  1. Building Road Data Base for More Effective Road Asset Management Timo Saarenketo, PhD Managing Director Roadscanners

  2. CONSULTING - SOFTWARE - R&D - ROAD SURVEYS – INSTRUMENTS Focus: existing traffic infrastructure management

  3. ROADSCANNERS SPECIAL EXPERTISE: • Low traffic volume road management

  4. ROADSCANNERS SPECIAL EXPERTISE: • Road materials, their strength and deformation properties and testing methods

  5. environmental impact Road Assets Management needs system where to handle all the data

  6. Background 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!

  7. Background 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 expertise of the personnel working with it. As a reward being commited into objective and economically feasible road maintenance, there will considerable savings in maintenance, better road condition and safer road network. Most important of all – happier road users!

  8. RDB Roadscanners/Sirway Road Data Base Road Data Base (RDB) - solution • Components • MyODBC software for database connection • MySQL database core • MySQL Administrator • MySQL Query Browser • Road Data Base (RDB) user interface Road Data Base

  9. GIS Data flows in road data bases Basic information Accidents Maintenance programming Traffic counting Projects/Prices Condition inventory Devices Strategic planning Road Data Base Long term forecasting Theme maps ! Standard reports

  10. Road Data Base (RDB) user interface Easy and user friendly!

  11. Road Data Base - contents

  12. Roadscanners/Sirway RDB - activities • View regions, roads and sections • Create and delete roads • Create and delete sections • Create and delete accidents • Create and delete location reference points (LRP) • Create and delete projects • Create and delete road furniture and road side activities • Create and delete traffic • View and modify road and section properties • View and modify survey unit condition data • View, add and delete photos of roads • View and modify traffic data • View and modify accident data • View and modify LRP data • View and modify project data • View and modify road furniture data • View and modify traffic data • Add ,view and delete accident, project, road furniture and LRP photos • Import data from text files (CSV) • Export data to text files and HDM-4 software format • Generate reports and strip maps • View and modify settings • Generate survey plans • Change road alignment • Utilise additional tools • Modify condition index equation • Calculate condition indexes • Calculate AADT • Estimate missing AADT • Estimate missing central deflection

  13. Benefits • Easy user interface • Transfer into HMD-4 is solved • (network, homogenous sections or road matrix) • History information (what has been done and where?) • To handle changes in road address, lenght etc has been solved • Includes also accident sand road side attributes • Several different reports Tayloring / customizing into Russian circumstances easy! Tested in real life in Azerbaijan, Papua-New-Guinea and Pakistan!

  14. Conclusion - Why Road Data Base is needed? Functional RDB is a base for systematical and objective road maintenance! Data can be used also in long-term stratetic planning in HDM-4 or similar. Right acts in right locations in right time will benefit everybody!

  15. Éstablishing Road Data Base – What is Deeded? • 1. DESIGN OF ROAD DATA BASE AND DATA COLLECTION • Design of road data base • Investing measurement units, computers and software • 2. DATA COLLECTION • GPS surveys on roads • Video / still photo data collection fro road network • 3. PROSESSING SURVEY DATA AND TRANSFORM TO DATA BASES • Establishing final road route data base • linking video and pictures files to data base • 4. IMPLEMENTATION PHASE 1/5/2020

  16. Road 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!

  17. Road condition measurements • Why road condition measurements are needed? • STRATEGIC PLANNING • Road condition in network level • Road condition trend in network • Optimal budget need • Optimal work standards • Comparing the regions to each other • MAINTENANCE PLANNING • Allocate the maintenance budget and resources to right locations • Scheduling the maintenance work • PROJECT PLANNING • What are the reasons for bad road condition • How the road should be repaired (Road analysis)

  18. Condition measurements with Roadscanners´ RD Cam Link – together with road data base data collection Audiocomments Digital Video & Still pics DGPS coordinates

  19. ROAD DOCTOR CAM LINK OUTPUT • Documented general road condition • Pavement distresses • Spring time weakening • Traffic signs and other devices • Road markings • Condition trends (time series)
