Safety

To deter dangerous driving, we recently proposed a safe driving promotion system, which displays real-time driving scores and rankings to drivers. Thus, it is reasonable that our system will rouse a competitive spirit, which will improve driving behavior. In this study, the effect measurement of our system was carried out using a driving simulator. Time gaps, the frequency of sudden deceleration, and the number of lane changes were compared using four conditions: control, slogan, warning, and competition conditions. The results of the experiment suggest that the competition condition, which simulated our proposal, most effectively deters dangerous driving.

Communication based driver assistance systems of the future are supposed to inform the
driver about dangerous road and traffic conditions. This paper investigates the technology
potential of the Universal Mobile Telecommunications System (UMTS) for realizing
delay critical hazard warning services. First, an overview of the radio network
capabilities for early UMTS standard releases as well as for recently added features such
as the High Speed Packet Access (HSPA) are  provided. The analysis of the features
focuses on the delays for both uplink message collection and downlink message
distribution. Exemplary delay measurements in a live network are presented. Furthermore,
the potential of the Multimedia Broadcast Multicast Service (MBMS) with resource
efficient point-to-multipoint transmission to large user groups is analyzed. Finally, the
relationship between delay performance and network resource consumption required for a
hazard warning service is discussed and a concept proposal is given.

A new safety application, as part of ITS Advanced Rural Transportation System (ARTS), has been developed and deployed on a two-lane rural road (Route 114) in Southwest Virginia. The route has a rolling geometry of several vertical curves and is subject to significant head-on accidents. During the period 1994-2000, the road experienced 11 crashes that resulted in 12 fatalities and 29 injuries. All these accidents were a result of two main conditions:

1- Illegal passing maneuvers crossing solid yellow centerline, and

2- A short passing sight distance due to the road vertical profile.

Accidents reports indicated alcohol involvement in some of these incidents.

The main objective of the research, supported by Virginia Department of Transportation VDOT, is to design, install, test and evaluate a video detection-based warning system by installing an efficient system on one vertical crest curve on Route 114, capable of performing the following two main functions:

1. Detect vehicles that attempt to violate the no-passing zone.

2. Warn the violating drivers in order to discourage them from continuing their risky

maneuvers.

The U.S Government and the automotive industry have developed and tested prototype systems to evaluate the effectiveness of using Dedicated Short Range Communications (DSRC) for vehicle safety and non-safety applications. While initial test results have indicated promise for these systems, benefits for cooperative vehicle safety applications are proportional to the number of vehicles equipped. Systems tested to date have used expensive, high-performance, “fully embedded” architectures to prove these systems are technically feasible. To expedite reaching installed equipment penetration levels necessary to provide visible collision avoidance benefits to drivers on a regular basis, viable deployment scenarios include options for retrofit or aftermarket devices for equipping the existing vehicle fleet. This paper provides test results comparing currently used and more cost-effective methods of obtaining accurate and timely dynamic vehicle information (i.e., yaw rate and longitudinal acceleration).
