Re: [sumo-user] TL Logic validation

[Jakob Erdmann <namdre.sumo@xxxxxxxxxxxxxx>]

Hello,

netconvert returns basically two types of signal plans depending on the edge priority values at an intersection

1) streams in opposite directions at the same time, seprate phase for exclusive left turns

2) every incoming edge gets its own phase where all turning directions get the green light

There are a lot more valid states and signal plans so feel free to design your own.

- You will receive a warning when loading a signal plan without yellow phase between the green and red phase.

- When you make your yellow phases to short (relative to road speed), you will see 'emergency braking" warnings from the simulation

- if you allow incompatible streams at the same time you may see collisions

regards,

Jakob

Dear SUMO,

A TL logic consists of concurrent phases that have a specific state
configuration. If you want to write a new TL how can you be sure that the
phases you specify are consistent to logic for example that a g follows y
follows r and that 2 lanes that share the same junction cant be green at
the same time?
The TL logics returned by netconvert are the only valid configurations of
states?

Thank you in advance,
Thanos Tasakos
