This study was prepared on behalf of the City of San José (California) to explore the feasibility of using recycled pavements in the construction or resurfacing of trails. The report concludes that the use of recycled materials is both financially and environmentally feasible, and the use of recycled materials in trail construction is warranted. Three types of recycled material were evaluated: recycled base aggregate, rubberized asphalt, and recycled hot-mix asphalt.

Recycled base aggregate is a cost effective material that is readily available and may have performance advantages over virgin base aggregate.
Rubberized asphalt is more costly than conventional asphalt and current availability for small scale projects is limited, but it does have performance advantages.
Recycled hot-mix asphalt is also currently difficult to procure but may in time become a more readily available material. It is more costly and appears to perform similarly to conventional asphalt.

There are possible negative environmental impacts associated with these recycled materials, primarily with regard to water quality. Potential mitigation measures are suggested in this study.

Contra Costa County Trail Design Resource Handbook

StephenMRTC — Fri, 30 Jul 2010 15:50:59 GMT

Prepared for: Contra Costa County City-County Engineering Advisory Committee and Contra Costa County Departments of Public Works and Community Development

By: Wilbur Smith Associates and 2M Associates

March 2001

The purpose of the Contra Costa County Trail Design Resource Handbook is to facilitate and ensure consistency in the design and construction of bicycle trails throughout the county. Because mobility by bicycle, either on roadways or designated bikeways, does not stop at city limits, there is a need for a consistent countywide approach.

This resource manual is intended to be a model and a reference in the design of bicycle trails for Contra Costa's nineteen cities, the County, and park districts. Cities are encouraged to reference and/or adopt this handbook, where appropriate, as part of their own Bicycle Plans and/or General Plans.

The overall objective was to evaluate the effect of a novel illuminated overhead crosswalk sign and high-visibility ladder style crosswalk markings on driver and pedestrian behavior at nonsignalized intersections in Clearwater, Florida. One aspect of the field data collection effort was to determine if pedestrians were more likely to cross where there was an illuminated overhead crosswalk sign and ladder crosswalk markings. A second aspect of the study was to determine if drivers would yield more often to pedestrians using this novel pedestrian facility. A third aspect of the study was to determine if pedestrians use more, less, or the same amount of caution as well as whether they cross more aggressively, forcing drivers to yield. Nighttime observation sessions were conducted in order to better evaluate the effectiveness of the illuminated overhead crosswalk sign.

Guidance for Installation of Pedestrian Crosswalks on Minnesota State Highways

The objective of this guidance document is to establish a step-by-step procedure to evaluate the use of various pedestrian crossing treatments. This guidance is expected to produce a crosswalk program that meets both motorist and pedestrian expectations. Recent pedestrian research studies, existing crosswalk guidelines used by other governmental agencies, manuals on traffic control devices, and state statute were reviewed in order to establish this guidance document.

Retro-Reflective Thermoplastic Pavement Striping

StephenMRTC — Mon, 26 Apr 2010 20:16:57 GMT

Trail managers seek to increase the safety of trails by improving response times by public safety staff. Trails are often developed within riaprian corridors where lighting is not permitted. It is difficult to find trail alignments within the dark natural corridors particularly from police helicopters.

To address these issues, the City of San Jose, California's Trail Program and Public Works Department developed a specification document for installation of reflectorized striping to provide police a tool to more rapidly locate trails and follow the alignment through riparian zones.

A video documenting the initial research is posted on the city's website (MOV file).

The specifications support installation of a very low-profile thermoplastic striping with very high reflectance.

Paperback; Price $95.00

California Chapter of the Association of Environmental Planners Outstanding Environmental Resources Document for 2010

Trail Planning for California Communities provides essential guidance on planning, design, construction, funding, and maintenance of trails in California. Details relevant policies, legislation, and successful projects that lend strong support and provide a variety of tools for the planning and implementation of local trails. A comprehensive guide that can be used at all stages of the trail development process.

Trail Planning is an important reference for planners, advocates, developers, and managers of trails. Topics include: the purpose and value of trails, Federal and state policies, developing trail plans, building community support, legal responsibilities, trail design, environmental review (CEQA and NEPA requirements), funding, and trail maintenance.

Webinar: Selection of Pedestrian Treatments at Unsignalized Crossings

StephenMRTC — Fri, 22 Jan 2010 18:04:17 GMT

Presented by Charlie Zegeer, Director, PBIC, and Associate Director of Engineering and Planning, UNC Highway Safety Research Center. Hosted by the Pedestrian and Bicycle Information Center.

This Livable Communities Webinar focuses on the various treatment options to improve pedestrian safety at unsignalized intersections and midblock locations. Charlie Zegeer provides guidance for making decisions in selecting such treatments as marked crosswalks, signing, raised median islands, road diets (lane reductions), rapid-flash beacons, HAWK signals, the addition of traditional traffic and pedestrian signals, and other measures.
