Book excerpt: The Dallas Freeway/High-Occupancy Vehicle Lane System Planning Study is a joint project in cooperation with the Texas Department of Transportation(TxDOT), Dallas Area Rapid Transit (DART), the North Central Texas Council of Governments (NCTCOG), and the Texas Transportation Institute (TTI). The intent of this effort is to assist in the development of an area-wide freeway/HOV system that recognizes implementation constraints (right-of-way and construction costs) and provides reasonable peak-hour operating conditions on all freeway facilities, while incorporating the long-range plans developed by TxDOT, DART, and NCTCOG. The proposed system is a set of recommendations to be considered and evaluated as part of the development of the NCTCOG Mobility 2010 Plan Update, the long-range transportation plan for the Dallas area. HOV facilities are a significant part of the recommended system in the Dallas System Planning Study, and their implementation is important to the successful operation of the Dallas area transportation system in the future. This report, therefore, focuses on the recommended HOV improvements resulting from the methodology. The recommended system in the Dallas System Planning Study was developed using a methodology that focuses on peak-hour passenger travel demand in the year 2015 (derived from the 2010 24-hour volume assignment provided by NCTCOG)for the freeways in Dallas and surrounding counties. The goal of the Dallas System Planning Study has been to find the lowest-public-cost alternative in each corridor for a give volume of peak-hour person trips. Planning officials summed costs to the public, including construction, right-of-way, operating, and congestion costs for each alternative, and selected the least-public-cost alternative as optimum. This methodology uses an iterative process that balances money saved in construction against money lost in delay to find the optimum combination of mixed-flow, HOV, and express lanes necessary to move the demand. It also recognizes that some motorists will change their mode of travel when given the opportunity to avoid congestion, resulting in more transit and carpool use. (Rail passenger volumes were held constant as provided by NCTCOG).

Book excerpt: Limited capital investment for major transportation improvements and growth in metropolitan areas require the most efficient use of the existing transportation system. One means to achieve this is high-occupancy vehicle (HOV) lanes. While an extensive system of permanent HOV lanes is planned for the Dallas-Fort Worth urbanized area, the Texas Department of Transportation (TxDOT) and Dallas Area Rapid Transit (DART) have pursued and continue to pursue short-term or interim HOV lane projects that would enhance public transportation and overall mobility. There are currently 57 km (35.4 mi) of interim HOV lanes operationalin the Dallas area, including a barrier separated contraflow lane on I-30 (East R.L. Thornton Freeway) and buffer-separated concurrent flow HOV lanes on I-35E North (Stemmons Freeway) and I-635 (Lyndon B. Johnson Freeway). The objective of this research is to investigate the operational effectiveness of the new concurrent flow HOV lanes in the Dallas area, as well as to assess the effectiveness of concurrent flow (buffer-separated) versus contraflow (barrier-separated) HOV lanes. Issues such as person movement, carpool formation, travel time savings, violation rates, and project cost effectiveness are addressed. By understanding the operational performance and issues of both concurrent flow (buffer-separated) HOV lanes and contraflow (barrier-separated) HOV lanes, recommendations can be made on suggested HOV lane policies, including the type of permanent HOV lanes to be implemented in the Dallas area.

Download or read book Highway Planning and Operations for the Dallas District written by John C. Brunk and published by . This book was released on 1997 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The System Planning Methodology was developed jointly by the Texas Department of Transportation (TxDOT), North Central Texas Council of Governments (NCTCOG), Dallas Area Rapid Transit (DART), and Texas Transportation Institute (TTI) as a transportation corridor and system analysis tool that would bridge the gap between regional planning and detailed corridor design. It allows for the examination of peak hour person movement for different facility types within a corridor and estimates associated public costs (e.g., right-of-way, construction, operation, congestion, and environmental costs). The objective of the methodology is to find the lowest total public cost alternative. This project extends the methodology to include costs associated with traffic incidents (nonrecurrent congestion) and tests the results on five corridors in the Dallas area to determine if it alters the recommended alternative previously identified for each corridor. It also adds toll lanes and high occupancy/toll lanes (HOT) as alternatives that can be evaluated against other combinations of general purpose lanes, high occupancy vehicle (HOV) lanes, and express lanes.
Book Synopsis Incorporating Intermodalism Into Freeway System Planning by : Carol H. Walters
Download or read book Incorporating Intermodalism Into Freeway System Planning written by Carol H. Walters and published by . This book was released on 1996 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research enhances the Dallas System Planning Study, which presented a methodology for selecting the least-cost alternative for freeway improvement projects for the Dallas area. This study includes data from other freeway and High Occupancy Vehicle (HOV) systems from around the country. The congestion cost analysis was improved by developing a linear relationship between vehicular volume or flow and delay. Cost estimating procedures for fuel consumption, and delay to passenger and commercial vehicles are included in the alternative analysis. The new methodology is a more complete analysis of the costs and benefits of alternatives, and is applicable to other communities in their selection of freeway improvement alternatives. It also allows the alternative with the least energy consumption to be identified. The results of this project will be implemented to reduce energy consumption in Texas by allowing planning teams to select the least energy intensive alternative being considered for any freeway corridor or system plan.

Available in PDF, EPUB and Kindle. Book excerpt: This study reexamines the traditional use of the 30th highest hourly volume as the optimum design hour volume given the current era of limited funding, constrained right-of-way, environmental concerns, and increasing congestion. The report documents the Dallas/Ft. Worth region's use of an alternative design hour volume (4th highest hour of the day) based on funding constraints. The use of an alternative design hour volume requires that the planned system be optimized to manage peak person trip flows by identifying the best mix of general purpose, high occupancy and express lanes, and an aggressive program of transportation system management and demand management strategies A methodology is outlined to use a peak hour traffic model to forecast traffic volumes for different hours of the day. This approach has the potential to avoid some of the shortcomings of using average values for peak hour factors, directional split, and trucks to obtain hourly design volumes from daily forecasts. If congestion is accepted during the peak hours of the day, then the design process for a facility must expressly consider congested conditions. Nine design elements that pose operational/safety concerns were examined under congested conditions to identify basic guidelines that should be considered when designing for congestion.

Book Synopsis Traffic Demand Analysis in Major Investment Studies by : John C. Brunk
Download or read book Traffic Demand Analysis in Major Investment Studies written by John C. Brunk and published by . This book was released on 2000 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal regulations and guidance define major investment studies (MIS) as a flexible framework that can be tailored to provide the information needed to make local decisions about transportation investments. It is intended to enhance the planning process by requiring consideration of a broad array of alternatives and higher levels of public participation early in the process. The consideration of mobility and accessibility improvements, and operating efficiencies in the development and evaluation of alternatives is encouraged, but no particular approach or level of detail is required concerning traffic demand analysis. This project examines 13 completed MISs to identify the state-of-the-practice of traffic demand analysis employed in Texas and around the country. An examination of the methods identified was compiled in a range of analysis alternatives from planning-level down to microscopic analysis of freeway flow. Guidelines are included to help agencies conduct an MIS that adequately addresses traffic demand.
