“…For a single ride, it is enough to provide a minimum width. By the experimental results in [21], the required lane width was approximately 2.0 m when the speed of a bicycle varied from 10 km/h to 30 km/h, and it was concluded that 3.0 m exceeded the required width. The results recommended 2.0 m as the minimum safe width for a bike lane with no curb or gutter.…”

“…Lee et al used precise GPS instruments to measure bicycle trajectories on a bicycle lane without curbs. Based on the results of their study, a bike lane width should be at least 2.0 m to allow for rider stability on roadways with no curb or gutters [21]. Fees et al tested the impacts of a buffer, bicycle lane width, vehicle mix, and on-street parking on bicycle operation.…”

The paper aimed to develop width recommendations for separated bicycle lanes considering abreast riding and overtaking behaviors. We investigated eight segments of separated bicycle lanes in Nanjing with cameras, analyzed the major types of abreast riding and overtaking, and then explored the volume threshold for two-abreast riding as well as the suitable clearances in a comfortable overtaking, using a binomial logistic model for both. The main results and conclusions are as follows: (1) two-abreast riding and an electric bicycle passing a conventional bicycle were the main categories of abreast riding and overtaking, respectively. (2) The volume threshold at which two-abreast riding occurred was 1075 bicycles/h/m. (3) Distances of 0.48 m, 1.48 m, and 0.56 m were the suitable clearances for the distance from the center of the passed rider to the nearest curb, the distance center to the center of riders while overtaking, and the distance from the center of the passing rider to the nearest curb, respectively. (4) Below 1075 bicycles/h/m, a bicycle lane 2 m in width was acceptable; above that, 2.5 m was suggested as the minimum width of the bicycle lane.

“…Several previous studies focused on the measurement and analysis of speed of cyclists in different route configurations, e.g., urban trials used by hikers, cyclists and joggers (Virkler & Balasubramanian, 1998), public roads (Akira, et al, 2012), roundabouts , and signalized intersections (Lee, et al, 2011;Lucas & Kanade, 1981). Knowledge of cyclist speed can be important in the following contexts:…”

“…The safety of cyclists is becoming a national and a worldwide concern. For example, Transport Canada reported that across Canada, 60 cyclists were killed in traffic Several previous studies focused on the measurement and analysis of the speed of cyclists in different route configurations, e.g., urban trails used by hikers, cyclists and joggers (Virkler & Balasubramanian, 1998), public roads (Akira, et al, 2012), roundabouts , and signalized intersections (Lee, et al, 2011;Lucas & Kanade, 1981).

“…Video monitoring is less susceptible to the impact of tall physical objects, (e.g., highrise buildings that abound in urban environments as compared to traditional GPS tracking techniques). Note that sophisticated GPS technologies which provide highaccuracy in urban canyons, such as real-time kinematic (RTK GPS)(Lee, et al, 2011), require much more complicated set-up preparations than the computer vision technique presented in this study.2. Monitoring movements of road users are non-intrusive and will likely result in analyzing naturalistic cyclist movements.…”

Innovative Techniques for Analyzing Cyclist Behaviour and Predicting Cyclist Safety

Cycling is an important mode of travel which offers powerful solutions to chronic traffic problems of congestion and emissions. Therefore, it is imperative for the road designers to have reliable information on the cyclist behaviour and characteristics to design safe and efficient cyclist facilities. The behaviour of the cyclist can be measured in different ways, including, cyclist crossing speed, cyclist violations, and cyclists-vehicle interactions.The essential focus in this thesis was on cyclists, especially their speed measurement and analyzing cyclist-vehicle interactions. In this thesis, a reliable video analysis technique to measure cyclist speed at signalized intersection was developed. This technique enables the automated observation of large volume of naturalistic cyclist movements in an accurate and resource-efficient manner.As for cyclist safety, relying solely on collision records to analyze cyclist safety is challenged by inherent limitations in collision data. These limitations can be quantitative and/or qualitative. Traffic conflict techniques have been used as a proactive and integrated approach to collision-based road safety analysis. However, traditional traffic conflict studies are mostly field-based studies and due to the subjectivity of field observers, errors were common when manually counting and deciding/judging whether a given traffic event is a conflict. In this thesis, interactions between motor vehicle and cyclists at signalized intersections were characterized using an objective conflict indicator; Post-Encroachment Time (PET).The thesis also produced a sizeable database of 806 hours of video data for cyclist movements. A total of 19,058 cyclists and 48,632 vehicles were observed within a total

Cycle track design guidelines are rarely based on scientific studies. In the case of off-road two-way cycle tracks, a minimum width must facilitate both passing and meeting maneuvers, being meeting maneuvers the most frequent. This study developed a methodology to observe meeting maneuvers using an instrumented bicycle, equipped with video cameras, a GPS tracker, laser rangefinders and speed sensors. This bicycle collected data on six two-way cycle tracks ranging 1.3-2.15m width delimitated by different boundary conditions. The meeting maneuvers between the instrumented bicycle and every oncoming bicycle were characterized by the meeting clearance between the two bicycles, the speed of opposing bicycle and the reaction of the opposing rider: change in trajectory, stop pedaling or braking. The results showed that meeting clearance increased with the cycle track width and decreased if the cycle track had lateral obstacles, especially if they were higher than the bicycle handlebar. The speed of opposing bicycle shown the same tendency, although were more disperse. Opposing cyclists performed more reaction maneuvers on narrower cycle tracks and on cycle tracks with lateral obstacles to the handlebar height. Conclusions suggested avoiding cycle tracks narrower than 1.6m, as they present lower meeting clearances, lower bicycle speeds and frequent reaction maneuvers.
