The effectiveness of special carriages for female in protecting female train passengers

PT Kereta Commuter Indonesia (KCI) is one of PT Kereta Api (KA) Indonesia managing Greater Jakarta Commuter Trains. PT KCI started to provide special carriages for females during peak hours in 2011. Up to December 2019, PT KCI has 1,100 units of electrical carriages. In 2019, the average daily passengers were 979.853 on weekdays with maximum daily passengers of 1,154,080. PT MRT Jakarta started to provide special carriages for females during peak hours in May 2019, about 2 months after its opening of phase 1a from Lebak Bulus to Bundaran HI. By operating 16 transit units the average daily passengers are 83,000 with maximum daily passengers 93,000. The availability of special carriages for females was intended to protect female passengers from criminal acts and sexual harassment. However according to previous research an media coverage, the special carriages were not consistently provide a positive impact to female passengers. This research is intended to evaluate this issue and provide recommendations regarding this service.

Management of Urban and Regional Rail: Case Study Bucharest

Abstract The capital of Romania is the main railway hub of the country. As such, the railway network around the capital is quite extensive, with main cities around it being directly connected by rail. Despite this, there are no regular train services for commuters, similar to other large European cities. This paper aims to analyze the current state of railway passenger transport in the region surrounding Bucharest, to highlight the weaknesses of the network and to present a guideline for the implementation of an efficient commuter service. 100 stations in and around the city were evaluated with regard to their degree of accessibility (DoA), defined as the location of the station relative to the nearest settlement. Train frequency, travel times and journey costs were determined for each line originating in Bucharest. These variables were compared to their road equivalents to highlight the differences between these two modes of transport. Low train frequency and the remoteness of many stations were determined to be the main obstacles in establishing an appropriate commuter service. Reworking future timetables to prioritize commuter trains is proposed as a short-term solution, while line improvements and better integration with existing public transport are set as priorities.

Take the Eh? train: Distributed Acoustic Sensing (DAS) of commuter trains in a Canadian City

We attach a Distributed Acoustic Sensing (DAS) system to an existing telecom fibre that follows the Red Line of the City of Calgary Light Rail Transit (LRT). The City does not have a Global Positioning Satellite (GPS) system to track the position of trains on the Red Line, and very few trains in the fleet are even GPS equipped. Therefore, we propose DAS tracking as an alternative to the retrofit and development of a GPS-based system or as a companion to a future system. Trains on the Red Line register as intensity peaks in the DAS soundfield, and we deduce the DAS distance between the City Hall LRT station (the origin) and the Tuscany station (the terminus) for all trains on the system by tracking intensity peaks.To estimate DAS position from DAS distance, we use the speedometer logs and GPS-position logs from one of the few GPS-equipped trains on the Red Line. We track this train with DAS during three trips from City Hall station to Tuscany station and then obtain the logs for those trips. Analysis of the logs shows that more than 98% of the GPS positions are either null-valued or are repeats of previous values. This paucity of actual positions suggests that the effective GPS positions lie on a very coarse grid. We convert the coarse GPS-positions into GPS distances and interpolate them onto the dense speedometer-grid using a Kalman filter. The heading along the Redline changes more slowly than its distance so we approximate a unit heading-vector on the dense grid. We show that the product of the Kalman GPS-distance and the unit heading-vector gives an optimal GPS heading-vector on the dense grid. Latitude and longitude at points along the dense grid correspond to the north-south and east-west components of the GPS heading-vector, respectively.We Kalman filter the DAS distances onto the dense-grid and we find also that this minimizes a number of DAS noise sources. With the Kalman DAS-distances and Kalman GPS-positions on the same dense-grid, we now have an optimal relationship that is time independent. For as long as the fibre and the Red Line themselves remain stationary, all DAS distances obtained from tracking future trains defines unique latitude and longitude positions in realtime.

Impact of the Chicago soundscape on building envelope design

Chicago's unique soundscape, dominated by buses and other street traffic, commuter trains, and the City's signature “L,” both driven and augmented by the dense development in the urban core and preponderance of high-rise buildings, places demands on building envelope design. Building envelope design must address noise isolation at the fac¸ade of the structure and the frequent use of extensive glazing means that noise isolation has particularly large cost implications. Through measurements and acoustic modeling, the sound level can be quantified and predicted over the fac¸ade of a building under design. The results advise the envelope assemblies and acoustical design goals. This presentation will provide examples of the sound levels measured at various locations around the City, illustrate acoustic modeling that has been used to predict noise levels over the building fac¸ades under design, and describe envelope assemblies and acoustical design criteria that have been used.

