An adaptive peer-to-peer collision warning system

Abstract

Absfrucf-Cooperative vehicle collision warning system is made possible by recent progress in advanced positioning systems and wireless communication technology. In this paper we report our work in developing a cooperative intersection collision waming system that is not limited by the requirement of line-of-sight. The novel elements of the system include the use of a dynamic ad hoc wireless network for peer-to-peer data sharing, a new intersection collision warning algorithm, and a flexible and extensible software architecture and system design. The very same system is also capable of collision warning for other scenarios such as frontal and rear-end. Further, the tunable parameters in the algorithm make it possible for the system to adapt to the preference and capability of each individual driver.

Road Intersections as Pervasive Computing Environments: Towards a Multiagent Real-Time Collision Warning System

“…If collision is detected, it is important to realise whether the time and distance needed to respond to the warning and avoid the collision is sufficient [2]. Time-To-Collision (TTC) is computed by the pair-wise collision detection algorithm [2].…”

“…Therefore, the complex nature of intersection collisions requires systems that warn drivers about possible collisions. In addition, given the uniqueness of each intersection, rather than manually finetuning a system for each intersection, an intelligent system for intersection safety should be able to adapt to different types of intersections automatically [2,3] are still infrastructure-only systems, and are limited in many factors, mainly due to inexistence of communication between road infrastructure and vehicles and inability of the systems to adapt to different types of intersections. Vehicle-based intersection collision warning systems are fairly effective for a single vehicle as there's no any communication means between vehicle and infrastructure.…”

“…Intersection collision warning and avoidance systems can be categorized as either vehicle-based, infrastructure-only or as infrastructure-vehicle cooperative [1]. Many existing intersection collision warning systems [2,3] are still infrastructure-only systems, and are limited in many factors, mainly due to inexistence of communication between road infrastructure and vehicles and inability of the systems to adapt to different types of intersections. Vehicle-based intersection collision warning systems are fairly effective for a single vehicle as there's no any communication means between vehicle and infrastructure.…”

“…A number of systems have been designed specifically with traffic safety applications in mind [18,8]. [32] studies safety applications in the context of DSRC.…”

Context-Aware Ubiquitous Data Mining Based Agent Model for Intersection Safety

“…Data mining is the development of methods and techniques to gain knowledge from data by pattern discovery and extraction [4]. Data analysis techniques are necessary for processing information both on roadside and in vehicle situations [16]. However, data mining and machine learning techniques require high computational resources as knowledge is discovered from the analysis of huge data storages.…”
