What Happens When Autonomous Technology Goes Wrong?
As autonomous vehicles become more commonplace and automakers invest millions into the development of such technologies, consumers and researchers alike are left to ponder the implications of such technology failing during operation.
The Mineta Transportation Institute published a new report, Analysis of Disengagements in Semi-Autonomous Vehicles: Drivers’ Takeover Performance and Operational Implications, which explores this case scenario.
The study looks at how humans interact with AV’s if it loses control while on the road. It measured how quickly and deliberately the car alerted drivers and how efficiently the driver could effectively react and take control.
The study tested 40 individuals starting at 18 years old to 55 years plus. Each driver was placed in a car simulator capable of handling both human and autonomous driving. The test measured response times and vehicle drift from a centerline under several different scenarios.
Key results showed that between two different speed settings (high speed of 65 mph and a low speed of 55 mph), the lower speed yielded better performance. Out of all the three different age groups tested, the older participants performed better in overall driving and driving after autonomous technology failure.
Researchers also found that individuals tended to increase their speed and steer after taking control of the vehicles, as opposed to braking. About half of the drivers also reported not seeing the visual warning on the central console but did hear the auditory warnings.
The report takes into consideration how AVs can affect roadways and drivers. It gives suggestions on what mobility and infrastructure changes may need to be implemented to ensure safety while operating autonomous technologies.

FLEET MANAGEMENT AUDIT
Fleet management is the use of a set of vehicles in order to provide services to a third-party, or to perform a task for our organization, in the most efficient and productive manner with a determined level of service and cost.
Fleet management activities are shown in the following graph 1:
Graph 1: fleet management activities
The proposal audit analyses and assesses all fleet management activities shown in the graph 1, and its main goals are:
- Know the overall status of the fleet management activities
- Provide the analysis, the assessment, the advice, the suggestions and the actions to take in order to cut costs and increase the efficiency and efficacy of the fleet management activities
With the information obtained, we’ll elaborate a report that holds the overall status of the fleet management as well as the suggestions, recommendations and the measures to take in order to cut costs and optimize the fleet management activities.