Development of the system of rationing and accounting for performance indicators of long distance and commuter train schedules for railways and the network as a whole

Currently, rationing and accounting of performance indicators for long distance and commuter train timetables for railways is carried out on the basis of the principle of achieved level. Methodology for calculating indicators based on objective conditions for organizing operational work on each railway has been developed. The generalized indicator characterizing the objective conditions is determined by the authors on the basis of an analysis of a set of factors, which include: loading of the railway infrastructure by train traffic; technical and technological state of infrastructure and rolling stock; risks associated with a possible delay of trains during the period of providing windows for the repair and reconstruction of infrastructure devices; number of passenger train stops; climatic conditions; technological discipline for fulfilling the traffic schedule (it is assumed to be the same for all railways); risks of violation of timetables on lines with dense train traffic. Dependencies for determining the numerical values of the factors are proposed. Taking into account the weight coefficients of each factor, the estimated indices of the objective conditions of the operation of each railway for long distance and commuter traffic are determined. The network task by the level of execution of schedules is distributed by railways in proportion to the values of their estimated indices. The transition to the proposed system of rationing and accounting for the performance of timetables will help to improve the quality of performance of the train schedule, to ensure a positive image of the Russian Railways in the field of passenger transportation. The use of the proposed methodology for determining the target indicators of the schedules of long distance and commuter trains ensures that the real conditions of the transportation process on each railway are taken into account at the planning stage and allows an objective assessment of the quality of the organization of operational work based on the results of the fulfillment of planned targets.

Additionally, the BS, α(G), NBS, and αk(G) concepts were presented in IFGs. Three different examples were described to show the informative development procedure by applying the idea to IFGs. Considering the examples, some results were developed. Also, the applications were utilized in water supply systems. The present study was conducted to make daily life more useful and productive.

INTEGRASI HUNIAN DALAM TOD UNTUK MENGATASI PERMASALAHAN TRANSIT KAWASAN PASAR LAMA, TANGERANG

&#x0D; &#x0D; &#x0D; Title: Residential Integration in TOD to Overcome the Transit Problem in Pasar Lama Area, Tangerang&#x0D; The Pasar Lama (Old Town Market) area is known as a highly developing area in the city of Tangerang. This area facilitated with a commuter train station used by people commuted from Tangerang to Jakarta in daily basis – both for transitting and shopping purposes. Tangerang Station is the main train station for commuters’ from-and-to Jakarta; therefore, urban issues arise in the main urban nodes of the area, specifically the main boulevard near the station and the market. Issues such as transportation traffic, pedestrian congestion, informal street-vendors activities, and the arrangement of residential areas are major concern that needs to be addressed in the purpose of creating a good urban public space in the region. The solution to overcome this problem is to apply a concept for a TOD (Transit Oriented Development). TOD is a sustainable transportation system approach that provides accessibility and alternative modes of transportation. With the implementation of TOD in the transit station area, it is expected that the entire Pasar Lama area will be developed and created a good urban public space. This research study aims to answer several research questions, for instance: how does the concept of the TOD is able to integrate a residential program into the development and create a successful an urban public space as a transit area in the area of Pasar Lama, Tangerang. This research begins with context analysis based on several theories about urban dimension, human scale and key factors of a TOD. Precedent studies and observations on surrounding site, serve as references in analyzing and proposing draft concepts for this particular neighborhood. This research study will have an outcome in the form of design concept proposal that allow TOD to incorporate residential, parking, commercial, and open space as one district to revitalize the congested neighborhood in the Pasar Lama area, Tangerang.&#x0D; &#x0D; &#x0D;

Noise exposures in different community settings measured by traditional dosimeter and smartphone app

