I deployed a traffic service on aws that uses a lambda function, but I have a hard time understanding how it works. For instance, I see that the lambda function contains .js files for traffic, but I don't understand what part I can edit to create proper requests for traffic flow based on geo-coordinates.
I found an article about geocoding app, but it felt a bit different from what I am trying to achieve. Which is to create a function just to retrieve the traffic flow information.
After you deploy the traffic application in lambda, you can retrieve the traffic info via the Lambda API gateway.
More details can be found in the below two online doc: https://github.com/heremaps/here-aws-sar/tree/master/serverlessFunctions/traffic

If you are looking for the rendered live-traffic map tiles, I would suggest using map tile application: https://github.com/heremaps/here-aws-sar/tree/master/serverlessFunctions/maptile
