Every now and then, few things come across my mind. At times, they are just thoughts in passing, but some of them are actually – well, at least I think so – workable ideas. I’ll display some of them below under CC BY-SA 3.0 Unported license.
- Smart traffic lights. The idea is simple: adjust the red light waiting time of each direction of an intersection according to how long the queue at each respective directions. A sensor – computer-vision enabled, perhaps – attached to a central computer should periodically calculate the appropriate waiting time.
- Crowdsourced-traffic reports. Hate being stuck in traffic? With GPS or GPS-enabled devices proliferating and digital maps of our beloved J-town abound, what’s missing here is a live traffic report. How about a subscription-based traffic report service for our GPS device that relies on user-submitted traffic report service? Set-up an SMS gateway, web-portal, and call-center as a receiving end for all the reports. Seed the service with official traffic reports from the Dishub – Indonesian DMV – and Polantas – traffic police – traffic centers and come up with a trust points scheme (based on how many corroborated reports you give to the service), I think this will work.
- Automated railroad crossing gates. Far too many accidents happen here in Indonesia at the railroad crossings. In most cases, it’s the driver’s fault – how hard can stopping be? But sometimes they happen because of negligence of the guard on duty and the fact that the crossing has no gates to begin with. I think the later reasons can be overcame with the use of automated gates. Sensors are put on the rails at a certain distance from the crossing. Based on their reading of the train’s speed and total length, the gates will automatically close accordingly.
