“…However, some informal separation could be added, for example, using a small strip of cobbles to separate the motorized traffic lanes [65] and coloring of the on-street cycling lanes to form a distinct demarcation [62]. These types of separation should also be complemented by a reduction of motor traffic speed, which could increase people's reaction time and increase perceived safety [66].…”

Cycling is gaining increasing attention as a convenient, environmentally friendly, and fitness-improving mode of transport. While many policy interventions have been made to promote cycling, not enough research has focused on the barriers to implementing pro-cycling policies. For effective policy implementation, identifying major barriers and removing them is critical. This study took an in-depth look at Hamburg which started a major cycling promotion in 2008. According to expert interviews and literature surveys, the author found that the major barriers are physical, political and institutional, and social and cultural. Specifically, the city lacks enough physical space, political support, and the evaluation of travel behavior and demand. Also, some private stakeholders are reluctant to give up on-street car parking space for cycling lanes, and the negotiation process is difficult and time-consuming. To overcome these barriers, Hamburg requires cycling-oriented urban design, a strategic and integrated cycling action plan, strong political support, and target group-oriented communication.

“…As a healthy and environmentally friendly transportation mode, cycling has become more and more popular in the United States (US) over the past two decades [1]. Previous research has indicated that cycling can provide substantial individual health benefits and alleviate negative impacts of motorized transportation, such as congestion and pollution [2][3][4][5]. Promoting the development of cycling could clearly benefit the social, environmental, and economic sustainability [6].…”

Hit-and-run (HR) crashes refer to crashes involving drivers of the offending vehicle fleeing incident scenes without aiding the possible victims or informing authorities for emergency medical services. This paper aims at identifying significant predictors of HR and non-hit-and-run (NHR) in vehicle-bicycle crashes based on the classification and regression tree (CART) method. An oversampling technique is applied to deal with the data imbalance problem, where the number of minority instances (HR crash) is much lower than that of the majority instances (NHR crash). The police-reported data within City of Chicago from September 2017 to August 2018 is collected. The G-mean (geometric mean) is used to evaluate the classification performance. Results indicate that, compared with original CART model, the G-mean of CART model incorporating data imbalance treatment is increased from 23% to 61% by 171%. The decision tree reveals that the following five variables play the most important roles in classifying HR and NHR in vehicle-bicycle crashes: Driver age, bicyclist safety equipment, driver action, trafficway type, and gender of drivers. Several countermeasures are recommended accordingly. The current study demonstrates that, by incorporating data imbalance treatment, the CART method could provide much more robust classification results.

Bicycle for urban transportation in emerging countries still relies on “upright” bicycle which is unchanged since the 20th century. In a tropical emerging country such as Indonesia, a bicycle must be ergonomically designed because it may be used in a long run. On the other hand, bicycle rider may face various traffic conditions. Additionally, weather makes trip become heavy and takes a lot of energy. This research aims to develop and test a new bicycle concept for an urban transportation in the tropical emerging country. A multi-criteria decision method was used to select a right bicycle concept. Then the concept was detailed into a bicycle design. We used biomechanics model and simulated finite element method to verify its frame strength. After the design verified, we built a full bicycle prototype and compare it with a commercially available urban bicycle with equal specifications. The comparison tests include physiological tests and a subjective test for several terrain and traffic conditions. The new concept is an ergonomic bicycle based on rear wheel drive recumbent bike. Based on the overall test result, it can be concluded that the new bicycle concept is promising and still appropriate for the next development.
