*Dummy nodes- *
In implementing a simple grid-like junction, is it necessary for later
versions of SUMO (0.18) to add dummy nodes at the ends of links/edges ?



*JTRROUTER - *
After referring to
http://sumo-sim.org/userdoc/Demand/Routing_by_Turn_Probabilities.html

I tried to generate route files like so ---->

*jtrrouter --turn-ratio-files=trial_one.turns.xml
--net-file=trial_one.net.xml --output-file=trial_one.rou.xml*

however, i am getting an error like this ---->


*Error: No route input specified.Quitting (on error).*

-- If i am not wrong, JTRRouter gives an output rou.xml file so what it
does it mean by this error?
--Also, i was wondering if i could instead write the routes explicitly
using python instead of adding probabilities to make the traffic movement
more realistic.




*One-to-many traffic light control*
It says in the documentation that

" In SUMO, a one-to-n dependency between signals and links is implemented,
this means each signal may control more than a single link - though
networks generated by NETCONVERT<http://sumo-sim.org/userdoc/NETCONVERT.html>or
NETGENERATE <http://sumo-sim.org/userdoc/NETGENERATE.html> usually use one
signal per link. "

I want to make sure that in a single junction having 4 lanes, each lane is
given a GREEN state and RED state in rotation.

 For example, Lane 1 is GREEN from 0s to 30s , others are all RED.
                     Lane 2 is GREEN from 31s to 45s, others are all RED.
                     Lane 3 is GREEN from 46s to 60s, others are all RED...
and so on.

So, i want to know if by saying type="traffic_light" at one junction, I'm
initialising only one traffic light for that junction or 4 traffic lights
for the 4 lanes?

If yes, how do I override NETCONVERT's default setting to have 4
disconnected traffic lights to operate at one junction instead of only one?

Your help is appreciated, thanks in advance.
