Road Assets Management needs system where to handle all the dataRoad Assets Management needs system where to handle all the data

The Road Database (RDB) in a necessity is a road authority wants to plan for road maintenance and to maximize economic returns of investments made for the road network.

The ultimate objective of the RDB is to create a fundamental basis for planning and budgeting of the road maintenance activities.

RDB will provide planners, engineers and decision-makers alike with up-to-date information on the road network – its basic characteristics, condition, traffic fleet using the network etc..

The RDB is used to justify the need of adequate funding for routine maintenance of the road network, and it can also be used to prioritise specific maintenance and major upgrading projects.

The database itself is not any planning tools as such. Other software and applications to utilize the data are necessary. The PIARC HDM-4 is the most common tool to be used in maintenance planning and prioritising.

The amount of data is HUGE and therefore an effective system is needed to handle it all!

International experience shows that with “optimal” timing and scheduling of works, total road transportation costs (road agency and road user costs) can be reduced by up till 30 per cent. On the other hand, efficient data collection costs only 2-3 % of the maintenance budget (Source: International Experiences in Restructuring the Road Sector by A. Talvitie WB).

Data collection is economically feasible in normal circumstances and on that account it is recommended.

To establish a Road Assets Management System (RAMS) is a long and demanding process which needs lots of training, commitment and firm expertiseof the personnel working with it.

As a reward being commited into objective and economically feasible roadmaintenance, there will considerable savings in maintenance, better roadcondition and safer road network. Most important of all – happier road users!

Road Condition MeasurementsRoad Condition Measurements

•What is road condition?

•What is good and what bad road condition?

•Does opininon differ between people?

•What is the trend of road condition?

Answer: Objective means to measure the road condition are needed!
