Available in PDF, EPUB and Kindle. Book excerpt: Congested freeways are often located in urban areas with constrained environments and/or rights-of-way where significant widening of the roadway is not practical due to adjacent developments and land use, physical constraints, along with limited availability of funding. Among the strategies for increasing freeway capacity in such constrained environments — and thereby reducing congestion and improving operations — is to add a travel lane within the existing roadway footprint by reducing the widths of the existing lanes and/or shoulders. The additional lane may be utilized by all traffic at all times, as a special use or managed lane that is open only to specific types of vehicles or movements (e.g., High Occupancy Toll (HOT) lane, exit only lane), or only during selected times of the day and/or when congestion warrants opening the lane (e.g., temporary shoulder use). Narrow lanes and shoulders may be applied to add capacity on the freeway mainline and in interchange areas including ramps. This primer provides information to policy makers, transportation agency managers, designers and operators on the use of narrow lanes and narrow shoulders to improve capacity within an existing roadway footprint. Much of the information contained in the primer is presented in the broader context of both Performance Based Planning and Programming (PBPP) and Performance — Based Practical Design (PBPD). Primer contents include case studies on the use of narrow lanes, issues and approaches for analyzing the operational and safety impacts of narrow lanes and narrow shoulders, and the role of transportation systems management and operations (TSMO) in support of narrow lanes operations.

This book was released on 2005 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: As traffic volumes grow on urban freeways, highway agencies face an ongoing challenge to maintain efficient traffic operations and acceptable levels of service. Increasing the capacity of a freeway by adding a lane can be difficult and expensive if it involves widening the existing roadbed, regrading roadside areas, and/or acquiring additional right-of-way. A number of highway agencies, however, have implemented projects in which a travel lane is added on an urban freeway by restriping the traveled way with narrower lanes, converting all or part of the shoulder to a travel lane, or a combination of both. The traffic operational benefits of such conversions are immediate and obvious, but the safety effects are uncertain. This study addresses these safety effects.

Book Synopsis Efficient Use of Highway Capacity Summary by : Beverly T. Kuhn
Download or read book Efficient Use of Highway Capacity Summary written by Beverly T. Kuhn and published by . This book was released on 2010 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report was developed to summarize the implementation of safety shoulders as travel lanes as a method to increase the efficient use of highway capacity. Its purpose is to provide a succinct overview of efforts to use left or right shoulder lanes as temporary or interim travel lanes. As part of this summary, information related to the impact of that shoulder usage on highway safety and/or accidents during operations was reviewed as well. The intent of the report is to provide critical information that the Federal Highway Administration (FHWA) can use to formulate guidance for agencies on providing temporary shoulder use as a means of increasing roadway capacity. The study that generated this product was conducted at the request of Congress through the 2008 Technical Corrections Act. Those issues that need to be considered include design, traffic control devices, performance measures, potential safety benefits, maintenance concerns, enforcement roles and processes, incident response, training for personnel, costs, liability and legal issues, and public outreach and education. Careful consideration of these issues can help ensure a shoulder use deployment is effective without having negative impacts on safety and operations"--Technical report documentation page.
Book Synopsis Reducing Lane and Shoulder Width to Permit an Additional Lane on a Freeway by : Karen Dixon
Download or read book Reducing Lane and Shoulder Width to Permit an Additional Lane on a Freeway written by Karen Dixon and published by . This book was released on 2015 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research effort identified the operational and safety implications of using reduced lane and shoulder widths for a variety of freeway configurations. The research team used speed, crash, and geometric data for freeways in Dallas, Houston, and San Antonio. The operational analysis identified an increase of about 2.2 mph in speed for a 12-ft lane as compared to an 11-ft lane. The shoulder width is significant when the adjacent lane is 11-ft wide, but not when it is 12- ft wide which suggests that left shoulder width is more important with a reduced lane width. Operating speeds on Texas freeways are 2 mph lower during night time (with roadside lighting present) than during the day. Speeds were higher (by 1.5 mph) on the weekends (Saturday) than on the week day studied (Wednesday). The safety analysis determined a crash difference when comparing freeways with 12 ft to 11 ft lanes. There is a reduction in KAB crashes that ranges from 5% for 2-lane freeways up to 12% for 5-lane freeways, other roadway characteristics equal. Similarly, there are crash reductions associated with each additional lane, increased left shoulder widths, and increased right shoulder widths. While constructing an additional lane is beneficial in terms of safety, a larger safety detriment caused by narrow lanes or shoulders annuls such benefit. However, if it is possible to increase the total paved width when adding a travel lane, the safety model allows the analyst to identify lane and shoulder widths so that the number of crashes along the corridor will expectedly remain unchanged.

Available in PDF, EPUB and Kindle. Book excerpt: “Sites provides crucial context on how Chicago’s Afrocentrist philosophy, religion, and jazz scenes helped turn Blount into Sun Ra.” —Chicago Reader Sun Ra (1914–93) was one of the most wildly prolific and unfailingly eccentric figures in the history of music. Renowned for extravagant performances in which his Arkestra appeared in neo-Egyptian garb, the keyboardist and bandleader also espoused an interstellar cosmology that claimed the planet Saturn as his true home. In Sun Ra’s Chicago, William Sites brings this visionary musician back to earth—specifically to the city’s South Side, where from 1946 to 1961 he lived and relaunched his career. The postwar South Side was a hotbed of unorthodox religious and cultural activism: Afrocentric philosophies flourished, storefront prophets sold “dream-book bibles,” and Elijah Muhammad was building the Nation of Islam. It was also an unruly musical crossroads where the man then known as Sonny Blount drew from an array of intellectual and musical sources—from radical nationalism, revisionist Christianity, and science fiction to jazz, blues, Latin dance music, and pop exotica—to construct a philosophy and performance style that imagined a new identity and future for African Americans. Sun Ra’s Chicago shows that late twentieth-century Afrofuturism emerged from a deep, utopian engagement with the city—and that by excavating the postwar black experience of Sun Ra’s South Side milieu, we can come to see the possibilities of urban life in new ways. “Four stars . . . Sites makes the engaging argument that the idiosyncratic jazz legend’s penchant for interplanetary journeys and African American utopia was in fact inspired by urban life right on Earth.” —Spectrum Culture
