Innovative Treatment for Pinch Points

This project aims to review existing practice, re-measure the effectiveness of Bicycle Activity Zones, deploy and evaluate dynamic warning sign technology, develop guidelines for treating pinch point locations and provide recommendations for the way forward.

Aging Road User, Bicyclist, and Pedestrian Safety

In task 1 of this report drivers' knowledge of various bicycle warning signs and pavement markings were assessed.  In task 2, a simulator study was used to explore whether differences in comprehension/recognition/legibility had an impact on driver behavior. Drivers navigated a simulated route in which they passed bicyclists riding singly or in groups. Sometimes bicyclists were located within a bike lane, and sometimes a bike lane was not present. Drivers first completed a gap judgment task in the driving simulator. Participants also drove a simulated route and were asked to make turns at intersections featuring a minimal or large negative offset.

China Shows Leadership in Bike Share and Greenways

This article describes how cities in China are embracing bicycle sharing systems and the establishment of greenways in order to improve mobility and quality of life.  The first bicycle sharing system in China was opened four years ago. Since then cities have established a variety of high-tech systems that include automated docks operated with smart cards and bicycles with direct drive pedals. Chinese cities are also implementing greenways and promoting them as walking and bicycling networks as well as public space. More than 6,000 km of greenways have opened in the past two years, and another 14,000 km are in the planning stage.

Counting Bikes on London’s Cycle-Only Street

Bicycle counters with visible feedback are being used on a cycle-only London street to encourage bicycle users and build solidarity in the bicycle community.  Hackney Council commissioned a bike counter on their bicycle-only street, Goldsmiths Row, at on Monday, August the 5th.  Just 15 days later and it has already seen over 69,000 people on bikes have ridden past.  The feedback helps bicycle users to feel less alone and more of a large community by communicating data that shows how many people are riding.

Reallocation of Road Space

This report examines traditional usage of "road space" and questions some of the basic assumptions about what conditions result in an effective transport corridor.

Road safety and bicycle usage impacts of unbundling vehicular and cycle traffic

This paper looks in detail at the implications for safety and cycling participation of "unbundling" the bicycle and motor traffic networks.  "Unbundling" is measured as the degree to which bicycle networks are separated, particularly in higher speed/traffic distributor roads.

Going Dutch? Berkshire site tests Netherlands cycling model

This research is being done to determine what features of Dutch-style bicycle infrastructure can be adopted by Transport for London.  Dana Skelley, director of roads for TfL said, "Pretty much everything here is a layout that we're not permitted to have on national roads under the current legislation. We realised that if we wanted to attract more people to cycle, more safely and more often, it was necessary to create a more cycle-friendly environment, and we looked towards Europe for that."

Demystifying Signalized Intersection Design for Bicyclists

This paper suggests a set of cost-effective techniques that can be applied at signalized intersections to significantly improve bicycle comfort, efficiency, and safety. Bicyclists'’ unique characteristics, including slower acceleration and operating speeds than motor vehicles, often require specific adjustments to signal design. Specialized signal-design techniques include bike signals, leading bike intervals, separate bicycle phases, and detection methods. Beyond signal adjustments, additional physical design treatments can be utilized such as bicycle lanes, cycle tracks, bicycle boxes, and turn pockets at signalized intersections.

Assessing Bicycle Delay at Signalized Intersections

This study utilises a conceptual model to assess bicycle delays at signalised intersections. The model incorporates approach traffic volume, adjacent traffic speed, and easy to obtain signal timings from Synchro traffic models to determine bicycle delay for left turn, through, and right turn movements.

Bicycle Parking Regulations for Multi-Unit Residential Buildings in Toronto

This paper describes a research program undertaken by the City of Toronto to provide an empirical basis for updating bicycle parking regulations in the City's zoning bylaw. Using data from travel surveys and a targeted survey of bicycle owners in recently-constructed multi-unit residential buildings, the research determined the current demand for bicycle parking in different areas of the city, and the effectiveness of existing regulations in meeting the bicycle parking needs of residents.
