Saddle height positioning for triathletes ssing road cyclist methods
… used for determination of height for road cyclists. It has yet to be determined if these methods are applicable to triathletes. Because of the different geometry of a triathlon bicycle, the question remains whether road-saddle fitting techniques can be an applied and work for the triathlon …

A Cyclist Detection and Tracking System for Heavy Goods Vehicles
Summary Thesis title: A Cyclist Detection and Tracking System for Heavy Goods Vehicles Author: Yan KE Heavy Goods Vehicles (HGVs) contribute to a large portion of collisions with cyclists, and a disproportionate number of these are caused by construction vehicles. Among all these collisions, the …

Completing the Network: Exploring Cyclist Desires and Advocate Priorities for Bicycle Parking
… advocacy objective and the second determines how cyclists in New Orleans perceive bicycle parking. At the most narrow geographic scope an observation of bicycle parking patterns is completed on Magazine Street in New Orleans. The thesis finds that bicyclists desire bicycle parking and that bicycle …

A petri net based model for AEB systems considering vehicle and pedestrian/cyclist in a certain area
… scenarios with different variables which include cyclist speed, vehicle speed, cyclist moving directions, and so on. There are several braking patterns described in this thesis, which provide the possibility to control the distance of an emergency braking. With different braking distance and …

Street-level air quality : exploring the feasibility of a cyclist-led, crowdsourced map in Singapore and Mexico
… creating a street-level air quality map, whereby cyclists gather data through a participatory sensing process as they ride around the city. I explore two primary areas required for the successful creation of such an initiative: the state of the technology for portable air quality monitors, and the …

Energy methods for analyzing drag and inertia in cycling kinematics
… measuring the drag and effects of inertia for a cyclist during a race. Professional cyclist data from the Tour de France was acquired for several athletes. The data contained elevation, distance, velocity, and power as a function of time. Rolling resistance, drag, inertial energy, and potential …

Utvärdering av cykelfälts effekter på cyklisters säkerhet och cykelns konkurrenskraft mot bil
… an evaluation of bicycle lane effects on cyclist safety and the ability of bicycles to compete with car traffic. Thirteen Swedish urban streets were studied before and after bicycle lanes were introduced. Data was collected using video recordings, speed studies, road side …

Revealing challenges and opportunities in cycling safety through crowdsourcing
… these needs, which are also of interest to cyclists and policy makers, are currently not being met satisfactorily. In this thesis, we present three main contributions to solve these problems. First, we show SimRa, a crowdsourcing-based citizen science project to record cycling trips and near …

Characterizing Bicyclists Behavior in Overtaking Scenarios Over Different Road Infrastructures
… have increased in the United States while cyclist crashes often go unreported. The underreporting of all cyclist crashes results in the overall pre-crash behavior of the cyclists being unknown. What is known is that the most fatal bicycle crash scenario occurs when a vehicle performs an …

Assessing the Efficacy of Bicycle Helmets in Reducing Risk of Head Injury
… protection. However, the conditions surrounding cyclist head impacts are thought to be much more complex than the test conditions prescribed in standards and have important implications related to mechanisms of injury. The overarching aim of this dissertation was thus to investigate the …

Investigating Violation Behavior at Intersections using Intelligent Transportation Systems: A Feasibility Analysis on Vehicle/Bicycle-to-Infrastructure Communications as a Potential Countermeasure
… for crashes resulting from drivers' and cyclists' violations at intersections. The characteristics (e.g., acceleration capabilities, etc.) of transportation modes affect the violation behavior. Therefore, the first building block is to identify the users' transportation mode. …

Street typology and bicyclist safety : a systems approach
… perceived as dangerous. Much literature on cyclist safety and the built environment has focused on bicycle facilities such as bike lanes, while fewer studies have addressed route choice, specifically side streets versus arterials. The cities of Berkeley, CA and Cambridge, MA have pursued …

Optimizing cycling power
… was successful as verified by ride data from a cyclist in the 2014 Tour de France. Additionally, the model was further tested with sample power profiles in order to understand the depletion of energy over the course of a ride. Two key findings emerged from the investigation. First, we require a …

Evaluating the Impact of Access Density on Pedestrian and Bicycle Safety
… on vulnerable road users such as pedestrians and cyclists.</p> <p>To quantify these impacts, this study identified high-crash roadway segments using Florida Department of Transportation (FDOT) data. Geometric, traffic, crash, and access management information was collected and analyzed across 133 …

A Comparison Between Two Oblique Test Protocols for Cycling Helmets
… The CEN proposed standard may represent a cyclist falling vertically onto a curb, angled surface or motor vehicle. The ALI represents a cyclist skidding or falling over the handlebars and have been described as frequent-accident cases in the literature. Both protocols represent unique …

Product design and development of an aerodynamic hydration system for bicycling and triathlon
… are both essential needs of a competitive cyclist or triathlete. Several aerodynamic systems have been developed for use on bicycles but few have been designed to be truly aerodynamic or easy to use. This project focused on the design and development of a frame mounted hydration system for …

Pacing strategy optimization for time trial cyclists with physiological constraints
… optimization of pacing strategies for time-trial cyclists by integrating physiological constraints with course-specific environmental factors. Two complementary methods are developed: one directly optimizes velocity profiles using total energy expenditure as a proxy for current energy, while the …
