Safety

This paper analyses typical intersection scenarios with respect to the feasibility of
motorbike-based warning or automatically intervening assistance systems to protect the
motorbike driver from dangerous situations induced by surrounding car drivers. Based on
accident statistics, typical crash scenarios have been identified. The trajectories of the
involved vehicles have been modelled realistically, and the resulting scenarios have been
analyzed in a simulation environment with respect to a variety of parameters. The potential
of motorbike-based assistance systems is assessed, and sensor and environment perception
requirements are derived.

The Mn/DOT Connected Vehicle Road User Fee Test (MRFT) is an extensive demonstration project undertaken in parallel with other Connected Vehicle Programs.  Mn/DOT’s efforts include designing, building, and testing three new software applications that combine safety and mobility applications from the Connected Vehicle world with a mileage-based user fee application from the road user pricing world. The combination of these different types of applications causes challenges in balancing the need for detailed information to support safety and mobility needs with protecting the privacy of the traveling public.  A unique solution to this dilemma has been developed and will be tested through the demonstration.  This presentation will provide a background of the conflicting needs of Connected Vehicle versus MBUF applications and will summarize the solution being implemented in Minnesota.

1-DIN aftermarket equipment for in-vehicle use has special challenges from the human machine interface (HMI) perspective. Development and sales of these systems is usually driven by cost. The face plate is limited in space. Displays are limited in size. The user group is very inhomogeneous. Competition between producers is hard, at stores aftermarket devices are presented parallel, so users choice will be influenced by the price and “at first sight”- attractivity. After all, the HMI design has to match safety criteria. The use of the systems on the road should be non-distractive, safe, fast, and easy. On the other side, additional functions beside traditional audio subsystems, like telephone, WAP applications, or navigation become more and more part of 1-DIN aftermarket devices. Latest systems are scalable, meaning, the user may add subsystems, following his own needs. In a study with 35 subjects, representing traditional user groups in age and gender, different versions of faceplates were rated. Results show smaller differences in human factors oriented items (readability, color coding, display size) but clear differences on the emotional side (“I like it”, “I would love to own it”, …). An expert-analysis of existing systems lead to the following suggestions: reduction of number of buttons, upsizing the display, allowing direct access to main functions, creating a flat menu tree, or using status information to keep the user up with information on were certain functions are etc. The graphic design of the system should meet the taste and the expectations of the targeted users. On basis of the study and the analysis solutions were developed.

Rapidly developing economy evoked the increasing number of vehicles, and the urban traffic is already
overburdened. Nowadays if we cannot rapidly dispose the emergencies, such as traffic accident, vehicle
breaking, illegal driving and bad weather conditions, the traffic congestion will be diffused quickly, and
sometimes even worse to lead the local traffic paralysis. As to the emergencies have some
characteristics of the frequentness and uncertainty on time and space. It is a desirable problem
to solve among the major cities nation-wide that how to enhance the rapid response capability
to these emergencies, where the traffic policemen should appear immediately when they are
needed, how to avoid the diffusing of the traffic congestion and the traffic paralysis, etc.
Therefore we’ll introduce you the functions and characteristics of the Rapid Responding and
Disposing System of Road Traffic Emergency developed and used in the city of Dalian, China.
The followings are some details such as finding and disposing the road traffic congestion
rapidly, establishing and implementing the per-plans for special safekeeping assignments,
monitoring the illegal vehicles and traffics, real time traffic information transferring, and the
evaluating of the on duty policemen’s work.

This paper presents the methods and findings of a study focused on the preliminary development of a driver-vehicle interface (DVI) for a transit bus frontal and side collision avoidance system (CAS). A transit bus CAS is expected to function as a copilot, observing bus actions and intervening with various warnings and/or exerting a temporary, controlling function to avoid an otherwise imminent collision. The overall approach to the project involved tapping the expertise and experience of transit bus driving instructors and operators, and drawing on past passenger and commercial vehicle collision warning and avoidance system (CW/AS) research. Using these two sources of information, the transit bus operating environment was characterized. Then, preliminary CAS system requirements and functions were identified. Based on an understanding of the transit bus environment and CAS functionality, an initial set of transit bus CAS DVI display concepts was generated. A focus group with transit bus operators was conducted to review the initial display concepts. Based on focus group participant feedback, a final set of preliminary transit bus CAS DVI concepts was generated. Lastly, recommendations for future human factors testing and evaluation of the preliminary display concepts are proposed.
