For bus service quality and line capacity, one critical influencing factor is bus stop capacity. This paper proposes a bus capacity estimation method incorporating diffusion approximation and queuing theory for individual bus stops. A concurrent queuing system between public transportation vehicles and passengers can be used to describe the scenario of a bus stop. For most of the queuing systems, the explicit distributions of basic characteristics (e.g., waiting time, queue length, and busy period) are difficult to obtain. Therefore, the diffusion approximation method was introduced to deal with this theoretical gap in this study. In this method, a continuous diffusion process was applied to estimate the discrete queuing process. The proposed model was validated using relevant data from seven bus stops. As a comparison, two common methods— Highway Capacity Manual (HCM) formula and M/M/S queuing model (i.e., Poisson arrivals, exponential distribution for bus service time, and S number of berths)—were used to estimate the capacity of the bus stop. The mean absolute percentage error (MAPE) of the diffusion approximation method is 7.12%, while the MAPEs of the HCM method and M/M/S queuing model are 16.53% and 10.23%, respectively. Therefore, the proposed model is more accurate and reliable than the others. In addition, the influences of traffic intensity, bus arrival rate, coefficient of variation of bus arrival headway, service time, coefficient of variation of service time, and the number of bus berths on the capacity of bus stops are explored by sensitivity analyses.

In the current system, school bus stops in Howard County, Maryland are manually placed along the school bus routes based on safety, cost-efficiency, and many other variables. With such liberal placement, bus stops are sometimes placed unnecessarily. This issue is prevalent in many school districts and often results in needlessly close bus stop proximity. In this study, the authors implemented a GIS-based heuristic to assist school officials in optimizing their districts bus stop placement. They also estimated the proportion of county-wide bus stops that could be eliminated by this approach. Following the constraints determined by State and local guidelines, the ArcGIS Network Analyst Extension was used to identify unnecessary bus stops across the study area. The initial output was re-evaluated by school officials in order to determine if those bus stops would be eliminated. The results indicate that approximately 30% of the existing bus stops were marked as “candidates for elimination” by the GIS process. After a review of these candidates, it was determined that at least 15% of the total school bus stops could be eliminated. Statistical estimates lent credence to the benefit of a re-evaluation of these bus stops. The method developed in this study can easily be replicated. Hence, it may inspire other school systems to exercise the same approach. Additionally, the results provide a gateway for future studies in examining more efficient school bus routes with less travel time, as well as investigating how much the carbon footprint of school bus fleets can be reduced.

Aiming at the problems of poor time performance and accuracy in bus stops network optimization, this paper proposes an algorithm based on complex network and graph theory and Beidou Vehicle Location to measure the importance of bus stops. This method narrows the scope of points and edges to be optimized and is applied to the Jinan bus stop network. In this method, the bus driving efficiency, which can objectively reflect actual road conditions, is taken as the weight of the connecting edges in the network, and the network is optimized through the network efficiency. The experimental results show that, compared with the original network, the optimized network time performance is good and the optimized network bus driving efficiency is improved.

We study how N intelligent buses serving a loop of M bus stops learn a no-boarding strategy and a holding strategy by reinforcement learning. The no-boarding and holding strategies emerge from the actions of stay or leave when a bus is at a bus stop and everyone who wishes to alight has done so. A reward that encourages the buses to strive towards a staggered phase difference amongst them whilst picking up passengers allows the reinforcement learning process to converge to an optimal Q-table within a reasonable amount of simulation time. It is remarkable that this emergent behaviour of intelligent buses turns out to minimise the average waiting time of commuters, in various setups where buses move with the same speed or different speeds, during busy as well as lull periods. Cooperative actions are also observed, e.g., the buses learn to unbunch.

Bus Stops

Walking and transit are the backbone of sustainable mobility. Bus stops not only represent the connection between the two, but are also central in dictating the attractiveness of the latter. Accessibility of bus stops becomes, then, pivotal in increasing both attractiveness and sustainability of public transport. The paper describes a multi-step methodology to evaluate bus stops’ accessibility starting from a cluster of seven indicators describing objective and subjective features influencing passengers’ choice toward a given bus stop. The indicators are weighed by a questionnaire submitted to experts. Finally, a multicriteria analysis is developed to obtain a final score describing univocally the accessibility of each stop. Outcomes are mapped and a case study in Rome is reported as an example, with 231 bus and tram stops assessed accordingly. Results shows the relevance of the urban network and environment in evaluating the accessibility and in promoting more sustainable mobility patterns. Research innovation relies on the possibility to merge data from different fields into a specific GIS map and easily highlight for each bus stop the relationships between built environment, passengers’ comfort, and accessibility, with the concluding goal to provide advanced knowledge for further applications.

