Making Infrastructure Fit for Automated Driving

2018

Does automated driving need any infrastructure (adjustment) at all? Is this discussion rather car manufacturers'<br> and telematics industry's proactive market development? Will Europe risk its strategic technological strength in<br> transport management by trying to learn abroad? A joint effort in cross-industry research and development has<br> brought significant achievements in the field of connected driving in Europe. In this paper we evaluate recent<br> achievements in connected driving and outline next-level challenges in bringing connected driving and automated<br> driving to metropolitan areas. Based upon our lessons learnt and our assessment of what is being achieved in<br> similar activities, the paper gives a flavour of what makes infrastructure fit for automated driving in mixed-traffic<br> situations in urban areas. The paper presents an implementation and deployment approach to Intersection Safety<br> for the urba...

Towards Road Safety in LMICs: Vehicles that Guide Drivers on Self-Explaining Roads

2020

Traffic collisions cause a huge problem of public health in low and middle income countries.. The safe system approach is generally considered as the leading concept on the way to road safety. Based on the fundamental premise that humans make mistakes, the overall traffic system should be ‘forgiving’. Sustainable safe road design is one of the key elements of the safe system approach. However, the road design principles behind the safe system approach are certainly not leading in today’s infrastructure developments in most LMICs. Cities are getting larger and road networks are expanding. In many cases, existing through-roads in local communities are up-graded, resulting in heavy traffic loads and high speeds on places, that are absolutely not suited for this kind of through-traffic. Furthermore a safe system would require that functional design properties of cars and roads would be conceptually integrated, which is not the case at all. Although advanced driver assistance systems are...

Trustworthy Automated Driving through Increased Predictability: A Field-Test for Integrating Road Infrastructure, Vehicle, and the Human Driver

Transportation Research Procedia, 2023

Higher levels of Automated driving (AD) vehicles require new allocations of functions among drivers, vehicles, and road infrastructure. The European Horizon 2020 project HADRIAN investigates how such reallocations could be practically achieved as part of Collaborative Connected and Automated Mobility (CCAM) to meet the benefit expectations of drivers while increasing safety. In a field demonstration it is shown how road infrastructure can be used to expand the prediction horizon of AD vehicles and how multimodal, driver-state dependent human machine interactions (HMI) could help address European mobility needs with AD vehicles and increase operational acceptance and safety. Whereas performance results of the various innovations are reported elsewhere, in this paper the evaluation of the feasibility of the HADRIAN innovation in an open road field-demonstration is described.

From Automated Highways to Urban Challenges

Abstract— This paper describes autonomous vehicle and driver assistance research beginning with the 1997 National Automated Highway System Consortium Demonstration. As a microcosm of the community at large we discuss how Carnegie Mellon autonomous vehicle research has progressed in the last decade. Since the demonstration we have formed two companies: AssistWare became a leading developer of lane departure warning systems; and, Applied Perception which emphasized off-road navigation and perception research. In parallel, we have competed in the DARPA Grand Challenges and won the Urban Challenge. Each of these endeavors has deepened our understanding of what it will take to broadly deploy autonomous vehicles.

Road Infrastructure Challenges Faced by Automated Driving: A Review

Applied Sciences

Automated driving can no longer be referred to as hype or science fiction but rather a technology that has been gradually introduced to the market. The recent activities of regulatory bodies and the market penetration of automated driving systems (ADS) demonstrate that society is exhibiting increasing interest in this field and gradually accepting new methods of transport. Automated driving, however, does not depend solely on the advances of onboard sensor technology or artificial intelligence (AI). One of the essential factors in achieving trust and safety in automated driving is road infrastructure, which requires careful consideration. Historically, the development of road infrastructure has been guided by human perception, but today we are at a turning point at which this perspective is not sufficient. In this study, we review the limitations and advances made in the state of the art of automated driving technology with respect to road infrastructure in order to identify gaps th...

ScienceDirect Advanced Driver Assistance System for road environments to improve safety and efficiency

The advances in Information Technologies have led to more complex road safety applications. These systems provide multiple possibilities for improving road transport. The integrated system that this paper presents deals with two aspects that have been identified as key topics: safety and efficiency. To this end, the development and implementation of an integrated advanced driver assistance system (ADAS) for rural and intercity environments is proposed. The system focuses mainly on single-carriageways roads, given the complexity of these environments compared to motorways and the high number of severe and fatal accidents on them. The proposed system is based on advanced perception techniques, vehicle automation and communications between vehicles (V2V) and with the infrastructure (V2I). Sensor fusion architecture based on computer vision and laser scanner technologies are developed. It allows real time detection and classification of obstacles, and the identification of potential risks. The driver receives this information and some warnings generated by the system. In case, he does not react in a proper way, the vehicle could perform autonomous actions (both on speed control or steering maneuvers) to improve safety and/or efficiency. Furthermore, a multimodal V2V and V2I communication system, based on GeoNetworking, facilitates the flow of information between vehicles and assists in the detection and information broadcasting processes. All this, combined with vehicle positioning, detailed digital maps and advanced map-matching algorithms, establish the decision algorithms of different ADAS systems. The applications developed include: adaptive cruise control with consumption optimization, overtaking assistance system in single-carriageways roads that takes into account appropriate speed evolution and identifies most suitable road stretches for the 2246 Felipe Jiménez et al. / Transportation Research Procedia 14 (2016) 2245-2254 maneuver; assistance system in intersections with speed control during approximation maneuvers, and collision avoidance system with the possibility of evasive maneuvers. To this end, mathematical vehicle dynamics models have been used to ensure the stability, and propulsion system models are used to establish efficient patterns, Artificial Intelligence and simulation are used for experimentation and evaluation of algorithms to be implemented in the control unit. Finally, the system is designed to warn the driver if a risk is detected and, if necessary, to take control of the vehicle. The system has been implemented on a passenger car and has been tested in specific scenarios on a test track with satisfactory results.

This report identifies how two core elements of the road infrastructure, road markings and traffic signs, need to be adapted to optimise the effectiveness of Advanced Driver Assistance Systems (ADAS) in vehicles, in particular Lane Departure Warning (LDW ), Lane Keeping Assistance (LKA) and Traffic Sign Recognition (TSR ) (Box 1).
