“…This issue is associated with the need for research assessing which assumptions can be adopted for e-bikes from those related to bicycle-pedestrians interactions. Research in respect to BLOS studies is mostly based on transport components, including segments [91,[167][168][169][170][171][172], nodes [63,[173][174][175] and networks [5,[176][177][178][179]. However, network-based BLOS studies compared to link and node studies require more extensive research [180][181][182][183][184].…”

Research into the bicycle level-of-service (BLOS) has been extensively conducted over the last three decades. This research has mostly focused on user perceptions of comfort to provide guidance for decision-makers and planners. Segments and nodes were studied first, followed by a network evaluation. Besides these investigations, several variables have also been utilized to depict the users’ perspectives within the BLOS field, along with other cycling research domains that simultaneously scrutinized the users’ preferences. This review investigates the variables and indices employed in the BLOS area in relation to the field of bicycle flow and comfort research. Despite general agreement among existing BLOS variables and the adopted indices, several important research gaps remain to be filled. First, BLOS indices are often categorized based on transport components, while scarce attention has been paid to BLOS studies in trip-end facilities such as bicycle parking facilities. The importance of these facilities has been highlighted instead within research related to comfort. Second, the advantages of separated bike facilities have been proven in many studies; however, scarce research has addressed the challenges associated with them (e.g., the heterogeneity within those facilities due to the presence of electric bikes and electric scooters). This issue is clearly noticeable within the research regarding flow studies. Furthermore, network evaluation (in comparison to segment and node indices) has been studied to a lesser extent, whereas issues such as connectivity can be evaluated mainly through a holistic approach to the system. This study takes one step toward demonstrating the importance of the integration of similar research domains in the BLOS field to eliminate the aforementioned shortcomings.

“…Although the analysis procedure for arterials was updated in the sixth edition of the HCM [15] following the work from Dowling et al [45], two-lane and multilane highways methodologies remained unchanged in the subsequent HCM editions [15,16]. Other researchers and agencies adopted the US HCM-LOS concepts to their local conditions [8,12,[46][47][48][49], or validated the LOS approach with empirical image data [37,45,50], video and bicycle simulator data, [51] or with practitioner opinions [52].…”

Cycling on rural highways presents comfort and safety concerns due to the large speed differentials between bicyclists and automobiles. A shortcoming of the current operational methods for rural highways is the limited consideration of quality of service for non-motorized users. This research aims to determine which variables are most relevant to bicyclists cycling (or not) on rural highways and their operational cycling preferences. An online survey collected 982 responses from individuals who cycle on rural highways in the United States. Eight choice tasks were presented with six factors: pavement quality, automobile traffic level, posted speed limit, roadside design, context class, and grade. These factors were obtained from a preliminary survey targeting highway analysis and design practitioners. The results of a mixed-logit model analysis suggest that the presence of a shoulder and its width are the most critical factors to a cyclist's perceived quality of service on a rural highway. We found that the difference between rural-town and suburban contexts was minor compared to rural contexts. The results demonstrate how cyclist types influence their overall willingness to cycle and their preferences for scenario-specific attributes. This opens the discussion to include different sets of thresholds to assess service levels as a function of cyclist type, following the level of traffic stress approach, and separate perception models by cyclist type. These results should inform recommendations for future research on improving existing evaluations related to bicycling on rural highways.

“…Bicycle level of service (BLOS) was strongly influenced by side path separation (β=0.605, p<0.05); vehicle speed (β=0.717, p<0.05); motorized traffic volume (β=-0.381, p<0.05); and conflicts with pedestrians (β=1.173, p<0.05). Similarly, (Okon & Moreno, 2019) filmed segments for 20-40 seconds during bicycle rides at a speed of about 5km/h with a camera strapped, at an angle of 45 degrees, on the head, which was subsequently rated by respondents. Curb lane variables such as bicycle pathway widths, curb lane motorized volume (veh/h) and vehicle speed (km/h), bicycle volume on the segment, and median width was recorded in addition to secondary data.…”

“…It is an extension of ordinal least-squares regression that generalizes linear regression and thus allows the linear model to be related to the response or dependent variable (in our case the overall rating of segments/intersection). It is a multinomial probability distribution with cumulative logit as link function (Okon, et al, 2017;Okon & Moreno, 2019).…”

Purpose of the study: A satisfaction audit for use of cycling mode is aimed at the promotion of non-motorized transport which is safe, comfortable, economical and energy-efficient as critical for urban sustainability. The study examined the level of satisfaction that cyclists derive from the cicloruta based on the intersections in the network. Methodology: The methodology involved the use of primary data such as 680 perceptions of satisfaction ratings; physical and operational characteristics of road infrastructure (measurement and observational) data; and shapefile of the cicloruta. The relationship between variables was examined using correlation statistics, while the ordered probit model was used to estimate the parameter, predicted logit and predicted probabilities. Main Findings: An estimated model for intersection bicycle level of service (IntBLOS) revealed that the volume of vehicular and total intersection legs are factors with a high influence on cyclist’s level of satisfaction. The model was used in ArcGIS to compute IntBLOS scores at both segment and facility levels. Since segments are not independent of intersections or vice versa, the study used these two independent models to estimate the level of bicyclist’s satisfaction. Applications of this study: This study undoubtedly takes a step towards demonstrating a non-motorised transport infrastructure audit which can help address specific concerns of cyclists and thus enhance ridership in the study area. Elsewhere, especially in the developing countries applicability of this methodology shall be with modifications on measurement and observation data that reflects peculiar local traffic situations. Novelty/Originality of this study: The findings of this paper has stimulated further conversation on the factors of cycling in the city with its ambitious cycling infrastructure. It has also provided planners with an infrastructure audit methodology to enhance cycling safely and sustainably. The study recommended proper enlightenment of motorists and cyclists alike on their right of way and most importantly, the redesign of most intersections in the study area to reflect the present cycling realities of Bogota.
