Book excerpt: The main purpose of this research was to find out the characteristics of bicycle-related crashes and improve safety and comfort for bicyclists around signalized intersections in Louisville, KY. At first, the benefits of bicycling for accessibility, health, environment and traffic were discussed. Plans made by a number of states, regions and local governments for encouraging people to use bicycles as an alternative to motor-vehicles were introduced. Emphases were put on the introduction of the Louisville Metro Bike Master Plan, which aimed to increase bicycling activity throughout all parts of Louisville by making it a fun, comfortable and accessible mode of travel, and to simultaneously reduce the number of cyclists killed and injured in crashes with motor vehicles. Second, an elaborative literature interview was made to look for the reasons which caused crashes between bicyclists and drivers. The conclusion was that a large percentage of bicyclists-related crashes happened at intersections. The most important reason for bicyclists-related crashes was drivers' failing to yield when they were entering turning movements. Third, research for possible solutions which were used to improve safety for bicyclists was made. Studies which evaluated the effectiveness of those solutions were discussed. Fourth, in order to determine the characteristics of bicyclists-related crashes in Louisville, crash data of 10 years (from 2003 to 2012) was collected from the Kentucky Collision Analysis for the Public. Bicycle-related crashes in Louisville were most prevalent in the summer months, on weekdays and in the afternoon peak period in clear weather conditions. Turning-right was one of three highest possible pre-crash maneuvers in all bicycle-related crashes in Louisville The most important factor causing bicyclists-related crashes was motorists' inattentiveness, or failing to yield the right-of-way to bicyclists. Bicyclists' inattentiveness or failing to yield the right-of-way was also important for bicyclists-related crashes. Fifth, surveys were made four times to evaluate the effectiveness of a newly-developed countermeasure for bicyclists' safety. The conclusion was that this countermeasure for bicyclists' safety couldn't influence the distance from the curb where motor-vehicle crossed the stop bar. Most drivers preferred 4-6 feet away from the curb when they crossed the stop bar. This countermeasure for bicyclists' safety could attract about 40% of drivers to cross the boundary between the bicycle lane and the traffic lane and to enter the right-of-way of the bicycle lane. More than 50% of drivers needed 60-100 feet to finish the process of entering the right-of-way of the bicycle lane from the adjacent traffic lane. In short this newly-developed countermeasure for bicyclists' safety could greatly improve bicyclists' safety at intersections by changing drivers' right-turning movements. At last, some possible improvements for this new countermeasure were discussed to better this countermeasure in the future.

Available in PDF, EPUB and Kindle. Book excerpt: A before-and-after analysis was performed at eleven intersections where a bike box was installed in Portland, Oregon to explore the safety effects of the treatment. Video data were gathered prior to installation at 14 intersections where a bike box installation was planned by the Portland Bureau of Transportation. Cameras were set up to capture three full twenty-four hour days (72 hours) of data for each intersection from Tuesday through Thursday. Of the 14 original selected intersections, 11 intersections actually received the bike box treatment. Video data were again gathered for these intersections after the installation of the bike box for another three full twenty-four hour days (72 hours) between Tuesday and Thursday. One day of data (24 hours) was selected for observation from both the before and after periods in the analysis for each study intersection during midweek. Safety effects were evaluated by three metrics: 1) observed conflicts; 2) observed cyclist behavior for all conflicts as measured by head or shoulder checks; and 3) reported crash data. To develop the conflict data, a log was created of each motor vehicle and bicycle passing through the intersection for approximately 528 hours of video. All conflicts that were observed during the period were further reviewed by an expert panel that scored conflicts by severity. Following this review, a total of 18 conflicts were observed during the before period. The total exposure in the before period was 39,497 motor vehicles in the vehicle lane adjacent to the bike lane (10,454 of which were right-turning) and 7,849 bicycles. A total of 19 conflicts were observed during the after period. Total exposure was 42,381 motor vehicles in the vehicle lane adjacent to the bike lane (11,053 of which were right-turning) and 5,852 bicycles. The sample size of observed conflicts was insufficient to draw statistically significant conclusions for any of the specific intersections that were treated. When taking in account the total amount of conflicts, the limited data suggest a slight increase in the rate of conflicts when normalized against a product of right-turning vehicles and bicycles observed in the intersection. The data also suggest that the installation of a bike box at an intersection reduces the rate of conflicts per hundred motor vehicles and increases the rate of conflicts per hundred bicyclists. Data regarding head-checks from the bicyclist shows an increase in bicyclists observing the possibility of conflicts approaching from behind as they pass through the intersection. A review or crash data at each of the intersections shows an increase at three of the observed intersections and a decrease at the remaining five.

Download or read book Urban Street Design Guide written by National Association of City Transportation Officials and published by Island Press. This book was released on 2013-10-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NACTO Urban Street Design Guide shows how streets of every size can be reimagined and reoriented to prioritize safe driving and transit, biking, walking, and public activity. Unlike older, more conservative engineering manuals, this design guide emphasizes the core principle that urban streets are public places and have a larger role to play in communities than solely being conduits for traffic. The well-illustrated guide offers blueprints of street design from multiple perspectives, from the bird’s eye view to granular details. Case studies from around the country clearly show how to implement best practices, as well as provide guidance for customizing design applications to a city’s unique needs. Urban Street Design Guide outlines five goals and tenets of world-class street design: • Streets are public spaces. Streets play a much larger role in the public life of cities and communities than just thoroughfares for traffic. • Great streets are great for business. Well-designed streets generate higher revenues for businesses and higher values for homeowners. • Design for safety. Traffic engineers can and should design streets where people walking, parking, shopping, bicycling, working, and driving can cross paths safely. • Streets can be changed. Transportation engineers can work flexibly within the building envelope of a street. Many city streets were created in a different era and need to be reconfigured to meet new needs. • Act now! Implement projects quickly using temporary materials to help inform public decision making. Elaborating on these fundamental principles, the guide offers substantive direction for cities seeking to improve street design to create more inclusive, multi-modal urban environments. It is an exceptional resource for redesigning streets to serve the needs of 21st century cities, whose residents and visitors demand a variety of transportation options, safer streets, and vibrant community life.

Book excerpt: "From traffic-dodging-bike messengers to tattooed teenagers on battered bikes, from riders in spandex to well-dressed executives, ordinary citizens are becoming transportation revolutionaries. Jeff Mapes traces the growth of bicycle advocacy and explores the environmental, safety, and health aspects of bicycling. He rides with bicycle advocates who are taming the streets of New York City, joins the street circus that is Critical Mass in San Francisco, and gets inspired by the everyday folk pedaling in Amsterdam, the nirvana of American bike activists. Chapters focused on big cities, college towns, and America's most successful bike city, Portland, show how cyclists, with the encouragement of local officials, are claiming a share of the valuable streetscape."--BOOK JACKET.

Download or read book Guidelines for Medial and Marginal Access Control on Major Roadways written by Vergil G. Stover and published by Highway Research Board. This book was released on 1970 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The full range medial and marginal control, in cases of both full and partial control of access was studied to enable the highway administrator to determine the appropriate degree of access control, and to provide him with the physical means of accomplishing such control. Access control is of principal importance in insuring that an arterial, once constructed and opened to traffic, will continue to have a high traffic movement capability in future years. The street and highway networks of local areas, urban regions, states, and the nation should adequately provide for the conflicting functions of land access and longer trips.
