which km are electrified Roads: km state roads km municipality streets and roads km private roads with state subsidies Air: 52 approved airports Maritime: 700 fairways 50 public ports Facts about the Swedish Transport net work Population inhabitants Country size km² Density of population 23 inhabitants / km²

Organisation of the Transport Administration Divided into six regions with region offices and local offices

A Road Information System / Road Data Bank u Is the basis for a national road information system where amongst others transport companies can plan for best use of the available road network and thereby reducing total cost for transportation. u would form part of the transport layer in a geographic information system for nationwide physical planning. Road Information System vision

A Road Information System is u a structured set of data describing a well defined road network and related items, u necessary tools to supply and maintain these data u sophisticated analysis instruments to retrieve information in order to make better use of the road transport system. Road Information System The aim of a Road Information System is to provide u proper knowledge about current road conditions u good knowledge on cost and effects from actions u proper tools to analyze the effects of actions in order to prioritize and plan for the best use of available funds.

By using a Road Information System based on: u Necessary organization u Cost effective IT-infrastructure u Structured sets of high quality data describing a well defined road network and related items u Necessary tools to supply and maintain data u Sophisticated analysis instruments to retrieve information Available funds would come to better use. Road Information System strategy

Concept of the Road Information System Common platform for all road-related information Bridge- data Paving data Traffic- data Accident data RST- data Road data Road Net

Referencing System A need for a road network referencing model Need to be stable over time in order to compare data and support benchmarking from one year to another Make it easy for data collection, storing of data as well as analysing of data A various ways : *Link & Node concept (good for a Road Administration) *KM-Post concept (good for a Road Administration) *Road by road (good only for road inventories) *XY-coordinates (good only for mapping) *etc

Main road Junctions at Main roads Node (Link & Node, junctions to other roads) KM-post (1 km section) 1 km length Link & Node KM-post Referencing System continue

Road Information System actions A Road Information strategy u with attached vision and plans in order to have documents agreed by the management that determine what are the goals how to reach there what funds and resources are available to get there.

Road Information System actions A road referencing system u where all involved parties agree upon a persistent addressing scheme for relating items to the road network. u Where all collected road data must be related to.

Road Information System actions u A data catalogue where agreed definitions of road related items can be stored. u Solid definitions of every item that is going to be stored in the Road Information System. u An implemented data model that support for the proper connection between road network description and items related to the road network.

u The proper software tools for establishment, maintenance, update and retrieval of road network description and related items. u A solid description of data collection routines and quality measures for every item that is going to be stored in the Road Information System. u An organization responsible for data collection, data maintenance and quality measure for all data that is going to be stored in the Road Information System. Road Information System actions

Road Information System actions u An IT infrastructure for resource and data sharing which in reality translates into a computer network with common servers for all levels of the Ministry organization where data is secured and made available by means of Ministry standards. u An organization responsible for the development, operation and maintenance of IT strategy, road network, road referencing and IT infrastructure in order to cater for long term availability of road related information.

Road Information System plan u Road network description and road referencing are the first steps in the development of a road information system and have to be established before any programming and data collection of road items starts. u IT strategy can, and always will, be an ongoing effort but Organization and IT infrastructure can be introduced in steps and has to be fully established when the first version of the road information system is to be released.

RDB l Make it simple l Involve management l Integrate organization l Test before release l Be aware of critical choices l Support from the start Road Information System plan

Benefits of a Road Information System Information is available for those who need it, when they need it Structured data Easy follow-up Data with known quality Saves money Information

Information Management strategy and vision Vision without action is a daydream Action without vision is just a waste of time and effort Vision and its need of actions is collected and determined in the IT-strategy Information is a common resource and should flow freely Standards are needed for cooperation and give cost reductions Based on the current situation and the wanted situation Must be agreed by top level management in the various sectors Need to be done in steps Long-term covering 3 and 5 years Review on a yearly basis

The IT-strategy should include the following Main principles and organisation Tasks and responsibility to the IT-directorate as well as the end-users Technical aspects such as network, soft- and hardware, etc Standards and Applications Education at the Computer Department Training of the staff using computers in daily activities Time schedule Information Management strategy and vision continue
