2. Kerala –God’s own country
Located on the south western tip of India
Narrow Strip of Land; 600 km long, 100 kms wide.
Area – 38,863 sq km (1.27% of India’s land area)
Climate – Tropical with 3 main seasons
Geography
a mountainous western ghats towering m
midland region with sprawling plantations & paddy fields
coastal plains with stretches of backwaters
Population – million
Population density – 819 per km2
74% living in villages 19

3. Kerala Road Network
Kerala has a wide network of roads though poorly developed and congested
Total length of road - 1,54,679 km
Length of PWD Road network – 27,704 km
Balance roads with LSGD and other agencies
Road Density 398 km/100 sq.km 18

4. Road Maintenance & Management System (RMMS)
PWD Road Length
28 July 2005
Length of PWD road
NH – 1,524km
SH – 3,928 km
MDR – 22,252 km
Total PWD – 27,704 km 17

5. Road Maintenance Problems
Faster deterioration of roads due to
Heavy seasonal rainfall
Insufficient pavement strength
Increase in traffic (8-10% every year)
Inadequate drainage system
Issues with Road Pavements
Pavement condition shows severe distress e.g. cracks, large potholes, edge breaks
Shoulders are damaged with high edge drops 16

6. Inadequate Road Maintenance Funding
Base Year: 15

7. Road Condition based on IRC Standards14

8. Road Maintenance & Management System (RMMS)
28 July 2005
Solution RMMS..??
Report of the Committee (IRC-2001)
“Norms for maintenance of Roads in India”
“ For optimum utilization of the meager funds and prioritization of the development and maintenance works, it is of urgent necessity to introduce the Maintenance Management System both for pavement and bridges. This system has to be computer based and using Highway Design Model developed by WB updated to HDM-4.” 13
Wilbur Smith Associates Inc.

9. Solution -RMMS..??
Government decided to develop “GIS based Road Maintenance Management System” through Technical Assistance
Included in the Institutional Strengthening Action Plan (ISAP) of WB funded Kerala StateTransport Project (KSTP)
Developed through two different projects
Road Maintenance Management System(RMMS)
GIS based Road Information Management System (RIMS)
Integrated to function as GIS based RMMS 12

10. RMMS Project Objective Project Details Project Status
To develop a HDM-4 based Road Maintenance Management Systems for PWD linked to GIS system
Project Details
Consultant - Wilbur Smith Associates
Project Cost – 32 Million(INR)
Project Duration(24 Months)
Project Status
Project Completed on Sept 2006
Central RMMS Unit formed in PWD
HDM-4 based system implemented
Proposal for fresh data collection 11

12. Data Collection issues
Road Maintenance & Management System (RMMS)
28 July 2005
Data Collection issues
Data collection before starting the project
Qualitative data ( not confirming to HDM-4)
Road names are not matching with PWD registers
Linear Referencing Problems ( start and end)
Variation in Road Length
Ownership for the data
Data was unusable for RMMS 9
Wilbur Smith Associates Inc.

13. Data Collection issues
Data collected through the project was 30 %
Required interpolation to make it statewide
Very minimal traffic data
Roads are curvy, closer segments
Variation of elevation
Too many assumptions 8

14. Organizational issues
Awareness on RMMS
Dedicated Cells
Resources
IT Infrastructure
Financial Delegation
HR & Training 7

15. Technical issues Calibration of Bumb integrators Calibration of HDM-4
Physical referencing ( km stones)
History of maintenance works
Issues with Road Numbering and Road Code
Road Jurisdiction and Overlapping Problems
Integration with GIS system 6

16. Challenges Parallel implementation of GIS and RMMS
Change management issues
Computer awareness
Physical infrastructure
Counterpart staff
Low motivation.
