The conclusion from this study that the electric bike are able to meet the needs to overcome uphill road

Applied Ergonomic Design Of E-Bike With Antropometric Approach

Transportation is a tool that can be easiness for mobilities a thing or people from the place one to the othe place. Along with the times, transportation also develops. The one of transportation that developing is electric bike (e-bike). The development of electric bike is to improve the previous product, so that the electric bicycle that will produced is better than before as models, colors etc. when we make the electric bike design, the first thing that we do is ergonomic analytical so the product that will produced didn’t give long term effect as muscle injury and joint pain for the user. We use analitycal RULA for analytical ergonomi to our design electric bike. We take 31 samples use the database from Student of Industrial Engineering  Adi Buana Surabaya College. The result of the RULA value which shows the most ergonomics is at a headtube angle of 15 ° with a RULA value of 3. This shows that the design of this electric bicycle is quite ergonomic and the design is acceptable, although to be ideal in its body posture, further analysis is needed in order to obtain a better RULA valu

Investigating the mobility habits of electric bike owners through GPS data

This paper investigates the mobility habits of electric bike owners as well as their preferred routes. Through a GPS tracking campaign conducted in the city of Ghent (Belgium) we analyze the mobility habits (travel distance, time spent, speed) during the week of some e-bike users. Moreover, we propose the results of our map matching, based on the Hausdorff criterion, and preliminary results on the route choice of our sample. We strongly believe that investigating the behavior of electric bikes’ owners can help us in better understanding how to incentivize the use of this mode of transport. First results show that the trips with a higher travel distance are performed during the working days. It could be easily correlated with the daily commuting trips (home-work). Moreover, the results of our map-matching highlight how 61% of the trips are performed using the shortest path

Towards an electric bike level of service

The fast-growing market of electric bikes (e-bikes) has introduced a paradigm shift in mobility with a promise to enhance the sustainability agenda. An in-depth understanding of transport quality of service (QOS) from the e-bike rider’s perspective is a promising approach to sustain the role of the e-bike in mobility. Level of service (LOS) is a method by which to quantify QOS for different transport modes. However, to date, the knowledge on e-bike LOS (ELOS) lags far behind that on other transport modes. Therefore, the central aim of this thesis is to provide fundamental knowledge related to the development of ELOS. To address the main aim of the thesis, the travel behaviour and riding characteristics associated with e-bikes were scrutinised. Both qualitative and quantitative methods were employed to provide knowledge on the travel behaviour (strategical level) and riding characteristics (tactical level) related to e-bikes. From a strategic perspective, an extensive review of the literature was conducted to explore which transport mode LOS is applicable for developing ELOS. Based on the findings from the state of the art and the reviewed literature, bike LOS (BLOS) was deemed substantial for the development of ELOS. Thus, to move towards the development of ELOS, a set of studies was conducted to understand the comfort concerns of e-bike riders via the literature review, interviews and a field experiment. Based on the reviewed literature, it appears evident that research related to the travel behaviour of e-bike users is sparse and that the scale of e-bike substitution for other modes of transport is unclear. The findings of the aforementioned study led to the proposition of a preliminary theoretical framework for the development of ELOS and served as a roadmap for conducting the studies that followed. To provide a deeper understanding of the travel behaviour related to e-bikes, a qualitative study was conducted to explore e-bike users’ (riders) and nonusers’ comfort concerns. This study was extended to include the comfort and health concerns of e-bike users and nonusers in the unprecedented COVID-19 pandemic situation. The findings of this study provided a set of e-bike riding comfort variables, such as infrastructure facilities and e-bike performance in both pre- and peri-pandemic situations. This study also documented the potential effect of e-bike substitution for other transport modes such as public transport and cars. From a tactical level of analysis, there was a lack of studies to facilitate understanding the riding characteristics associated with e-bikes, specifically where vulnerable road users are involved. To address this knowledge gap, the interaction between e-bike users and pedestrians was studied in an off-road facility experiment. The study was designed to evaluate whether the traffic characteristics of passing (same-direction) and meeting (opposite-direction) encounters impose different difficulties for the navigation of the e-bike rider in pedestrian crowds. The results suggested that passing events cause the e-bike rider more hindrance compared to meeting events. This study was further extended to investigate the sociodemographic characteristics of e-bike riders along with their characteristics of riding in traffic and eventually model e-bike riders’ comfort in pedestrian crowds. In sum, this thesis addresses the knowledge gaps related to e-bike comfort concerns based on different study setups, which can be used substantially for developing ELOS. Along with exploring e-bike riders’ comfort concerns, the thesis puts forward information related to e-bike nonusers in both pre- and peri-pandemic situations. The findings of the thesis are applicable for planners and policy-makers when integrating the role of e-bikes in mobility policies. At a general level, the findings of the studies presented in this thesis pave the way for developing future ELOS and highlight the dire need to develop the concept of ELOS based on different contexts. All in all, the thesis opens new avenues into the field of e-bike comfort modelling by rendering the importance of the subject as an independent mode of transport

Investigating the Influence of Dockless Electric Bike-share on Travel Behavior, Attitudes, Health, and Equity

Cities throughout the world have implemented bike-share systems as a strategy for expanding mobility options. While these have attracted substantial ridership, little is known about their influence on travel behavior more broadly. The aim of this study was to examine how shared electric bikes (e-bikes) and e-scooters influence individual travel attitudes and behavior, and related outcomes of physical activity and transportation equity. The study involved a survey in the greater Sacramento area of 1959 households before (Spring 2016) and 988 after (Spring 2019) the Summer 2018 implementation of the e-bike and e-scooterservice operated by Jump, Inc., as well as a direct survey of 703 e-bike users (in Fall 2018 & Spring 2019). Among householdrespondents, 3–13% reported having used the service. Of e-bike share trips, 35% substituted for car travel, 30% substituted for walking, and 5% were used to connect to transit. Before- and after-household surveys indicated a slight decrease in self-reported (not objectively measured) median vehicle miles traveled and slight positive shifts in attitudes towards bicycling. Service implementation was associated with minimal changes in health in terms of physical activity and numbers of collisions. The percentages of users by self-reported student status, race, and income suggest a fairly equitable service distribution by these parameters, but each survey under-represents racial minorities and people with low incomes. Therefore, the study is inconclusive about how this service impacts those most in need. Furthermore, aggregated socio-demographics of areas where trips started or ended did not correlate with, and therefore are not reliable indicators of, the socio-demographics of e-bike-share users. Thus, targeted surveying of racial minorities and people with low-incomes is needed to understand bike-share equity

Crossing Reliability of Electric Bike Riders at Urban Intersections

This paper presents a crossing reliability model of electric bike riders at urban intersections using survival analysis approach. Riders’ crossing behavior was collected by video cameras. Waiting times in the red-light phase were modeled by reliability-based model that recognizes the covariate effects. Three parametric models by the exponential, Weibull, and log-logistic distributions were proposed to analyze when and why electric bike riders cross against the red light. The results indicate that movement information and situation factors have significant effects on riders’ crossing reliability. The findings of this paper provide an important demonstration of method and an empirical basis to assess crossing reliability of electric bike riders at the intersection
