Florida Autonomous Truck-Mount Attenuator (ATMA) – Demonstration and Evaluation

Project description

This project hosted a demonstration of the operation and function of the autonomous truck-mounted attenuator (ATMA) in a closed loop environment as well as in an active work zone.

Video

The research and funding agency were interested to understand the working of ATMA and observing individual plots such as speeds (leader and follower) vs time, one at a time, only provided limited information. I proposed to develop a animated videos collating all the information together which made it easy for the team to qualitatively understand the process and communicate with others. Below is a sample video create to cater the requirement (the video was create using R programming one year ago, since then my skills in R has improved tremendously)

The video collates various plots along with dashcam view, which makes it easy to qualitatively understand various aspects of the ATMA.

Subplots	Objectives
Dashcam video	Establishes ground truth – the video provides an opportunity for the analyst to visually inspect and correlate the traffic characteristics (speed, acceleration, etc.) with the data log retrieved from ATMA
GPS position of vehicles in road network	Provides location of vehicles (points) on primary road network (lines) for visual inspection. It helps to qualitatively understand the impact of road network elements such as intersection etc.
Time and status	Since several equipment are used in the data collection effort, this plot helps in reviewing the time component and the associated status of the follower ATMA. Info on different navigation status can be found in the final report.
Speed vs time and distance vs time plot	These plots quantify the instantaneous speed and distance traveled of leader and follower with respect to time.