While occupational noise exposures are well understood in certain industries, increasing attention has recently been given to exposures in non-traditional and non-occupational settings. Further, there is growing interest in the use of smartphone sound level meter applications (apps) as an alternative to traditional noise measurement devices such as personal dosimeters. This research utilized a smartphone running the National Institute for Occupational Safety and Health (NIOSH) sound level meter app and a noise dosimeter to measure noise exposures in office, coffee shop, commuter train, restaurant, and spin class settings. Overall (N = 166), noise levels ranged from between 47.7 dBA and 42.6 dBA in the office setting to 101.2 dBA and 101.7 dBA in the spin class, for the smartphone and dosimeter, respectively. The mean difference in measurements was found to be less than 2.0 dBA (within the accuracy of typical noise measurement instruments) for measurements made in a commuter train, restaurant, and spin class locations. Our results suggest that the NIOSH app (without calibration or an external microphone) can be used as an effective screening tool in some settings, particularly when noise levels are stable and exceed 75 dBA. These results are especially timely as wearables (watches and fitness bands) begin to use internal microphones to measure sounds levels. These technologies may face similar measurement issues as we have identified for smartphones without an external calibrated microphone.

Potential for metro rail energy savings and emissions reduction via eco-driving

Metro rail energy efficiency needs to be improved to compensate for growing capacity demand. Eco-driving aims to reduce energy consumption without affecting safety and passenger comfort. Estimates of energy savings from train eco-driving are typically based on theoretical speed trajectory optimization models. However, achievable energy savings from eco-driving should be assessed based on realistic trajectories. A Markov chain speed trajectory simulator calibrated to measured trajectories was used to simulate realistic inter-run variability in 1 Hz trajectories. The simulator was calibrated and applied to the Washington Metropolitan Area Transit Authority Metrorail system. Estimated energy consumption for each trajectory includes auxiliary loads and tractive effort to overcome resistive forces. Inter-run variability in estimated energy consumption implies opportunities for energy savings via eco-driving. Energy savings was quantified by comparing the lowest and average segment energy consumption. A segment is the one-way rail track between adjacent stations of each line. Simulated trajectories are similar to measured trajectories based on mean absolute error and coefficient of determination (R2) for the same operation mode sequence. Based on 100 simulations per segment, energy savings ranging from 5% to 50% among segments and from 14% to 18% at the system level can be achieved without modifying travel time. Energy savings lead to reduced electricity consumption and, therefore, reduced power generation emissions. The method demonstrated here to quantify opportunities for metro train energy conservation and emissions mitigation is broadly applicable to electric metro and commuter trains and rail segments. Implications for energy-efficient passenger rail planning and operation are discussed.

Investigation of prestressed concrete sleeper’s vibration located at KM71.75 And KM79

Train has been one of the essential and convenient transportation choices for community nowadays. Instead of carrying a passenger, these types of facilities also can be used to transport material across our country. With the increasing usage of train every year, the rate of accidents has also increased dramatically. Therefore, the importance of studying about the railway can contribute to building better and comfort railway track which can deliver their services at its best for an extended period. This study focused on the measurement of the deflection of concrete sleepers which affect the performance of the railway track. Lack of actual deflection value from the site can be problematic to ensure the quality of the track itself. The method used for the analysis is by using the Sirius-M instrument which can be recorded and analyses the acceleration of the concrete sleepers when receiving the loading wave from a moving train. The data of acceleration then can be transformed into deflection form by applying double integration. From the data collection, it shows that the maximum deflection at northbound at KM79 is 13.72 mm for freight train and 1.5 mm at southbound for six set commuter train. As for KM 71.75, the maximum deflection at northbound is 0.57mm for ETS and 1.5mm at southbound for six set commuter train. Thus, from this research, the actual deflection value from both sites were achieved.

Explaining dwell time delays with passenger counts for some commuter trains in Stockholm and Tokyo

In both Stockholm and Tokyo, small dwell time delays of at most 5 min make up around 90% of the total delays for commuter trains. To understand these disturbances, we use high resolution data on dwell times and passenger counts from both countries over the last several years. We find that trains in Tokyo are much more congested than in Stockholm, and that the exchange of passengers is modest at most stations in the latter city. In both cities, the range of dwell time delays is quite narrow, with between 40 and 50 s separating the 5th and 95th percentiles. Most delays are thus very small, and even small adjustments to dwell times can make a big difference overall. We find that the data on passengers explain about 40% of this variation in dwell time delays, if we account for non-linear and interaction effects, which is thus a ballpark estimate for how much the exchange of passenger contributes to delays for these trains. We also produce simple, linear models which can be used in practice to assign more appropriate dwell times. To facilitate such improvements, key stakeholders and practitioners have been closely involved with the research in both countries.

