In the Houston demonstration, a 9.6 mile contraflow lane was available for use by buses and vanpools during the morning and afternoon peak periods. In addition to the contraflow lane, a number of other transportation improvements were also implemented in the North Freeway corridor. In particular, bus service was expanded considerably and two park-and-ride lots were built and a third leased from a church. 17. The evaluation focuses on the feasibility18. (in terms of adverse impacts on non- priority users, safety, enforcement, public acceptance, etc.) and effectiveness (in terms of utilization, increased bus and vanpool ridership, etc.) of the contraflow lane. Contraflow operation resulted in an average round-trip travel- time savings of 40 minutes for bus riders and vanpoolers using the contraflow lane during the peak hour. As a result, bus ridership and, to a lesser extent, vanpooling increased considerably. The feasibility of contraflow operation as an HOV priority measure was also demonstrated by this project.

This report presents the final evaluation of the impacts associated with the implementation of a contraflow lane on the North Freeway in Houston, Texas, on August 28, 1979. The evaluation focuses primarily on the feasibility and effectiveness of contraflow operation as a high occupancy vehicle (HOV) priority measure. Cambridge Systematics had primary responsibility for the evaluation of the demonstration project. Ellyn Eder, Cambridge Systematics' project manager for most of the evaluation effort, and Terry Atherton are the principal authors of this report. John Suhrbier, also with Cambridge Systematics, and Fred Wagner of Wagner-McGee Associates also contributed to the evaluation effort. The Metropolitan Transit Authority of Harris County (METRO), assisted by its data collection contractors, Beiswenger, Hoch and Associates, Inc., and the Texas Transportation Institute, was responsible for administering the surveys used to obtain the travel data supporting the evaluation effort. In particular, the efforts of METRO's project manager, Charles A. Fuhs, in coordinating the data collection effort are greatly appreciated. Valuable suggestions and guidance for this evaluation were provided by David Damm and Carla Heaton of the Transportation Systems Center, and Joseph Goodman, the UMTA project manager. iii FACTORS CONVERSION METRIC xv TABLE OF CONTENTS SECTION Page 1.

  • Road Network Selection for Small-Scale Maps Using an Improved Centrality-Based Algorithm
    JOURNAL OF SPATIAL INFORMATION SCIENCE Number 9 (2014), pp. 71–99 doi:10.5311/JOSIS.2014.9.166 RESEARCH ARTICLE Road network selection for small-scale maps using an improved centrality-based algorithm Roy Weiss and Robert Weibel Department of Geography, University of Zurich, Zurich, Switzerland Received: January 31, 2014; returned: March 13, 2014; revised: July 29, 2014; accepted: August 18, 2014. Abstract: The road network is one of the key feature classes in topographic maps and databases. In the task of deriving road networks for products at smaller scales, road net- work selection forms a prerequisite for all other generalization operators, and is thus a fun- damental operation in the overall process of topographic map and database production. The objective of this work was to develop an algorithm for automated road network selec- tion from a large-scale (1:10,000) to a small-scale database (1:200,000). The project was pur- sued in collaboration with swisstopo, the national mapping agency of Switzerland, with generic mapping requirements in mind. Preliminary experiments suggested that a selec- tion algorithm based on betweenness centrality performed best for this purpose, yet also exposed problems. The main contribution of this paper thus consists of four extensions that address deficiencies of the basic centrality-based algorithm and lead to a significant improvement of the results. The first two extensions improve the formation of strokes concatenating the road segments, which is crucial since strokes provide the foundation upon which the network centrality measure is computed. Thus, the first extension en- sures that roundabouts are detected and collapsed, thus avoiding interruptions of strokes by roundabouts, while the second introduces additional semantics in the process of stroke formation, allowing longer and more plausible strokes to built.

  • Dynamic Lane Reversal in Traffic Management
    To appear in Proceedings of the 14th IEEE ITS Conference (ITSC 2011), Washington DC, USA, October 2011. Dynamic Lane Reversal in Traffic Management Matthew Hausknecht, Tsz-Chiu Au, Peter Stone David Fajardo, Travis Waller Department of Computer Science School of Civil and Environmental Engineering University of Texas at Austin University of New South Wales {mhauskn,chiu,pstone}@cs.utexas.edu {davidfajardo2,s.travis.waller}@gmail.com Abstract— Contraflow lane reversal—the reversal of lanes in order to temporarily increase the capacity of congested roads— can effectively mitigate traffic congestion during rush hour and emergency evacuation. However, contraflow lane reversal deployed in several cities are designed for specific traffic patterns at specific hours, and do not adapt to fluctuations in actual traffic. Motivated by recent advances in autonomous Fig. 1. An illustration of contraflow lane reversal (cars are driving on vehicle technology, we propose a framework for dynamic lane the right side of the road). The total capacity of the road is increased by reversal in which the lane directionality is updated quickly and approximately 50% by reversing the directionality of a middle lane. automatically in response to instantaneous traffic conditions recorded by traffic sensors. We analyze the conditions under systems, more aggressive contraflow lane reversal strategies which dynamic lane reversal is effective and propose an integer can be implemented to improve traffic flow of a city without linear programming formulation and a bi-level programming increasing the amount of land dedicated to transportation. formulation to compute the optimal lane reversal configuration An important component of implementing dynamic lane that maximizes the traffic flow.

Introduction The Putney Road Link Road scheme will create a new junction where Putney Road West meets Aylestone Road/Saffron Lane, and create a link road running through to Welford Road/Victoria Park Road. Although it is intended to create a new local access to the business area, the main purpose of the scheme is the creation of the link road which at this stage will extend to the A6 London Road through Victoria Park Road. Although the council claims this scheme is not connected with a further scheme, linking Aylestone Road to Narborough Road through Evesham Road, it is self-evident that it is, and the council says this in the bid for the funding for this first stage.

  • Parkside Development New Link Road Access to the M6 Motorway Proposal
    Richard Ward PINS Reference 3253194; 3253230; and 3253232 Parkside Development New Link Road Access to the M6 Motorway Proposal Page 1 of 20 June 2020 Current Link Road proposal as shown in the Drainage Plan Page 2 of 20 The Current Proposal for the Parkside Link Road by not being a dedicated direct link to the M6 motorway, the Commercial Vehicle Traffic that will be generated by the proposed development(s) in total will impact on the local roads from all directions as measures to prevent are impossible to manage. The following plan of road access to the proposed Parkside development show the Commercial Vehicle Traffic impact on the Local Roads. Where the utilisation of the Motorway M6 junction 22 will be little used with respect to the access to the proposed development from the local roads. The Access was not solved by the previous Parkside Proposals by the developers: 1996 British Coal/Morrisons; 2000+ RailTrack; 2004-2009 Astral Developments; and 2009-2012 Prologis. To whom all had withdrawn due to not being able to solve the Traffic situation, over and above the reason for the development for the need for jobs which has become secondary and not a main issue considering the Parkside proposals having been an issue since 1993 to 2018, (ie 25 years). So the need for jobs is still not the issue the traffic impact still is the issue purely due to the urban location surrounded by a major road infrastructure. It is this that is the problem, due to heavily industrialising an area that the surrounding locality can not cope with the proposed situation – traffic wise.
