Use serverless here-api in lambda to extract traffic flow

Question

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.

Answer 1

After you deploy the traffic application in lambda, you can retrieve the traffic info via the Lambda API gateway.

• https://.execute-api..amazonaws.com/Prod/traffic/api/traffic/
• https://.execute-api..amazonaws.com/Prod/traffic/api/traffic.maps/

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
