Re: [sumo-devel] Feature wish - TraCI and traffic lights

Hi,
just some questions before I open the ticket (which does not mean it
will be processed soon ;-))

If you have the id of the next traffic light and the index of the link
the vehicle will use when passing the relevant junction, I think you
can already extract that info with current TraCI (by extracting the
complete program and the index of the current phase). So will a
function returning the next tls id and link id suffice or do you need
the shortcuts for performance (or other) reasons? Furthermore I think
you will need the next color as well because it may ambiguous if the
current color is yellow (if you don't extract it from the program by
yourself).
