Safety

Certification is commonly required for safety related applications, including those dealing
with localization. With the upcoming European satellite based localization system, the need
arises for the safety related certification of the corresponding applications and devices. The
existence of standards is mandatory for this sort of certification. For economic reasons, it
seems sensible to share knowledge and determine the application of standards across various
domains (e.g. different forms of transportation such as railways, avionics, maritime and road
transportation). To improve the tangibility of such documents, the application and utilization
of formal specifications and descriptions can help the communication process between
various stakeholders.

As an example of the newly established ITS Archive Data User Service (ADUS), this study utilizes information technologies to archive incident data collected by NAVIGATOR, Georgia’s ITS system, which makes it feasible to incorporate sophisticated speed contour and incident mappings to unveil the possible causal factors of secondary accidents. This study brought out a new definition of secondary accidents: an accident is a secondary accident if it falls in the congested contour area caused by the initial incident. Preliminary findings in this study demonstrated the suitability and usability of such a definition. State Department of Transportation and local transportation agencies could exploit the possible benefit of eliminating all the secondary accidents to enhance the support for the deployment of Intelligent Transportation System.

Arizona  DOT  and  Maricopa  County  DOT  have  recently  launched  the  Arizona  E-
VII program.  This paper outlines the goals, scope, and current activities under this
technology development and testing program.  This program is focused on rapidly
developing  and  deploying  real-world,  high-impact  systems  aimed  at  improving
safety,  mobility,  emergency  response,  and  travel  time  reliability  for  public  safety
applications.

The Advanced Crash Avoidance Technologies (ACAT) program will develop a Safety Impact Methodology (SIM) tool with the capability to assess benefits of vehicle crash avoidance technologies.  Four project teams were selected to develop a SIM to assess safety benefits of the following technologies: Advanced Collision Mitigation Braking System; Lane Departure Warning Technologies; Backing Crash Countermeasures; and Forward Pre-Collision Safety Systems.  Safety impact assessment for these vehicle crash avoidance systems will utilize a combination of national crash databases; data gathered from previous projects, data that will be collected from test track and driving simulator experiments, and data that will be generated from computer simulation.

This paper will discuss the Automatic Incident Detection (AID) system along the I-95 corridor in the Philadelphia area, the first of its kind in this region. The paper specifically focuses on data errors and error sources, and presents findings of the data analysis. The AID system is expected to greatly enhance the Pennsylvania Department of Transportation, Engineering District 6-0’s (PENNDOT 6-0’s) Traffic Control Center (TCC) day-to-day management and operations. The AID system helps to improve response to incidents by providing rapid information to the proper emergency service providers allowing for shorter incident duration, thereby quicker cleanup operation and bringing the highway back to normal operation. Automatic systems for incident detection are useful in large traffic management systems to detect incidents while operators are busy with other tasks.
