    Modeling and Evaluation Bicycle Level of Service for Links
    (Addis Ababa University, 2018-12) Henok, Yohanes; Girma, Gebresenbet (Prof.)
    In urban parts of the world, share of bicycle mode of transport is declining due to lots of difficulties and dissatisfactions. These situations make the transportation system unsustainable in the long run. In addition to this, currently, bicycle transport system has not given more attention by the transport engineers and planers to improve the facility. These days, there is no methodology widely used by engineers and planners in Ethiopia that will allow them to determine how compatible an urban roadway for allowing efficient operation of bicycles. As efforts to make environment friendly, bicycle should have more attention towards the improvement of facilities and number of users. Therefore, lots of time and energy used to develop highly reliable Bicycle Level of Service (BLOS) model that provide the transportation professionals for a suitable technique systematically to assess the bicycle service qualities. This particular study focuses to develop new BLOS model and evaluate the performance of the bicycle transportation along the link that can used by transportation professionals and others to evaluate the capability of specific roadways to accommodate both motorists and bicyclists. Because of the geographical nature of the area and the number of bicycle user, this research selects Bahir Dar city as case study area. Thus, all data that are collected represents the desired complexity and variability in the attributes of multilane roads in city of Bahir Dar. Those data for the model development obtained and collected from questioner, recorded videos, and actual geometrical and traffic data measurements. This research helps in assessing the factors affecting bicycle level of service through links and evaluating a method to determine BLOS for links under heterogeneous traffic conditions. Moreover, the developed bicycle level of service model based on the users’ perceptions of links. This model incorporates perceived safety, comfort, and operations of the bicycle users. A sensitivity analysis carried out to understand the effects of influencing variables on the BLOS and the study identified passenger car unit has the highest influence on BLOS. Finally, the resulting model is highly reliable in its applications and has a high coefficient of determination value (R 2 = 0.972) with mean observations and provides a measure of the users’ perspective on how well a link's geometric and operational characteristics meets the satisfactions of the users.
