Current features

• Add/Remove traffic lights
• Adaptive timed traffic lights
• Add priority signs
• Change lane arrows
• Connect individual lanes with each other
• Add/Remove crosswalks
• Manually control traffic lights
• Timed traffic lights
• Clear traffic
• No despawn

Todo list

• I would like to investigate why yellow traffic lights sometimes are not properly rendered.
• I would like to implement traffic light templates so that you would not need to manually set up individual steps for common junction patterns.
• Stop signs should be more useful. Drivers should act more realistically/confident when stop/yield signs and traffic jams meet together.
• Adaptive Timed Traffic Lights: Currently only vehicles on the road segment next to the junction are being measured. I would like to expand the traffic measurement to 2 segments.
• When switching between control modes, the UI starts to ignore user mouse input. This is annoying. I will hopefully fix that.
• We could measure if there is traffic backing up after a timed traffic light. If it is the case (that is: cars having a green light do not move) the next timed step could be activated.
• There are still some issues with crossings and pedestrain crossing lights (missing textures, double crosswalks). Let's see what can be done.
• For new users it takes some time to understand how the mod works. Having something like a (video) manual would be great. Or just a better UI.

Upcoming changes

• Code optimization & refactoring
• Timed Traffic Light Templates (ready-to-use directional traffic light patterns)
