In addition, since modeling vehicular interactions via simulation is intrinsic to the methodology, one may assess various impacts of safety treatments without disrupting vehicle movements and before proceeding with real-world implementations. VISSIM, a microscopic traffic simulation model, is used in this thesis to reproduce vehicular interactions of an urban High Occupancy Vehicle (HOV) arterial in Québec.

  • Design Guidelines for the Use of Curbs and Curb/Guardrail
    DESIGN GUIDELINES FOR THE USE OF CURBS AND CURB/GUARDRAIL COMBINATIONS ALONG HIGH-SPEED ROADWAYS by Chuck Aldon Plaxico A Dissertation Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Doctor of Philosophy in Civil Engineering by September 2002 APPROVED: Dr. Malcolm Ray, Major Advisor Civil and Environmental Engineering Dr. Leonard D. Albano, Committee Member Civil and Environmental Engineering Dr. Tahar El-Korchi, Committee Member Civil and Environmental Engineering Dr. John F. Carney, Committee Member Provost and Vice President, Academic Affairs Dr. Joseph R. Rencis, Committee Member Mechanical Engineering ABSTRACT The potential hazard of using curbs on high-speed roadways has been a concern for highway designers for almost half a century. Curbs extend 75-200 mm above the road surface for appreciable distances and are located very near the edge of the traveled way, thus, they constitute a continuous hazard for motorist. Curbs are sometimes used in combination with guardrails or other roadside safety barriers. Full-scale crash testing has demonstrated that inadequate design and placement of these systems can result in vehicles vaulting, underriding or rupturing a strong-post guardrail system though the mechanisms for these failures are not well understood. For these reasons, the use of curbs has generally been discouraged on high-speed roadways. Curbs are often essential, however, because of restricted right-of-way, drainage considerations, access control, delineation and other curb functions. Thus, there is a need for nationally recognized guidelines for the design and use of curbs. The primary purpose of this study was to develop design guidelines for the use of curbs and curb-barrier combinations on roadways with operating speeds greater than 60 km/hr.

  • ROAD SAFETY: BASIC FACTS © Panos / Jacob Silberberg
    FACT SHEET #1 ROAD SAFETY: BASIC FACTS © Panos / Jacob Silberberg ROAD SAFETY AND MEDIA REPORTING Road traffic crashes are often covered in the media simply as events—not as a leading killer of people and an enormous drain on a country’s human, health and financial resources. By framing road safety as a health and development story, with data and in-depth information, journalists have the opportunity to affect the way these stories are told and potentially to help shift public behaviour and attitudes, influence policy and therefore contribute towards saving lives. WHY ARE ROAD TRAFFIC INJURIES A PUBLIC HEALTH ISSUE? Road traffic injuries and deaths have a terrible 1.25 million impact on individuals, communities and road traffic deaths occur every year. countries. They involve massive costs to often overburdened health care systems, occupy scarce hospital beds, consume resources and result in significant losses of productivity and prosperity, with deep social and economic repercussions. The numbers speak for themselves: this is a cause of death among public health and development crisis that is expected to worsen unless action is taken. #1those aged 15-29 years For more on: road traffic injuries Global death figures drive home the extent of this public health crisis, especially among young people.

  • A New Signalling System for Automatic Block Signal Between Stations Controlling Through an IP Network
    A New Signalling System for Automatic Block Signal between Stations Controlling through an IP Network 1R. Ishima, 1Y. Fukuta, 1M. Matsumoto, 2N. Shimizu, 3H. Soutome, 4M. Mori East Japan Railway Company, Saitama, Japan1; Daido Signal Co.,Ltd., Tokyo, Japan2; Hitachi, Ltd., Hitachinaka, Japan3; Toshiba Corp., Tokyo, Japan4 Abstract This paper describes a new signalling system which controls signalling field devices of automatic block signal between stations through an IP network. The system improves the method of the system already installed to Ichikawaono station on the Musasino line in February 2007. The Logic Controller (LC), placed in a signal house, exchanges the command and feedback data with the Field Controller (FC), placed near each automatic block signal, through the Ethernet Passive Optical Network (E- PON). Following the command data, the FC electrically controls signalling field devices such as signals, track circuits, transponders of the Automatic Train Stop (i.e. Automatic Train Protection) system with Pattern (ATS-P), transponders of the S-type of ATS (ATS-S), and output relays. Only optical fiber cable requires between the LC and the FC. The system has high reliability because the LC, the FC, and the data paths of E-PON are all duplex. The system provides sufficient maintenance information through the IP network. The system can realize higher reliability, less wire-connection- work, less amount of cable, cost cutting, and faster troubleshooting. A prototype system was under evaluation on the Joban Rapid Service line between Mabashi and Kitakashiwa from August 2006 to January 2008. Evaluating the results of the field test, we conclude that the prototype system is technically suitable for signal control.

  • State Set to Push Toll Roads
    State set to push toll roads FUNDING PLAN AIMS TO SPEED UP ROAD PROJECTS, TRAFFIC RELIEF By Gary Richards Mercury News Thursday, February 3, 2005 The future of highway driving in California could be a two-tiered system, in which commuters can either remain in stop-and-go traffic for free, or pay a toll to cruise on a private highway. Gov. Arnold Schwarzenegger is expected to soon announce his support for allowing private contractors to build toll roads across California. Following the model of Highway 125 now under construction in Southern California, contractors would build toll roads in congested areas or toll lanes parallel to existing roads -- such as Highway 152 or Interstate 205 -- that would be designed and maintained by the state. The specifics are still far away, but it is yet another step in the governor's strategy to creatively finance -- and speed up -- highway construction in California without raising taxes. The governor previously noted his support for allowing solo drivers to pay their way into carpool lanes. ``We're going to make an announcement really soon where we're going to look at our whole infrastructure and transportation and we have a very creative way of financing it,'' Schwarzenegger said last week in a meeting with the Orange County Register editorial board, adding: ``We want to approach it in a very radical way and then look at all kinds of transportation.'' The governor's office had no comment Wednesday on the expected announcement, but last year his performance review team called for more toll facilities. ``I'm not surprised,'' said Randy Rentschler of the Metropolitan Transportation Commission in Oakland.
