crossing_signal

Pedestrian crossing signal for tram

Var Details

amber_distance_threshold

• Proximity thresholds for crossing signal states

  • The proc that checks the distance between the tram and crossing signal uses these vars to determine the distance between tram and signal to change

  • colors. The numbers are specifically set for Tramstation. If we get another map with crossing signals we'll have to probably subtype it or something.

  • If the value is set too high, it will cause the lights to turn red when the tram arrives at another station. You want to optimize the amount of

  • warning without turning it red unnessecarily.

  • Red: decent chance of getting hit, but if you're quick it's a decent gamble.

  • Amber: slow people may be in danger.
