  • Ken Matthews: 1934-2019
    KEN MATTHEWS: 1934-2019 The world’s racewalking community was saddened in June 2019 to hear of the passing of Ken Matthews, Great Britain’s last surviving Olympic race walking Gold medallist. His death occurred on the evening of Sunday 2 nd June in Wrexham where he was a hospital in-patient. Kenneth ("Ken") Joseph Matthews was born on 21 June 1934 in Birmingham and started his race walk career as an 18- year-old, following in the footsteps of his father, Joe, who was a founding member of the now defunct Royal Sutton Coldfield Walking Club. Throughout his athletics career, Ken remained Midlands based, and remained a loyal member of Royal Sutton Coldfield Walking Club. An electrical maintenance engineer at a power station near his hometown of Sutton Coldfield, he became one of England's most successful ever racewalkers and dominated the world stage throughout the early 1960's. He won 17 national titles, as well as Olympic and European gold and, between 1964 to 1971 he held every British record from 5 miles to 2 hours, including a 10-mile world best of 69:40.6. Perhaps surprisingly, he did not dominate as a youngster and it was not until 1959, at age 25, that he won his first British titles – the RWA's 10 miles road title and the AAA's 2 miles and 7 miles track titles. 1 From then on, he was pretty much unbeatable in England, but the British race most people remember is, interestingly, a loss rather than a victory. In spectacle, excitement and sheer athleticism, the 1960 AAA 2 mile duel between Stan Vickers and Ken stands comparison with any of the great races in the history of the championships.

  • The Effects of Roundabouts on Pedestrian Safety
    The Effects of Roundabouts on Pedestrian Safety Prepared for The Southeastern Transportation Center University of Tennessee – Knoxville Knoxville, Tennessee Prepared by John R. Stone, Ph.D KoSok Chae & Sirisha Pillalamarri Department of Civil Engineering North Carolina State University Raleigh, NC 27695-7908 Funded by The Southeastern Transportation Center With a Grant from The University Transportation Centers Program U.S. Department of Transportation August 2002 NCSU Preface This project examines the safety aspects of modern roundabouts with respect to pedestrians. Since the emergence of modern roundabouts in the US, safety has been recognized as a major concern for the effectiveness of roundabout performance. Pedestrians may be more prone to unsafe crossings at roundabouts due to new geometries, signalization (or lack of it), right of way assignments for pedestrians and vehicles, and visual and auditory cues. This project documents case study, statistical, and simulation analyses regarding pedestrian safety at roundabouts. The results suggest that roundabouts are safe with respect to pedestrians. This report includes the following topics: • literature review summarizing international and US experience with roundabouts and pedestrians, • alternative research approaches, • case study analysis of a candidate roundabout intersection in Raleigh, NC, • statistical analysis for pedestrian crashes at the case study intersection, and • simulation of the case study intersection vehicle and pedestrian movements with the original intersection and with the candidate roundabout. Copies of the report are available from the Southeastern Transportation Center, University of Tennessee – Knoxville. We hope that the results of this research will continue to prove valuable to the roundabout community. i NCSU Acknowledgements The faculty and students who worked on this project gratefully appreciate the financial support of a “seed grant” from the Southeastern Transportation Center at the University of Tennessee-Knoxville under the auspices of the USDOT University Centers Program.

  • Won't Crosswalks Make It Safer to Cross Streets?
    About Cross Walks: Won’t Crosswalks make it safer to cross streets? A crosswalk is that area of a roadway where pedestrians have the right of way. Crosswalks may be “marked” or “unmarked”. A “marked crosswalk” is any crosswalk which is delineated by painted markings placed on the pavement. All other crosswalk locations are therefore “unmarked”. Under the Arizona Law, crosswalks exist at all intersections, extending across the street from the corner curbs, or on other parts of the street designated as pedestrian crossing locations by the painted lines, unless signed otherwise. Arizona State law states the following in ARS 28-793. Crossing at other than crosswalk A. A pedestrian crossing a roadway at any point other than within a marked crosswalk or within an unmarked crosswalk at an intersection shall yield the right-of-way to all vehicles on the roadway. B. A pedestrian crossing a roadway at a point where a pedestrian tunnel or overhead pedestrian crossing has been provided shall yield the right-of- way to all vehicles on the roadway. C. Between adjacent intersections at which traffic control signals are in operation, pedestrians shall not cross at any place except in a marked crosswalk. Q: Are marked crosswalks safer than unmarked crosswalks? A: The City of San Diego conducted a study on the issue in the 1970's, and the report conclusions are often cited as the first comprehensive study of crosswalk safety. Investigators in San Diego observed over 400 intersections during a five-year study period. The results demonstrated that during the five- year period, 177 pedestrians were hit in 400 marked crosswalks compared to 31 pedestrians hit in 400 corresponding unmarked crosswalks.

  • Shared Streets and Alleyways – White Paper
    City of Ashland, Ashland Transportation System Plan Shared Streets and Alleyways – White Paper To: Jim Olson, City of Ashland Cc: Project Management Team From: Adrian Witte and Drew Meisel, Alta Planning + Design Date: February 2, 2011 Re: Task 7.1.O White Paper: “Shared Streets and Alleyways” - DRAFT Direction to the Planning Commission and Transportation Commission Five sets of white papers are being produced to present information on tools, opportunities, and potential strategies that could help Ashland become a nationwide leader as a green transportation community. Each white paper will present general information regarding a topic and then provide ideas on where and how that tool, strategy, and/or policy could be used within Ashland. You will have the opportunity to review the content of each white paper and share your thoughts, concerns, questions, and ideas in a joint Planning Commission/Transportation Commission meeting. Based on discussions at the meeting, the material in the white paper will be: 1) Revised and incorporated into the alternatives analysis for the draft TSP; or 2) Eliminated from consideration and excluded from the alternatives analysis. The overall intent of the white paper series is to explore opportunities and discuss the many possibilities for Ashland. Shared Streets Introduction Shared Streets aim to provide a better balance of the needs of all road users to improve safety, comfort, and livability. They are similar to European concepts such as the Dutch based ‘Woonerf’ and the United Kingdom’s ‘Home Zone’, with some distinct differences. This balance is accomplished through integration rather than segregation of users. By eschewing many of the traditional roadway treatments such as curbs, signs, and pavement markings, the distinction between modes is blurred.

Words: 5199 + 3*250 (tables) + 6*250 (figures) = 7449 words November 2003 TRB 2004 Annual Meeting CD-ROM Paper revised from original submittal. Fitzpatrick, Ullman, Trout 2 ABSTRACT On-street pedestrian surveys were used to obtain the perspectives of pedestrians with regards to their experiences and needs at pedestrian crossing locations. Seven sites with five different treatments were ultimately selected for study. These treatments consisted of two marked crosswalk treatments, an in-roadway warning light treatment, a Hawk treatment, two Split Midblock Signal treatments, and a countdown pedestrian signal treatment at a signalized intersection. The survey was administered at the selected locations where pedestrians could be approached after they crossed at the study site. It was found through this study that as the control at a pedestrian crossing increases through the addition of signs, flashing lights, and/or signals, the pedestrians’ perception of safety also increases. Based on the responses of the survey participants, the factors that have the greatest influence on the pedestrian responses were: traffic volume, turning traffic, presence of disabled pedestrians, traffic speed, and the availability of an alternate crossing.
