Austroads is the peak organisation of Australasian road transport and traffic agencies. Part 10: Traffic Control and Communication Devices is concerned with the tools that are required for traffic management and traffic control within a Austroads’ purpose is to support our member network. It covers the various control devices used to regulate and guide organisations to deliver an improved Australasian traffic, including signs, traffic signals, pavement markings, delineators, and road transport network. To succeed in this task, we traffic islands. Other devices and technologies that convey information and undertake leading-edge road and transport guidance to road users while they are active in traffic are also included. research which underpins our input to policy development and published guidance on the Part 10 provides guidance on the design and use of particular traffic control design, construction and management of the road devices that are applied to achieve or implement traffic management and network and its associated infrastructure. control measures.

  • (Keeping Safe Distances from Bicycles) Bill 2014 Second Reading Speech Hon Lynn Maclaren MLC - 20 March 2014
    Road Traffic Amendment (Keeping Safe Distances from Bicycles) Bill 2014 Second Reading Speech Hon Lynn MacLaren MLC - 20 March 2014 I move that the Bill be now read a second time. Cyclists need a protective buffer when sharing roads with motorists. Current Western Australian road rules require drivers of motor vehicles to allow ‘sufficient’ overtaking distance when passing a bicycle rider. ‘Sufficient’ is an inadequate and unclear description that has repeatedly failed to protect bicycle riders. Amendments to road rules to specify a minimum distance are critical to improving the safety of bicycle riders. As specified in the Road Traffic Code 2000, a safe passing distance between a cyclist and a motor vehicle is considered to be “a sufficient distance to avoid a collision with that vehicle or to avoid obstructing the path of that vehicle.” 1 In addition, a safe distance behind a vehicle is considered to be a distance at which it “will enable the driver to stop the vehicle in an emergency with safety, and without running into the vehicle in front of him or her.”2 Legislative amendment, with appropriate education and enforcement, to mandate a minimum distance that motorists must keep from bicycle riders is currently the single most important action needed to reduce bicycle rider fatalities. There is an ethical issue when comparing dangerous behaviour by motorists to risky behaviour by cyclists. The driver endangers the cyclist, not vice versa, and it is rare for a cyclist or pedestrian to injure another road user. As reported on the ABC’s 7.30 programme last Friday night, there's no doubt who comes off second best when a car and a bike collide.

NRTC Programs: Implementation of Reforms. Key Milestones: Approval of the Australian Road Rules by the Australian Transport Council in January 1999. Consideration of amendments to the Rules by representatives of all jurisdictions, meeting as the Australian Road Rules Maintenance Group during March to September 1999 and Parliamentary Counsel of each State and Territory. Abstract: Amendments are required to clarify the intent of particular provisions in the Australian Road Rules; to incorporate corrections and rectify omissions largely of a minor nature; to enable the finalisation and subsequent publication of the amended Australian Road Rules, so that States and Territories can proceed without delay to their implementation on 1 December 1999; and to ensure that the Australian Road Rules, when implemented, make the maximum contribution to road safety and the efficient movement of traffic on Australia’s roads.

  • Traffic and Road Sign Recognition
    Traffic and Road Sign Recognition Hasan Fleyeh This thesis is submitted in fulfilment of the requirements of Napier University for the degree of Doctor of Philosophy July 2008 Abstract This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. The system is based on three major stages: colour segmentation, recognition, and classification. Four colour segmentation algorithms are developed and tested. They are a shadow and highlight invariant, a dynamic threshold, a modification of de la Escalera’s algorithm and a Fuzzy colour segmentation algorithm. All algorithms are tested using hundreds of images and the shadow-highlight invariant algorithm is eventually chosen as the best performer. This is because it is immune to shadows and highlights. It is also robust as it was tested in different lighting conditions, weather conditions, and times of the day. Approximately 97% successful segmentation rate was achieved using this algorithm. Recognition of traffic signs is carried out using a fuzzy shape recogniser. Based on four shape measures - the rectangularity, triangularity, ellipticity, and octagonality, fuzzy rules were developed to determine the shape of the sign. Among these shape measures octangonality has been introduced in this research. The final decision of the recogniser is based on the combination of both the colour and shape of the sign. The recogniser was tested in a variety of testing conditions giving an overall performance of approximately 88%.

Printed in the United States of America oi.uchicago.edu PREFACE HE book contains twelve chapters, but it can be broken up structurally into five parts. First, the place of writing among the various systems of human inter­ communication is discussed. This is followed by four Tchapters devoted to the descriptive and comparative treatment of the various types of writing in the world. The sixth chapter deals with the evolution of writing from the earliest stages of picture writing to a full alphabet. The next four chapters deal with general problems, such as the future of writing and the relationship of writing to speech, art, and religion. Of the two final chapters, one contains the first attempt to establish a full terminology of writing, the other an extensive bibliography. The aim of this study is to lay a foundation for a new science of writing which might be called grammatology. While the general histories of writing treat individual writings mainly from a descriptive-historical point of view, the new science attempts to establish general principles governing the use and evolution of writing on a comparative-typological basis.
