The good news is that Brake Safety Day, the Commercial Vehicle Safety Administration's unannounced inspection, which took place on May 3, 2017, found that 79% of the vehicles inspected had no major vehicle violations.
During the blitz more than 9,500 inspection were conducted — 8,140 in the U.S. and 1,384 in Canada.

Is a new, expanded role for adaptive cruise control systems on the horizon? A recent technical paper by engineers Zijia Zhong, Joyoung Lee and Liuhui Zhao at the Newark College of Engineering, New Jersey Institute of Technology, published by the Transportation Research Board suggests so.
According to the paper, titled "Multiobjective Optimization Framework for Cooperative Adaptive Cruise Control Vehicles in the Automated Vehicle Platooning Environment," cooperative adaptive cruise control has been proven in tests to be an effect means of automated longitudinal control technology with possible vehicle platooning applications in the near future.
The paper's authors have proposed an automated longitudinal control framework based on multiobjective optimization (MOOP) for CACC by taking into consideration four vehicle optimization onbjectives: mobility, safety, driver comfort, and fuel consumption.
The paper notes that of the target time headways that have been tested, the proposed CACC platoon control method achieved the best performance with 0.9- and 0.6-s target time headways. Compared with a non-optimization-based CACC, the MOOP CACC achieved 98%, 93%, 42%, and 33% objective value reductions of time headway deviation, unsafe condition, jitter, and instantaneous fuel consumption, respectively.
In comparison with a single-objective-optimization-based approach, which optimized only one of the four proposed objectives, it was shown that the MOOP-based CACC maintained a good balance between all of the objective functions and achieved Pareto optimality for the entire platoon.