Purpose of Study: The purpose of this study is to investigate the efficiency of bus bay compare to the curbside bus stop in a midblock road segment of Dhaka city. Methodology: Vehicle composition and traffic volume were counted on-peak hours for the midblock of Azimpur road near the existing bus stop. Simulation models were developed in VISSIM, where Model 1 represented the existing road scenario with curbside bus stop, and Model 2 represented the same road segment with a bus bay. Main findings: The simulation result showed that Model 2 outperformed Model 1 due to the presence of bus bay. Comparing Model 1, travel time and delay reduced by varying 1.80% to 12.5% and 6.25% to 100% respectively in Model 2 during the simulation. Similarly, average speed increased by 1.39% and density decreased by 61.29% in model 2. Application of this study: Curbside bus stops result in abrupt halt, disrupt traffic flow, and queuing of the small-sized vehicle behind buses. These bus stops caused traffic congestion and delays in urban roads which can be alleviated by alternatives, such as, bus bay. The novelty of this study: The bus bay is a good alternative to the curbside bus stop, which can improve existing traffic conditions in urban roads.

Traffic Behavior

In this paper, a two-lane traffic system consisting of a mixture of buses and cars is studied. The buses stop at each bus stop to pick up passengers and are not allowed to change lane. The cars may change lane when hindered by preceding vehicles. Our simulations show that with a fixed number of buses, four states of the traffic system are identified. The spatial-temporal plots of the four traffic states, and the trajectories of buses at different densities are presented. A gradual transition instead of sharp phase transition from bunching state to homogeneous state of the buses is found. Next, we study the system behavior at different number of bus stops, and an optimal number of stops is suggested. Finally, the influence of bus stops on the fundamental diagram is studied.

Four large, and often overflowing, dumpsters are situated at one of the more than dozen bus stops at the Chicago Transit Authority's (CTA) Red Line 95th Street/Dan Ryan train station. This station is on the city's far south side and the ridership on the buses that board and disembark there and the train is predominantly minority. On a warm or hot day, the smell of bus engines and dumpster contents fill the waiting areas. One 28–year–old Black male passenger (BMP) noted, as he stood at one of the nearly one dozen (no seating available) bus stops at the station, “In the summer it's really horrible because of the smells, flies, and bees.” He also added that as far as he could remember “they've [the bus stop dumpsters] been here my whole life” (June 2012). His experience at the south end of this train line, which also has a majority minority ridership, is starkly different from the waiting experiences on the far north end of the same line, Howard Street, where the ridership is diverse (with a large white ridership). The north end station is surrounded by shops and restaurants, more open waiting spaces, and places to sit to wait for buses that travel through the adjoining bus depot. There are no bus stop benches at the south end station, even though there are over a dozen buses that use that station's depot.

Standard Concept

Rural transportation system is far behind when compared with urban transportation which resulted in decrease of rural transport demand. Therefore, for increasing the rural transport demand is needed a standards and concepts of rural transport for improving transport services both in infrastructure and facilities. Bus stop for rural transport is One of the support facilities that no avilable. This standar involves a specific standard for rural transport. The study was conducted in Jember and District Kalianda. The method used in this study is a qualitative and quantitative analysis. Analyses were performed using standard guidelines stop I stops of public transport which will be further developed a standard stop for rural transport. The analysis is based on the major facilities and supporting public transport standards issued by the Directorate General of Land Transportation can not be met properly. In other hands, planning of bus stop is appropriate but layout of bus stops at the intersection is outside the specified minimum standards. To obtain the size of the standard concept of bus stop (length: 3m-5meter ), location of bus stops that have noticed the condition of the land use and supporting facilities of bus stop such as pedestrian markings should be provided.Keywords: rural, bus stop, rural transport Sistem transportasi perdesaan memang jauh ketinggalan jika dibanding dengan transportasi perkotaan yang berakibat pada kurang diminatinya angkutan perdesaan. Untuk itu diperlukan suatu standar-standar dan konsep peningkatan pelayanan angkutan perdesan baik dari sisi prasarana dan sarana maupun dari kompenen utama dan komponen penunjang. Salah satu fasilitas pendukung yang belum ada standarnya adalah halte dan tempat hentian untuk angkutan perdesaan. Untuk itu diperlukan suatu standar khusus untuk angkutan perdesaan. Penelitian dilakukan di Kabupaten ]ember dan Kabupaten Kalianda. Berdasarkan hasil analisis diperoleh bahwa fasilitas utama dan penunjang sesuai standar angkutan umum yang dikeluarkan oleh Ditjen Perhubungan Darat tidak dapat terpenuhi dengan baik sedangkan dari sisi perencanaan sudah sesuai kecuali letak halte dengan persimpangan masih diluar standar minimum yang telah ditentukan. Untuk konsep standar halte diperoleh ukuran halte (panjang 5 meter-3meter), lokasi halte yang telah memperhatikan kondisi tata guna lahan dan fasilitas pendukung halte seperti marka penyeberang jalan harus disediakan.Kata Kunci : perdesaan, halte, angkutan perdesaan
