This book was released on 1999 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis presents a review of the current practices associated with the techniques and policies employed by state and local transportation agencies to address the many project development issues required for the reconstruction of existing urban and suburban freeways and expressways. This topic is of special interest because there is a need to reconstruct many highway facilities that have been in existence for over 40 years. The need arises both from the deterioration of the infrastructure and from changes in capacity requirements. This synthesis will be of interest to state and local highway design engineers, traffic engineers, finance and contracting specialists, and contracting personnel in these agencies. It will also be of interest to consultants who are engaged in freeway/expressway reconstruction projects. While many of the project development methodologies in practice for reconstruction of urban and suburban freeways and expressways are similar to those used for new construction, there are unique differences that apply primarily to the reconstruction of major urban highway facilities. This report of the Transportation Research Board highlights the similarities and differences in the planning and management of projects as well as in contracting and financing innovations. Methods for effectively managing traffic during the reconstruction process are important to the process, as are traffic control procedures in the work zone. Public participation and public information dissemination related to traffic changes are vitally important to the effective completion of a reconstruction project. Other aspects, such as the design process, including the use of 3-D and 4-D visualization, pavement renewal procedures, environmental impact mitigation and enhancement activities, that are considered in the process are also addressed.

This book was released on 1993 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the improved data base and analysis tools developed as part of Study 1108 for analyzing the travel impacts of freeway maintenance and reconstruction activities. The data base includes the travel impacts of 12 urban freeway reconstruction projects (six in Texas and six outside Texas), the safety impacts of 5 urban freeway reconstruction projects in Texas, the traffic-handling capacities of 33 short-term freeway work zone lane closures, and the diversion characteristics at 11 short-term freeway work zone closures. The analysis tools developed include new procedures for estimating short-term freeway work zone lane closure capacity and a new version of the QUEWZ model named QUEWZ-92.

This book was released on 2000 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.
Download or read book Updated Short term Freeway Work Zone Lane Closure Capacity Values written by Raymond A. Krammes and published by . This book was released on 1992 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recommendations on estimating the capacity of short-term freeway work zone lane closures are presented. The recommendations are based upon 45 hours of capacity counts at 33 different work zones between 1987 and 1991. These new data indicate average capacities for short-term freeway work zone lane closures from 3 to 1 lanes and from 2 to 1 lanes that are significantly higher than older values reported in the 1985 Highway Capacity Manual. A base capacity value of 1,600 pcphpl is recommended for all short-term freeway work zone lane closure configurations.

Download or read book Social and Economic Effects of Elevated Depressed and At grade Level Freeways in Texas written by Jesse L. Buffington and published by . This book was released on 1997 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: To answer questions being raised by abutting residents and businesses about proposed elevated and/or depressed freeway improvements in the urban and suburban areas of Texas, a four year study has been conducted to estimate the social, economic, and environmental effects of such freeway designs. Eight existing, two under construction, and one approved for construction freeway sections have been studied on a before, during, and after construction basis. The sections selected for study range from being in predominately residential-suburban areas to predominantly commercial-industrial downtown areas. The specific effects of the three types estimated for each study section are as follows: (1) social impacts: population changes, neighborhood accessibility, neighborhood cohesion, and community services; (2) economic impacts: relocation and mitigation costs, business sales, property uses and values, tax revenues, employment and income, and user costs; and (3) environmental impacts: aesthetics, drainage and erosion, noise and air pollution, vibration, and hazardous spills. The literature review and a survey of highway agencies in other states were used to determine the appropriate procedures or models and mitigation measures to implement in estimating the social, economic, and environmental impacts of elevated and depressed freeways. Appropriate study site, local, state, and federal agency data were collected, reduced, and analyzed in the conduct of this study. The findings of the study, presented in five separate reports according to types of effect and summarized in this report, can be used with the recommended estimating procedures to estimate the social, economic, and environmental effects of proposed elevated and depressed freeway projects in urban and suburban areas. Then, transportation planning and designing engineers can use such estimates to prepare environmental statements and conduct public hearings on the recommended grade level of each of the proposed freeway projects. The findings from prior studies indicate that freeway grade level differences in selected measures of social and economic activity are statistically significant. However, these differences are negative or positive, depending largely on various locational factors. The results of this study tend to confirm those findings.
