Using scaled down testing to improve full scale intelligent transportation

Abstract

This study illustrates a methodology to reduce the time and effort spent on full-scale Intelligent Transportation System testing, through the use of small-scale testbeds. Scaled down testing platforms enable the researchers to implement, compare, and assess different architectures for intelligent transportation by deploying hardware-in-the-loop (HIL) simulation and testing, giving strong indications on the performance and high-level behavior of such systems at full scale. The performance of the scaled down testing is illustrated using a specific example based on an autonomous parking. The approach is demonstrated on intelligent transportation system testbed in The Ohio State University Control and Intelligent Transportation Research Laboratory. The detailed experimental results show the applicability and robustness of the proposed system.

Automatic Generation of Safety-Critical Test Scenarios for Collision Avoidance of Road Vehicles

“…While efforts with physical test fleets are steadily increased [3]- [5], it is obvious that physical tests alone are too costly and time consuming. For prototyping new ideas more quickly, scaled-down vehicles are sometimes used [6], [7]. The main direction taken by industry and academia, however, is to accompany physical tests with virtual driving tests, requiring the development of a simulation environment in which vehicles can be tested by many factors faster than in real-time, in order to expose the vehicle under test-in this work referred to as the ego vehicle-to many different situations, see e.g., [8]- [10].…”

Design, Implementation, and Configuration of Laser Systems for Vehicle Detection and Classification in Real Time

“…The choice between the commercial units offered today in the market has been made based on their presence in current ITS systems and in the bibliography. Thus, three of the equipment most used by different authors [22][23][24][25] and a multisensor system were selected for analysis. To standardize this system and facilitate the future implementation of this technology in the road sector, a series of technical specifications have been established:…”