Single and Multi-Mode Choice Commuting Models in Surabaya and Sidoarjo Region

Large urban areas require a reliable multi-modal transport system to serve the needs of urban commuters. Urban public transport is currently still considered minimal by users of Multi mode (public transport). This has an impact on the dominance of single private modes, especially Single mode (motorcycles) that impact on city congestion, a mode that today can still be relied upon by urban commuters, to meet expectations in terms of quality of service, cost, time, experience and accessible only commuter trains. It takes effort to divert the end-user of the motorcycle to the final destination to switch to motorcycle over commuter train to get to the final destination. The study focuses on improving the comprehension of influencing factors, opportunities and models on the choice of single mode modes of multi mode switching, using the Binary Logistic Regression method with Stated Preference survey. The results Single mode user community in Surabaya and Sidoarjo willing to use the multi mode in case of improvement of service quality, affordable travel costs, travel time is adequate, and acces is enjoyable.

Metropolitan rail network robustness

In large-scale urban agglomerations, heavy rail in the form of metro and commuter train serves as the backbone of the metropolitan public transport network. The objective of this paper is to investigate whether networks with strikingly different structure and development pattern exhibit different robustness properties in the event of random and targeted attacks. We adopt a complex network theory approach, investigating network performances under alternative sequential disruption scenarios corresponding to the successive closure of either stations or track segments. We also investigate the case where the removal of a network node or link implies the closure of all traversing lines Network performance is measured both in terms of the capacity of the network to function in terms of connectivity as well as the additional impedance induced for those that remain connected. An aggregate robustness indicator based on the integral of the deterioration of network performance is adopted. Three exemplary networks are selected, the urban rail networks of London, Shanghai and Randstad. These three networks offer showcases of short and long development patterns, mono- and polycentric agglomeration structures, including the largest and the oldest metropolitan heavy rail networks. The polycentric network of the Randstad was found the least robust in this analysis when compared to the more monocentric networks of London and Shanghai. The London network is in general more robust than the Shanghai network thanks to the presence of cycles beyond the core. Our findings provide more nuanced evidence on the relation between network structure and development pattern, and its robustness.

Resilience and Vulnerability of Public Transportation Fare Systems: The Case of the City of Rio De Janeiro, Brazil

Resilience is the ability of a system to adapt, persist, and transform as a reaction to threats, which may be external or internal to the system, while vulnerability is the state of being susceptible to harm from exposure to stresses associated with environmental and social change and from the inability to adapt. Based on a study of the threats that can affect urban mobility, we identified a gap regarding the analysis of the levels of resilience and vulnerability in the face of subsidy threats that can severely affect developing countries. This article measures the level of resilience and vulnerability due to the absence of public transport fare subsidies. For this purpose, we developed an approach based on fuzzy logic and applied it in 33 administrative regions (ARs) of the city of Rio de Janeiro, Brazil. We obtained four matrices of the levels of vulnerability and resilience of each of the regions as an origin and destination. The results show that areas nearest to the downtown region and those with high-capacity transportation available (commuter train and/or subway, systems with many transfer points) are more resilient, while a high level of vulnerability is associated with low income, negative socioeconomic indicators, and the predominance of road transportation to reach jobs. The contribution of this paper is the method applied to analyse the levels of vulnerability and resilience of public transport, which includes a threat that can cause a rupture that impacts routines and job accessibility in a region.

Fuzzy Logic based Anti-Slip Control of Commuter Train with FPGA Implementation

In the railway industry, slip control has always been essential due to the low friction and low adhesion between the wheels and the rail and has been an issue for the design, activity, and operation of railroad vehicles. Slip is an unpredictable parameter in the railroad that disintegrates the surface of the railroad with a contact surface of the boggy wheel brought about by the mechanical force of traction phenomena, it destabilizes the railway traction which does not fulfill safety and punctuality requirements. In this paper, we present the work based on developing a fuzzy logic-based anti-slip controller for the commuter train using FPGA implementation which minimizes slip parameters. The development of a fuzzy logic-based anti-slip controller for the commuter train is designed in MATLAB and then tested for area-performance parameters in FPGA through the system generator library. Simulation is performed to demonstrate the effectiveness of the proposed fuzzy logic control system for anti-slip control under various parameters, the results of simulation prove the effectiveness of the proposed control system as compared with conventional PID controller and shows high anti-slip control performance under nonlinearity of brake dynamics.
