Evaluating the level of service (LOS) of bicycle lanes is essential in planning, designing, and maintaining bicycle infrastructure. This study presents a new concept—the cyclist domain—for characterizing interactions between cyclists and proposes a cyclist-domain-based method for evaluating the LOS of bicycle lanes. Unlike conventional bicycle lane LOS evaluation method, which counts the weighted events numbers and may generate inaccurate results and even misleading decisions, we specified four types of overlapping cyclist domains to characterize potential impacts in various riding events. The cyclist domain influence ratio (CDIR) derived from cycling trajectories is used to measure the negative impact between cyclists. We then propose an LOS evaluation method for bicycle lanes based on CDIRs. The user comfort is defined as the sum of products of CDIRs and respective durations. The bicycle lane LOS is then evaluated by the average comfort of all users. The case study shows that the proposed method can efficiently and effectively evaluate the bicycle lane LOS.

Grounded Theory Approach

Protected bicycle lanes are held up as the end-all of bicycle infrastructure, with unprotected bicycle lanes being widely considered unsafe and inferior. This perspective is supported by existing research showing people’s preference for protected versus unprotected bicycle lanes. Scant research, however, has explored this topic area using an observational research method. If an observational method is used, the research is typically count-based and focused on a predetermined sets of variables identified before the observation period and this hinders the research from advancing findings beyond frequencies and the already known variables. Without a clearer understanding of how people are using and interacting on streets with either type of bicycle lane, it is difficult, if not impossible, to adequately assess whether, and which, facility type best accommodates safe bicycle mobility. This paper introduces a new qualitative-quantitative method for conducting observational research which takes a grounded theory approach to gain new insights into how people behave and interact while using street segments, intersections, and other public places. This method follows a four-step process which involves qualitatively identifying interactions recorded on video, using deductive and inductive logic to document independent variables associated with interactions, and concludes in a quantitative analysis of the qualitatively produced data. As a display of the applications of this method, a case study is presented here which uses the new method to investigate the interactions of bicyclists with other road users on a street segment with an unprotected bicycle lane in Munich, Germany.

The article presents the relationship between the intensity of bicycle traffic volume and the development of bicycle infrastructure on the example of Warsaw. There has been a big increase in cycling over the last decade. At the same time, the linear and point bicycle infrastructure developed very strongly. Similar trends are also observed in other cities in Poland. The article presents the types of infrastructure available to cyclists. Then, the method of assessing the bicycle infrastructure is presented, taking into account the five features of good bicycle infrastructure: cohesion, directness, attractiveness, safety and comfort. In terms of coherence, the analysis covered the bicycle infrastructure network in the vicinity of the measurement site. The directness was tested by checking the accessibility of several dozen of the most important nodal points of the city's communication network. The attractiveness was examined by checking the availability of public bike stations, bicycle racks and bike-sharing stations. The infrastructure adjusted to the technical class of the road was adopted as a measure of safety. The comfort was checked by analyzing the quality of the road surface, which affects the driving comfort and energy expenditure. All the factors presented impact the cyclist's assessment of the infrastructure. To standardize the assessment rules, an aggregate index of the development of bicycle infrastructure was determined. The analysis was carried out for 10 sample points for four consecutive years. The points were characterized by different bicycle infrastructure, location in the city road network and different results of bicycle traffic measurements. The analysis showed a strong positive relationship between traffic and cycling infrastructure for most of the analyzed places. There was a negative dependence in the case of the construction of alternative routes in relation to the place of traffic measurements. The obtained results are the same as in the works of other authors. However, the effects of work do not allow to determine which of the examined factors is the cause and which is the effect but only show the existing relationship.

This paper examines the impacts of bicycle infrastructure on business performance in San Francisco, CA. The purpose of the paper is to provide better information about the potential impacts of bicycle infrastructure on different types of business, thereby improving the planning process and providing more confidence in outcomes for stakeholders. The analysis uses secondary data on business employment and sales to measure the change over time in performance of businesses abutting a bicycle lane intervention, versus the performance of nearby but non-abutting businesses. The paper finds that bicycle lane interventions in San Francisco rarely produce profoundly negative outcomes, and that they are often associated with positive business performance outcomes. It also finds that different types of businesses experience bicycle lane interventions differently, with the implication being that transportation planners need to understand and carefully account for the mix of businesses in implementation sites.

