In preparation for ERP 2.0, I recently changed my IU to the new OBU, but opted out of the touchscreen installation. LTA provides an option to download their ERP 2.0 app, which is supposed to function like the OBU screen to some extent. It includes functions like ability to view ERP charging details, traffic alerts, and manage payment options via your smartphone.
The ERP 2.0 app only runs in landscape mode and requires pairing with the OBU.
The app displays pretty much the same info as the physical touchscreen, which I thought is quite basic. I understand the need to not distract drivers with too much info, but surely it can provide more useful content than function as a glorified digital clock?
As I had a bit of time on a Saturday afternoon I decided to see what I can prototype using v0.dev, the AI-powered tool from Vercel. This is my first time using v0.dev and this is the result:
You can play around with the live app deployed to Vercel. This was done entirely in v0.dev in an hour with default settings with the free plan. It even works in portrait mode 🙂
You can see how I build the app by looking at the chat log. The app pretty much works without errors in each generation step. This is definitely a more polished way to develop quick frontend prototypes, compared to the early days of copy-pasting code, and asking it to make fixes.
Having said that, I do have to give quite specific instructions at some point to guide the model to make changes in the exact way that I want, for example to get the progress ring to start at the bottom instead of the top.
You can start building in Vercel for free, with USD5 of monthly credits. The app that I created cost me USD0.62. So I still have enough credit to play around before it runs out.
