Jakarta Smart City’s Data & Analytics division has worked with government agencies to establish 60 visualizations that help address issues like pollution, traffic, and flooding. In the case of pollution and traffic, these issues are closely linked and the division first used Tableau to understand the extent of pollution based on information collected from sensors placed around Jakarta.
This data ultimately helped inform a policy that limits the number of vehicles permitted to travel into the city each day. Known as the ‘odd-even’ policy, it restricts certain roads to vehicles on certain days based on the last digit of their registration plate. The policy is intended to encourage public transport and the city continues to monitor its effectiveness by analyzing whether there are increases in public transport use or whether traffic jams are forming in new areas. This data will help to refine the policy as needed and make any necessary adjustments to public transport.
To address flooding in the city, the Data & Analytics team has set up Tableau dashboards for real-time monitoring of river and sea levels. If the water reaches a certain point, it triggers an alert that initiates a quick response from the government. Also, by analyzing and visualizing the water levels over time, the city can better understand why and when the flooding occurs and take action to manage risk.
Juan Kanggrawan, Head of Data Analytics at Jakarta Smart City, said that in addition to helping solve these and other challenges, Tableau had helped to foster a healthy culture of open data sharing. This is evident not only internally but through Jakarta’s open data project which provides public access to 40 visualizations.
