A middleware protocol for time-critical wireless communication of large data samples

We present a middleware-based protocol that reliably synchronizes large samples consisting of multiple frames efficiently and within application level QoS requirements over a lossy wireless channel. The protocol uses a custom retransmission scheme, exploiting the latency requirements on sample level for frame level scheduling. It can be integrated into the popular DDS middleware. We investigate some technical limits of such a protocol and compare it to existing error protocols in the software stack and in the wireless protocol and combinations thereof. The comparison is based on an Omnet++ simulation using an established wireless channel error model. For evaluation, we take a use case from automated valet parking where infrastructure data provided via a wireless link augments in-vehicle sensor data. The use case respects the related safety requirements. Results show that the application awareness of the presented protocol, significantly improves service availability by transmitting data efficiently in time even under higher frame error rates

Urban Scaffold for Renewing Derelict Fabric

In a historic Italian town, opportune innovations in automated parking provide solutions to multifaceted challenges in urban renewal and economic revitalization. A single automated parking facility alleviates pressure in urban infrastructure, simultaneously stabilizing an endangered building shell, and becoming a catalyst for phased urban redevelopment. Strategic opportunities in geography and context are pursued to produce upfront and long-term project feasibility

Interstate 380 Planning Study(PEL): Automated Corridor, July 2018

The Iowa Department of Transportation (Iowa DOT) is conducting a planning study of the Interstate 380 (I-380) corridor between the Iowa City and Cedar Rapids metropolitan areas to best address safety and mobility needs of all freight and passenger travelers. This study is being conducted using the federally adopted Planning and Environmental Linkage (PEL) Study process. It will allow near-term improvements to be planned, designed, and as funding is available, constructed in accordance with the long-term plan. As part of the Planning Study, an Automated Corridor study was conducted

Comparison of safety and kinematic patterns of automated vehicles turning left in interaction with oncoming manually driven vehicles

Highly and fully automated driving has been under devel-opment for the past two decades in order to increase comfort, efficiency, and traffic safety. Particularly in the latter domain, experts agree on automated driving, especially in case of automated vehicles (AV) with SAE level 4 or higher, having the most promising effects. Automated driving is expected to decrease the number of seriously injured or even killed road users to zero (Vision Zero). However, automated driving is still in an early stage of development and many AV tend to drive very carefully to avoid crashes. So, the goal is to make driving more efficient while maintaining the highest level of safety. In the project “Digitaler Knoten 4.0” cooperative automated driving was assessed regarding ef-ficiency and safety aspects. One of the use cases investigated was turn-ing left with oncoming traffic at an urban intersection as this situation represents one of the most complex situations in urban areas yielding to crashes with—in many cases—serious consequences for the involved road users. At the Application Platform Intelligent Mobility (AIM) Re-search Intersection in Braunschweig, Germany, an SAE level 3 AV was turning left interacting with oncoming manually driven vehicles (MV). The performance of the AV was compared to MV executing the same manoeuvre. The recorded video-based trajectories of the respective AV as well as MV were analysed regarding the influence of situational factors (e.g. position of the vehicle in the queue and gap acceptance) and kinematic factors (e.g. speed and acceleration) on traffic safety. The similarities and differences between this specific AV and MV were identified yielding insight for further developing algorithms for more efficient driving while maintaining the same traffic safety level. For instance, it appears that the AV shows a very conservative left turn-ing behaviour leading to very safe PET distributions in comparison to left turning MV

AVENUE21. Connected and Automated Driving: Prospects for Urban Europe

This open access publication examines the impact of connected and automated vehicles on the European city and the conditions that can enable this technology to make a positive contribution to urban development. The authors argue for two theses that have thus far received little attention in scientific discourse: as connected and automated vehicles will not be ready for use in all parts of the city for a long time, previously assumed effects – from traffic safety to traffic performance as well as spatial effects – will need to be re-evaluated. To ensure this technology has a positive impact on the mobility of the future, transport and settlement policy regulations must be adapted and further developed. Established territorial, institutional and organizational boundaries must be investigated and challenged quickly. Despite – or, indeed, because of – the many uncertainties, we find ourselves at the beginning of a new design phase, not only in terms of technology development, but also regarding politics, urban planning, administration and civil society

Connected And Autonomous Vehicles: Implications For Policy And Practice In City And Transportation Planning

Vehicular transportation is undergoing a technological change. Cars are being automated, which have significant implications for governments. Autonomous Vehicles (AVs) and Connected and Autonomous Vehicles (CAVs) can have significant benefits such as improved overall roadside safety and efficiency however, there may also be negative effects as well such as increased sprawl and social inequity. In Ontario, AV testing on public roads has been conducted under O. Reg. 306/15, which has also helped to establish Ontario as a leader of innovation in Canada. Before CAVs can be mass deployed in Ontario and Canada at large however, a number of barriers will need to be addressed such as legislation, infrastructure and cooperation between municipalities, and between municipalities and the automotive industry. Recommendations for municipal and provincial governments are provided

Automated Transit Networks (ATN): A Review of the State of the Industry and Prospects for the Future, MTI Report 12-31

The concept of Automated Transit Networks (ATN) - in which fully automated vehicles on exclusive, grade-separated guideways provide on-demand, primarily non-stop, origin-to-destination service over an area network – has been around since the 1950s. However, only a few systems are in current operation around the world. ATN does not appear “on the radar” of urban planners, transit professionals, or policy makers when it comes to designing solutions for current transit problems in urban areas. This study explains ATN technology, setting it in the larger context of Automated Guideway Transit (AGT); looks at the current status of ATN suppliers, the status of the ATN industry, and the prospects of a U.S.-based ATN industry; summarizes and organizes proceedings from the seven Podcar City conferences that have been held since 2006; documents the U.S./Sweden Memorandum of Understanding on Sustainable Transport; discusses how ATN could expand the coverage of existing transit systems; explains the opportunities and challenges in planning and funding ATN systems and approaches for procuring ATN systems; and concludes with a summary of the existing challenges and opportunities for ATN technology. The study is intended to be an informative tool for planners, urban designers, and those involved in public policy, especially for urban transit, to provide a reference for history and background on ATN, and to use for policy development and research
