“…maximum likelihood estimation (MLE) of the regression statistics to estimate models of bicycle and pedestrian traffic in Minneapolis. Similarly, Providelo and da Penha Sanches [1] used the method of successive intervals to define traffic characteristics based on priority of users and potential users to evaluate bicycle infrastructure in Brazilian medium-sized cities. These and other studies form the background for our choice of analytical techniques.…”

“…Among others, cycling has the potential to reduce intra-urban problems that result from the dominance of motorised urban transport [1]. These problems include, traffic congestion, noise, accidents or outright death, urban air quality degradation and high energy consumption.…”

“…From the user's perspective, Kang and Lee [4] similarly developed a bicycle level of service (BLOS) model for South Korea using 'facility, operation, intersection and safety characteristics'. On the other hand, Providelo and da Penha Sanches [1] used successive interval analysis to develop a level of service (LOS) for a medium-sized Brazilian city that described the level of satisfaction from bicycle infrastructure. And in their 'real-time human perceptions' study of American cities towards a bicycle level of service, Landis et al [7] mathematically expressed basic traffic conditions for road segments that influence bicyclists' level of service perception.…”

Understanding the perception of level of service (LOS) of cyclists can be useful in developing a planning strategy for promoting intra-city bicycle commuting. In Bogota, the enormous resource investment in the Cicloruta system requires a regular infrastructure audit to ascertain its level of performance. Videos of 16 segments and 8 intersections were carefully collected and showed to participants who rated their level of satisfaction using a 6-point scale (A-F -'highly satisfied' to 'highly dissatisfied'), equivalent to 1360 segments and 680 intersections (2040 total ratings). The perception data was augmented with geometrical, physical and operational characteristics of traffic in the area. Most participants fall within ages of 18-35 in both male (88.9%) and female (77.4%) while bicycle ridership also revealed more riders in male (75.9%) than in female (58.1%). The study showed that 69.4% of participants ride bicycles in the city while 30.6% do not. Ordered probability models were used to estimate random parameters of cyclists LOS perception to account for unobserved heterogeneity for all respondents. 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); motorised traffic volume (β=-0.381, p<0.05); and conflicts with pedestrians (β=1.173, p<0.05). Furthermore, other factors were also found to have high probabilities to influence LOS including bicycle lane width, wide outside lane, pavement conditions, trees and benches, daylight, gender and the experience of the cyclist. A model for intersection LOS was estimated, the results of which results reveal that the volume of cyclists (β=1.116, p<0.05), conflicts with pedestrians/other cyclists (β= 1.048, p<0.05) and total intersection legs (β=-0.365, p<0.05) are factors with a high influence on cyclist's LOS. The variety of factors affecting bicyclists reveal the nature and character of urban transportation in Bogota and suggest a range of important recommendations such as education and public enlightenment of cyclists and motorists, in further planning and management of the Cicloruta. Keywords: bicyclist, segment bicycle level of service, intersection bicycle level of service, ordered probit models, Cicloruta.

“…Apart from the registered demand, space availability and appropriate cycling infrastructure are basic prerequisites for the development of cycling traffic. According to previous studies [3,4], attributes which define a quality cycling infrastructure are: a roadway's physical, functional and operational characteristics (lane width, design speed, manoeuvring space, existence of sharp turns and obstacles), motor vehicle speed, intersection sight distance, presence of intersections and street trees (shading). Advantages, disadvantages, and experiences of cities and countries under development, implementation and evaluation of cycling traffic policy and program measures are demonstrated in detail by Pucher et al [1].…”

“…So, the main purposes of this paper are: (1) study, describe and analyse the current state of cycling traffic; (2) list and describe implemented policy and program interventions to promote cycling; (3) show on where and to what extent these interventions are currently being implemented; and (4) assess the actual impacts of various interventions on the level of cycling in Zagreb. For this purpose, a comprehensive search of relevant and available literature has been made.…”
