Successful

success, second attempt 28.07.2020_17:06:16_11_ckpt=07850_scenario=NGSIM_LANE_CHANGE_I80_VALIDATION_steps=37_total-reward=1.9.avi

Had to retreat and go again

(the agent as usual: tries to execute maneuver immediately)

success, speedy 28.07.2020_17:06:16_14_ckpt=07850_scenario=NGSIM_LANE_CHANGE_US101_VALIDATION_steps=21_total-reward=1.9.avi

High speed

(human would do this more smooth)

Failed

failed, cut in 28.07.2020_17:06:16_6_ckpt=07850_scenario=NGSIM_LANE_CHANGE_US101_VALIDATION_steps=17_total-reward=-0.30000000000000004.avi

Cut-in, car showed up on the right lane

(not enough time to retreat, should've speed up before)

failed, cut in 28.07.2020_17:06:16_11_ckpt=07850_scenario=NGSIM_LANE_CHANGE_US101_VALIDATION_steps=8_total-reward=-0.6.avi

Another cut-in

openDD

Successful

success, smooth & safely 28.07.2020_15:12:53_9_ckpt=10100_scenario=OPENDD_RDB1_DENSE_steps=127_total-reward=2.0.avi

Smooth steering, safe acceleration

(speed-up at exit as usual)

success, yields to human driver 28.07.2020_15:12:53_5_ckpt=10100_scenario=OPENDD_RDB4_DENSE_steps=130_total-reward=2.0.avi

Yields to human entering the roundabout

(reasonable decision for this edge case)

Failed

failed, didnt care about other car 28.07.2020_15:12:53_8_ckpt=10100_scenario=OPENDD_RDB4_DENSE_steps=29_total-reward=-0.7.avi

Ignoring a car (enforcement of priority)

(very common case, too weak acceleration)

failed, unusal situation 28.07.2020_15:12:53_9_ckpt=10100_scenario=OPENDD_RDB2_DENSE_steps=80_total-reward=-0.1.avi

Hitting a car on merge

(unusual situation, specific for this map)
