Jabatan Kerja Raya Sabah’s Road To GIS SuccessPRESENTED BY:
Leong Shing Yau @ Saifuddin
Principal Assistant Director, Road Maintenance Branch
JKR Sabah
Road Maintenance Branch• Manage and maintain all JKR
registered state and federal roads in Sabah (except bridges and slope/embankment)
• Administer and manage road reserve in accordance to sections 77,84, 85 and 85A of Road Transport Act 1987 (Act 333)
MISSION• To ensure safe, reliable, and efficient
movement of people and goods on existing JKR Sabah roads
Meet the expected rate of
return on investment

1995Developing database for road maintenance works
MS Access 2.0,MS Access 95-2003
Desktop version
Kudat district
1995-2006
• ArcGIS 1st procured in 1998 •Without standards and specifications• “Dump” layer digital road map• View (in district) by ArcGIS Explorer only• Better than hardcopy map• Good for presentation and report• Not good enough for our needs and
requirements
1998-2012
• Pilot study in 2012-2014• GIS-based road asset information
management systems (RAIMS)• Location Referencing System Standards and
Specifications• Issues:• ICT infrastructures• Data collection

2018-2022 Current Initiative

Advanced linear referencing system (ALRS) road network base-map
GIS-based road information management system
Future development
What is ALRS Road Network Basemap?
Spatial Referencing System Linear Referencing System (LRS)Advanced Linear
Referencing System (ALRS) Road Network Basemap
Express location address in terms of spatial co-ordinates with respect to the earth, e.g. easting, northing, and elevation (X, Y, Z)
Identify the address of a point by measuring offsets from a known point along a constrained path, e.g. km2.345 Jln Sembulan
A reference or basemap which incorporate both linear and spatial referencing systems and would allow application of linear referencing within GIS enabled application environment
Could not represent location in terms of geometry shape/length effectively
Preferred method in referencing road data, e.g. location of culvert, works on a section of road, etc.
Few people could visualize spatial address physically
Simple, commonly use in our daily life and easily understood by most people

Why Do We Need ALRS Road Map?
• Both spatial and linear referencing methods are essential in our daily life and in any road management system• A common, standardized and consistent
linear referencing road map for all users in a easily understood format• Allow JKR SB to develop and establish an
effective GIS-based road management and maintenance system
Why Do We Need ALRS Road Map? …cont’d
• Allow infrastructure asset management system by other branch within JKR SB to be integrated and talk to each other •Would streamline greatly JKR SB’s
management & operation through visualizing, sharing, analyzing, monitoring road assets data etc. in ways that would not be possible before
