GIS and Fiji Roads Authority
by Nemaia Koto
The Fiji Roads Authority (FRA) is essentially an asset management agency that looks after the roads, jetty’s, bridges and streetlights inventory. Using GIS technology, more specifically through ArcGIS Enterprise platform, the FRA manages these assets through their online web portal: https://gis.fijiroads.org/arcgis/home/. This portal not only displays the asset inventory for the FRA, but also provides data services for use in desktop GIS (ArcGIS Desktop, MapInfo, QGIS, RAMM GIS, AutoCAD) or other applications using the ArcGIS API. Additionally, map services (WMS) can be viewed and queried, and feature services (WFS) can be exported for off-line use.
Using the platforms mapping and analytics tools, the FRA has a Web based GIS infrastructure that can be accessed by anyone on any device, anywhere at any given time.
This paper will seek to briefly discuss the development of the ‘Road Accidents’ webmap and how GIS developed a blackspot map showing clusters of road accidents.
Developing the Road Accident Database and WebMap
1. Road Accident Data: The Traffic Unit within the Fiji Police Force collects all road accidents data and inputs the information on their IMAP database. Through collaborative efforts between the Fiji Police and FRA the GIS team exports these raw data from their database.
2. Data Recoding and Cleaning: In its raw form, the database represents encoded values for each variable, and for this step, all the variables are coded accordingly, at the same time cleaning the database of incorrectly inputted data.
3. Web Map Application: This database is then geocoded on ArcGIS Pro and creating a web service, it is then published on the FRA online platform. The image below shows a heat map of the final product showing where accident back spot is more likely.
Future Possibility and Summary:
The identification of these black spot areas provides a chance for the FRA to identify and implement changes by constructing and implementing road furniture such as road safety signs, roadside barriers and possibly realigning section of road that could potentially minimize road accidents and improve the overall safety within the road network. This will go hand in hand with the government initiative coined ‘Fiji Decade of Action for Road Safety 2011-2020.
In summary, this is one of the many applications of GIS within the Fiji Roads Authority. However, with this particular exercise it can be stated that with inter government agency co-operating, and with the use of advanced geospatial technology, the aim of minimizing road accident is simply a click away.
