DataCity
Smart-Mobility Living Lab in the center of a dense city. (New Brunswick)
SSM
Signal Status Message (V2X) sent by traffic signal controllers with info about the current status of lights (red, yellow, green, and the timing of signal changes)
SRM
Signal Request Message (V2X) sent by vehicles (usually emergency ones) request priority.
C-ITS
Cooperative - Intelligent Transport Systems
Well-known traffic simulators
SUMO, VISSIM, AIMSUN
Three main challenges of AV Testing
curse of dimensionality
cures of rarity
distribution shift
current safety critical event occurrence rate
10e-6
Distribution Shift
When short-term and small modeling errors accumulate both in space & time. Combine that with the following and you have distribution shift.
* Long time horizons
* highly interactive env where one actor behaving unrealistically will propagate to other actors as they react.
GAN
Generative Adversarial Network
Typically made up of a generator and discriminator. Discriminator: decide if the generation is real or fake.
PET
Widely used surrogate safety measure used to identify near-misses.
Post Encroachment Time. PET = Tb - Ta, where Tb is time b leaves the conflict area, and Ta is when a enters the area. A negative value is a collision, a small positive value is a near-miss.
A key paper and the foundation of many advances in NLP, LLMs, chatGPT, OpenAI, and BERT
“Attention Is All You Need” - Ashish Vaswani
This paper introduced the concept of the Transformer Model.
