Last research group meeting of the semester at @UCBSafeTREC . It was a great opportunity to discuss our transportation safety projects in a constructive environment and to grow as researchers. Big thanks to @GrembekOffer for the mentorship and support.

Being part of @CSCRSinfo is one of the most rewarding parts of my job. I take pride in working together across universities led by @hsrcinfo to advance #safesystem using research, prof. development, and education. See our report below! roadsafety.unc.edu/wp-conten…
The 2023 #TRBAM ended today, though much of our staff came home yesterday (in some cases, pivoting travel modes to avoid flight disruptions). Great event, great interactions, great to be back in person! Sharing one more round of images showing off our busy week … 🧵

Had to force myself to come to #TRBAM this yr. I’m fond of my local work env & limited travel needs. But seeing how #SafeSystem approach has become focal for US traffic safety is worth the trip! I believe much was seeded by @USDOT-funded @CSCRSinfo. Come see 💪 work by this UTC

1/4 Can grandma deliver your groceries?
[I framed this comically since it’s not based on research we’re doing, but rather an insight from chats on the topic of safety and AV’s]
The main challenge of AV’s in achieving safety is the tradeoff between a SMOOTH ride and a SAFE ride.

3/4 users want a smooth & safe ride, but it’s not simple.
If your AV is moving people, delivering a smooth & safe ride is a hard problem to solve & will impose additional risks to VRU’s. But if your AV is moving goods, the ‘groceries’ wouldn’t mind being driven around by grandma

4/4 So, ideally efforts to test AV’s in urban environment should focus on delivering goods since it can more readily prioritize safety
Once we smooth the kinks of providing safety for non-occupants, we can tackle the challenge of also providing a safe & smooth ride for occupants

Given a crash between an SUV and a pedestrian, the ped is almost 87 times more vulnerable. US vehicle safety rating system provides information about the protective capability of vehicles to occupants but neglects to provide information about protection for vulnerable road-users

Ultimately, this is about the system's capability to control and/or contain the unsurvivable amounts of kinetic energy carried by motorized modes. If we don’t systematically monitor how well a vehicle can protect non-occupants, we are missing out on many life-saving innovations.

This also brings back some older work that quantifies the unbalanced safety consequences across different modes. It shows that pedestrians and bikes are many times more vulnerable given existing transportation mode-mix.

(1/5) This is a big one. @NSCsafety is reporting a spike in traffic fatality rates which echoes what we've been seeing on CA highways (tims.berkeley.edu/covid19.ph…). This really demonstrates the importance of kinetic energy as a focal traffic safety variable.

(4/5) During the pandemic people still make mistakes which can result in crashes. The main difference during the pandemic is derived from the fact that the average trip is faster, and accordingly carries more kinetic energy, so the consequences of a crash are more severe.

(5/5) Bottom line: the transportation system suddenly has to deal with an even higher proportion of severe crashes than before (aka higher average kinetic energy). This increased burden is creating the catastrophic spike we're seeing in U.S. traffic fatality rates.
