Your Bicycle and You Correctly

Headlight: A handlebar mounted light makes you visible Your clothing should be comfortable and not get caught in BICYCLING 101 to others (it’s also required by law when riding in the OK, so we’ll expand a little on that. Wear one, and wear it your bike. For short commutes, regular clothing can be just dark). If you are riding where there aren’t street lights (e.g. Your Bicycle and You correctly. Remember “eyes, ears and mouth.” fi ne. Just be sure to strap your right pants leg to keep it from greenways), you’ll need a strong beam. getting caught by the chain or get a chain guard for your bike. Rear Refl ectors: Get one at least For longer commutes, many prefer to wear cycling clothing, Eyes: Your helmet should be level 3 inches wide, and make sure it’s such as jerseys and cycling shorts. Experiment with what works on your head, not tilted back. pointed straight back, not up or for you, and invest in a few quality pieces. The right clothing There should just be room for one down. Refl ectors only work if they can provide you with added visibility during dark or low light or two fi ngers between your eyes are clean, so make sure to wipe yours conditions. You can buy clothing with refl ective panels and/ and the helmet. off occasionally. or piping or add refl ective tape to existing items.

Study of Lighting Systems for Safety Bicycle Rides
WSEAS TRANSACTIONS on ADVANCES in ENGINEERING EDUCATION A. Sivert, F Betin, B. Vacossin, Ph. Dondon Innovative sustainable development teaching at university: Study of lighting systems for safety bicycle rides (1) A. SIVERT1, F BETIN1, B. VACOSSIN1, Ph. DONDON2 (1) Institut Universitaire de Technologie de l’Aisne Département Génie Electrique SOISSONS Laboratory for Innovative Technologies (L.T.I), Team Energy Electric and Associated System (2) Université de Bordeaux, IPB Av Dr A. Schweitzer 33405 Talence Abstract: Numerous countries are nowadays trying to reduce pollution in the cities, in particular noise and CO2 emission. New alternating means of transportation (other than cars) are now encouraged. Bicycle is one of those. However, one of the key points for promoting bicycles downtown is safety rides whatever the traffic and weather conditions. In that way, lighting systems are mandatory to been seen and to see correctly. Unfortunate- ly, reliable technical data is missing. Only a very few commercial data is available on retailer’s web site or in specialized shops. So, in this paper, we propose firstly a didactical scientific “cooking guide” for students, teachers and bicycle users, who want to choose and design their own lighting based on LEDs (light-emitting diode). Optical, thermal, electronic and power management aspects are discussed. And a set of basic answers to the following questions is provided: What is a simple way of measuring brightness? How does one choose an LED and its optics according to the desired lighting? How is the performance of an LED checked? How does one choose a heatsink? How is the regulation of one or more LEDs managed? Secondly, our didactical experi- ence and feed-back of student’s groups in our electrical department is reported and discussed. -

Motorcycle Crash Causation Study: Volume 2—Coding Manual
Motorcycle Crash Causation Study: Volume 2—Coding Manual PUBLICATION NO. FHWA-HRT-18-039 FEBRUARY 2019 Research, Development, and Technology Turner-Fairbank Highway Research Center 6300 Georgetown Pike McLean, VA 22101-2296 FOREWORD The Motorcycle Crash Causation Study, conducted through the Federal Highway Administration Office of Safety Research and Development, produced a wealth of information on the causal factors for motorcycle crashes, and its corresponding Volumes provide perspectives on what crash-countermeasure opportunities can be developed. This study used a crash- and control-case approach developed from the Organisation for Economic Cooperation and Development protocols, which as discussed in this report, has provided insights into more than 1,900 data elements that may be associated with motorcycle-crash causation. The research team produced a final report along with a 14-volume series of supplemental reports that provide an overview of the study and a summary of its observations, the data-collection forms and coding definitions, a tabulation of each data element collected from each form, and selected comparisons with previous studies. It is anticipated that readers will select those Volumes and data elements that provide information of specific interest. This document, Volume 2—Coding Manual, provides the coding conventions used in this study. It provides data that enable the proper interpretation and understanding of the codes assigned to variables of interest during the study. This report will be of interest to individuals involved in traffic safety, safety training, crash and injury reduction, and roadway design and policy making, as well as to motorcycle- and safety-equipment designers, crash investigators and researchers, motorcycle and automotive manufacturers and consumers, roadway users, and human-factors specialists. -

MADE IN GERMANY. Busch + Müller is the leading brand for bicycle lighting. All groundbreaking innovations such as IQ light technology, daytime running light, brake light function, universal headlights for e-bikes and much more originate here. Our new- est headlights pass the 100 Lux mark for dynamo-powered products, while battery-powered headlights even reach 150 Lux. Busch + Müller is Made in Germany. The production facility of the family-owned enterprise has always been in Meinerzhagen, Germany, from its founding in 1925 up until current day. ON or OFF, that is what bicycle light used to be in the past. Today our head- lights contain highly complex electronics. They increase light output and use software to control the LEDs – e.g. for daytime running light, beam boost, standlight, sensor automatic or light at close range. Pictured left is the electro- nic core of our IQ-X headlight with 100 Lux light output. All engineering achie- vements as well as the software originate at Busch + Müller. The circuit board is supplied by a specialist in our immediate neighbourhood. Every headlight is assembled and all its functions are individually tested in Meinerzhagen. Busch + Müller is Made in Germany, uncompromisingly – including the electronics.

This publication does not constitute a national standard, specification or regulation. 16. Abstract Most State and many other transportation departments in the U.S. maintain roadway and/or work zone design manuals containing State specific regulations, policies, and design guidance for their designers and consultants to use. However, those manuals vary widely in the depth of coverage and the work zone design topics offered. National work zone design guidelines are lacking. This series of guidelines for work zone designers covers various work zone safety design topics for states, design manual decision makers, editors, and subject matter experts to develop or enhance their own guidance materials. “Guidelines for Work Zone Designers – Pedestrian and Bicycle Accommodation” provides guidance covering the topic of safely accommodating pedestrians and bicyclists in work zones and is not intended to be a stand-alone document for designing work zone traffic control plans.
