The development of the Road Asset Management System (RAMS) http://www.mp-rams.co.za/ for the Mpumalanga Provincial Department of Public Works, Roads and Transport involved a complete redesign of the previous Road Asset Management System used by the client including all sub systems.
This included a RAMS system framework design, sub-system integration design, server and communication interfaces design and procurement, web-based data logging and interactive platform design and implementation, GIS setup and management for all the sub systems, training of Departmental employees on using the RAMS interactive system, map design and production.
Lidwala developed and implemented an online resource of road related data with easy access to the road inventory information and other related features e.g. National roads, farm descriptions, population density, school locations, landuse and bridges.
The GIS was built in a stable, secure server environment with cross platform (Linux, Windows Server and Apple) and cross browser (Internet Explorer, Firefox and Chrome) ability with minimal annual software cost.
One of the objectives was to implement the system in such a way that it was robust, easy to use and that it became an important tool to the client by providing invaluable insight to decision making.
Visual Condition assessments and manual traffic counting are conducted annually whilst Profile measurements are conducted every three years. The Road Network Inventory (RNI) is updated with validated feedback from the visual assessments. A dTIMS analysis is run on the consolidated dataset.
A very important aspect of any RAMS is the ability to spatially locate items and events on the RNI. This involves defining the RNI in spatially using road centrelines and assigning directionality and chainage to the road links and using some form of Linear Referencing System (LRS). The result of a LRS query in the RAMS, being a 10m Profile measurement section dynamically created from the RAMS database using the LRS implementation, is displayed the following screen print.
To allow for the historic aspect of the RNI to be interrogated, a historisation mechanism was implemented in the database. This allowed for changes in data over time in the RNI and related road conditions and traffic data to be tracked, queried and analysed.
A Google Earth panel with live map integration is built into the portal for more functionality and a document and download panel is also made available.
Bridge management also forms part of the Integrated System with Bridge inspection and maintenance information included. This systems assists agencies to meet their objectives, such as building inventories and inspection databases, planning for maintenance, repair and rehabilitation interventions in a systematic way, optimising the allocation of financial resources and increasing the safety of bridge users.
