Multi-Purpose Trails Plan
CITY OF COSTA MESA MULTI-PURPOSE TRAILS PLAN JUNE 2016 ACKNOWLEDGMENTS The City of Costa Mesa Multi-Purpose Trails Plan was prepared under the guidance of: Raja Sethuraman, Transportation Services Manager This plan was prepared by KTU+A Planning + Landscape Architecture: John Holloway, Principal, PLA, ASLA, LCI Joe Punsalan, Senior Associate, GISP, PTP, LCI Alison Moss, Associate Mobility Planner, AICP Beth Chamberlin, Associate Planner Juan Alberto Bonilla, Planner Diana Smith, GISP, GIS Manager Kristin Bleile, GIS Analyst This is a project for the City of Costs Mesa with funding provided by the Southern California Association of Governments (SCAG) Sustainability Program. The Sustainability Program is a key SCAG initiative for implementing the Regional Transportation Plan/Sustainable Communities Strategies (RTP/SCS), combining Compass Blueprint assistance for integrated land use and transportation planning with new Green Region Initiative assistance aimed at local sustainability and Active Transportation assistance for bicycle and pedestrian planning efforts. Sustainability Projects are intended to provide SCAG-member jurisdictions the resources to implement regional policies at the local level, focusing on voluntary efforts that will meet local needs and contribute to implementing the SCS, reducing greenhouse gas (GHG) emissions, and providing the range of local and regional benefits outlined in the SCS. The preparation of this report has been financed in part through grant(s) from the Federal Transit Administration (FTA) through the U.S. Department of Transportation (DOT) in accordance with the provisions under the Metropolitan Planning Program as set forth in Section 104(f) of Title 23 of the U.S. Code.

Rumble Strip Basics for More Information About Rumble Strips in Delaware: You’Ve Probably Seen Them, Those Rows of Grooved Patterns Along the Edges of Some Roadways
RUMBLE STRIP BASICS For more information about rumble strips in Delaware: You’ve probably seen them, those rows of grooved patterns along the edges of some roadways. You Go to safety.deldot.gov to find may have heard and felt them as well, if you have additional articles and supplemental info. ever driven over them. You are not likely to forget the sensation – the low-pitched buzzing sound as your vehicle’s tires cross the strips, and the awakening vibration that you feel. Rumble strips A proven, are an effective safety tool used to address head- effective way on and fixed-object crashes occurring on two-lane to improve rural roadways. Like Us on Facebook highway safety In the United States, rural roads account for /delawaredot and save lives. 60% of all fatal crashes; 90% of which occur on two-lane roads. Center line rumble strips alert drivers that they are drifting across the double Follow Us on Twitter yellow line into oncoming traffic. Edge line rumble @delawaredot strips warn drivers that their vehicle is drifting off the edge of the roadway onto a shoulder or unpaved area. Rumble strips are a cost-effective deterrent to roadway departure crashes, saving lives. deldot.gov 302-760-2080 RUMBLE STRIPS Noise Impacts Some concerns have been expressed that the noise generated by vehicles riding over rumble SAVE LIVES strips will become a disturbance to residents A roadway departure crash is a non-intersection crash which living nearby. The noise of a vehicle riding over occurs after a vehicle crosses an edge line or center line or rumble strips is comparable to that of a passing otherwise leaves the roadway. -
TAC 2003 Jughandle Final
UNCONVENTIONAL ARTERIAL DESIGN Jughandle Intersection Concept for McKnight Boulevard in Calgary G. FurtadoA, G. TenchaA and, H. DevosB A McElhanney Consulting Services Ltd., Surrey, BC B McElhanney Consulting Services Ltd., Edmonton, AB ABSTRACT: A functional planning study was initiated along McKnight Boulevard by the City of Calgary in response to the growing traffic and peak hour congestion routinely experienced along the corridor. The objective of the study was to identify and define, the most suitable improvements for medium term (2015 horizon) and long-term (2038 horizon) traffic demands, while conforming to a large number of independent constraints. Numerous alternatives were identified, and in due course rejected, due to their inability to adequately address the project requirements or satisfactorily meet stakeholder needs. Ultimately, a conventional intersection design involving widening along the south side of the corridor and the jughandle intersection concept were short listed for further evaluation and comparison. These design alternatives were subjected to a relatively rigorous appraisal that included performance, signing, laning and signalization requirements, property impacts, access and transit requirements, safety considerations, human factors and environmental impacts to name a few. It was found that operationally, the jughandle intersection design has compelling application potential in high volume corridors where local access is required and full grade separation is impractical or too costly. However, the jughandle property acquisition requirements and resulting costs along highly urbanized corridors, combined with their limited implementation experience in North America, can preclude their use in less than optimum circumstances. 1. INTRODUCTION Arterial roadways are typically designed and built with the intention of providing superior traffic service over collector and local roads (1). -

Draft Transportation
Sturbridge Master Plan 2010 (DRAFT) February 2011 7 Transportation Introduction Positioned at the junction of two major Interstate highways, I-84 and I-90, Sturbridge has excellent regional access to major urban areas. This regional interstate proximity brings benefits in terms of convenient access but also brings high traffic volumes and speeds, which compromises pedestrian, bicyclist and driver safety. For this reason, the location of Sturbridge at the junction of I-84 and I-90 is considered to be both a strength and weakness in terms of transportation and land use balance. In addition, Sturbridge’s Main Street, Route 20, is a state-owned roadway. The 1988 Sturbridge Master Plan identified traffic as one of Sturbridge’s most pressing issues. During the public outreach efforts for this Master Plan, Sturbridge residents reiterated similar transportation-related themes from the 1988 Master Plan including: Develop an identity and sense of arrival into Sturbridge through the creation of distinct gateways and streetscaping, especially given the number of tourists coming to the area; Balance the need to facilitate traffic flow with desires to make the roadways more walkable and bikeable; calm vehicle traffic speeds where appropriate (especially through the Commercial Tourist District (CTD) along Route 20); Eliminate sign clutter and improve wayfinding to the key destinations; Ensure that paratransit service meets the expanding needs for elderly and disabled residents; and Make public transportation more available. Over the last 30 years, Sturbridge has experienced rapid residential growth. The population is expected to continue to increase due to the availability of land, the relatively low cost of house lots, and the proximity and access to major highways. -

Supplementary Notes Research performed in cooperation with the Texas Department of Transportation and the U.S. Department of Transportation, Federal Highway Administration. Research Project Title: Safety Measures for Rural Intersections 16. Abstract Studies were conducted on left-turn behavior, left-turn lane guidelines, and in-lane rumble strips. Behavior on the major road at a T-intersection is influenced by the width and type of the shoulder. When a wide level shoulder was provided, a large percentage of the drivers, up to 95 percent, drove on the shoulder at speeds near the operating speed of the roadway. At the site where the shoulder was retrofitted using available materials and widened from 3 ft (0.9 m) to 10 ft (3.1 m) just prior to the intersection, only 19 to 29 percent of the drivers used the shoulder. -