First Time

Cycling has become a popular, resilient and reliable travel option during the pandemic in cities around the globe. The implementation of emergent, or pop-up, bike lanes has received an overwhelming response since early 2020 and has also created a growing desire for safe and efficient bicycle infrastructure. Between March and July 2020, 394 cities, states and countries reported interventions that reallocated street space for people to cycle and walk more easily, directly and safely. This shift to cycling comes at a perfect time when cities have been making efforts to meet greenhouse gas emissions reduction targets. Pop-up bike lanes are typically implemented with temporary materials to segregate a traffic lane for the use of cyclists only. Despite this initial temporary condition, any new cycling infrastructure must be designed and implemented thoughtfully and to the highest standards to reduce or eliminate risks that cyclists face during trips, especially novice cyclists who might be biking in the city for the first time. When a crash occurs between a vehicle and a bicycle, it’s the cyclist who is most likely to be injured. According to the WHO, every year 41,000 cyclists die in road traffic-related incidents worldwide, representing 3% of global road traffic deaths. Temporary and quickly designed bike lanes should not compromise on safety. Bike lanes that are deployed now may have a significant impact on travel patterns and safety in cities for years to come, especially as the broad range of temporary materials available can be rapidly installed yet offer a semipermanent solution. For this reason, it is important to get the design and planning right. And right means safe. This guidance equips government agencies, designers, and civil society organizations that are participating in the health crisis response with an understanding of how to protect cyclists through safe and appropriate design. Cities are investing considerable effort and resources to implement safe cycling lanes under very challenging conditions, and this energy should not be wasted. The guidance provided here is based on the broad experience of the global team of authors, led by the WRI Ross Center for Sustainable Cities in collaboration with the Dutch Cycling Embassy, the League of American Bicyclists, Urban Cycle Planning (Denmark), and Asplan Viak (Norway).

For cities wishing to foster a strong culture of cycling, developing a network of safe and efficient bicycle infrastructure is paramount, yet not a straightforward task. Once transport professionals have selected the optimal location for a new bicycle facility, determining the optimal facility type is imperative to ensure that the new infrastructure encourages cycling trips and increases the safety of cyclists. The present study presents a nuanced approach to evaluating cyclists’ usage of various types of bicycle facilities. To achieve this goal, we employed survey data of cyclists in Quebec City, Canada, to study how many cyclists reported using a particular bicycle facility in the survey against their reasonable access to those reported facilities. To account for different preferences, behavior, and motivations among cyclists, we segmented our study sample into six types of cyclist. Finally, regression modeling was employed to predict the stated usage of three facility types present in the study area (recreational path, bi-directional protected lane, and painted lane), while controlling for access to this path, cyclist type, and personal and neighborhood characteristics. Results indicate that if a cyclist has access to each facility type on their commute, they are most likely to use a recreational path on their commute, followed by a painted bicycle lane. Respondents with access to a bi-directional lane are no more likely to report using this facility than respondents without access. Overall, this study is intended to encourage a dialog between cyclists and transport practitioners to uncover the factors contributing to effective bicycle infrastructure.

AbstractAn innovative approach towards transformative change through multi-stakeholder participation for socio-ecological practices—Integrated Local Delivery (ILD)—has been used to restore the water quality and biodiversity across a catchment in the Cotswolds, South West England. This was triggered by the need to improve the Ecological Status of water as a part of the European Union’s Water Framework Directive. On a landscape scale of roughly 25,000 hectares, multi-stakeholders collaborated through a bottom-up approach to carry out environmental restoration of the catchment.Over 3 years, an iterative learning loop of reflection and evolution created increased engagement. Twenty farmers have been empowered as ‘guardians’ to be key contacts between institutions and ensure the sustained environmental quality of the area. Both farmers and communities acted to reduce chemical use, protect river banks from livestock damage and clear waterways to enhance water quality and biodiversity. Local communities fed into the development of a ‘Community Water Guide’ which can be applied internationally for similar projects. Within the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) transformative change framework, the ILD model can also be applied by facilitators to access levers and leverage points in order to enable change.Important take home messages from the project include having well-trained facilitators who ensure active engagement, connections and continuity over the long term. Likewise, ensuring all stakeholders feel listened to and clearly communicated with is essential to build trust and motivation.
