Yesterday Mumbai had a harrowing night with the downpour of 300 mm of rains in one day. Many office goers stayed back at their offices and others who braved the waterlogged streets to head home were helped by local residents and Ganpati mandals and gurudwaras and mosques, with offers of food/water and shelter. Each and every time, Mumbaikars respond to calamities, with a great display of collective humane behaviour that shows the city’s citizen resilience towards facing problems.
There are reports today of the good presence of the city police on the roads through the night and their work in keeping the traffic situation in control despite very slow movement of vehicles through waist deep waters at many places. The sensitivity and responsiveness of the Mumbai Police twitter handle during the entire ordeal was really good and has been much appreciated by the users.
What does this episode of natural disaster teach us to do better next time?
1. Mumbai has more than 4700 CCTV cameras across the city. Whatever are the informative images from these cameras could be linked to the Mumbai Police twitter handle so that situational information of what’s happening further up the road, is better communicated to the road users.
2. Electronic Board displays on roads could be increased in number substantially-again for better information dissemination.
3. Motorists typically rely on google maps to show them the fastest possible route to their destination. But in disaster times, such routes could be impassable. And they have no way of knowing that. Police can use GIS maps integrated with CCTV network as one very useful tool to periodically update and inform road users of the state of road and traffic conditions. A single map based view of the city with the ability to choose what geospecific information you want to see could be a great boon to the information hungry citizen stuck in a disaster situation. Currently, for the road users, there is no aggregation of the ground information on a map of the city. Further, traffic policemen can take photographs/videos of the traffic congestion at waterlogged sites on the roads not covered by CCTV cameras, thereby fixing lat-longs of such sites across the city on the map and giving a holistic view of the water logging and traffic congestion problem across the city. . Motorists and home goers viewing the state of road traffic on the map can then take informed decisions for travel. For the police on the road, this information can empower their man on the ground to take measures on the basis of the larger picture on the map to divert traffic away from waterlogged cul de sacs in his local area.
4. GIS map-based visual information on the Police website can additionally be used to display information on food/water/shelter sites across the city. Such information of voluntary efforts by citizens was seen to circulate on Whatsapp and Twitter last night. Aggregated information of these volunteer activities as well as the official arrangements, helps to reassure and keep calm despite a disaster situation. Electronic display boards could also display such information.
5. Hashtags for specific themes like traffic movement or voluntary aid in food/water/shelter can be used by police for collecting information and pictures from the public users of social media. This information could then be placed on the map for users to get information relevant to their needs. Such map based aggregation of information will also be very useful to the police control room to respond with useful guidance to distressed callers.
In disaster situations, people look to government for proper information and relief. And technology can provide that single point authentic source for coordinating an effective response.
