*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.
