  Reliable and an efficient Public Transport plays key role in establishing sustainable Urban Transport system and healthy environment in any city. Public Transport equity in terms of easy access for the commuters is very crucial. With the drastic increase in population and cities extent in developing countries like Pakistan, the travel demand is recklessly increasing which urge to provide efficient public transit which may cater the ever increasing transport demand. Lahore being the provincial capital of Punjab and the second most densely populated city of Pakistan, has a remarkably large transportation network. The case study presented an advanced approach to determine the population with walking access to transit stop of Lahore Public Transport network, by using Geographical Information System (GIS). This approach is quite efficient, reliable and helpful to investigate the effectiveness of transit network, user's access to transit stops and spatial gaps in the transit facilities. GIS-based network service area analysis has been utilized to find the transit stop service area of the existing public transport network in metropolitan city Lahore. To  find the transit stop service area, suitable walking time of 8 min or threshold distance of   624 m with walking speed of 78 m/min has been used as a standard. Transit stop service area has been used to find the population with walking access to a transit stop. The results reveal that only 40% of the total population was in suitable walking distance, which shows that less serviceability is due to the improper spatial distribution of existing transit stops across the transit route. The results also identify the population which is not in suitable walking distance to transit service. This study concludes that Geospatial Techniques are significant in assessment of the effectiveness and subsequently measuring the gaps in the existing transport network. Thus, on the basis of these results sustainable solution would be presented to enhance the efficacy of the integrated public transport.

Public transport coverage fails to keep pace with urbanization and urban expansion, which makes the “last kilometer" problem of residents’ travel increasingly prominent”. However, the practice has proved that microcirculation public transportation plays an important role in expanding the coverage of public transportation and promoting the integration of public transportation. Therefore, this paper takes a city bus community as an example. Firstly, it analyses the bus travel demand of commuters connecting to the subway station during the early workday rush hours on basis of IC Big Data, obtains candidate stations of microcirculation bus lines through K-means clustering. Secondly, it establishes the model, the target of which is to minimize  the cost residents' travel and bus operation, under the limited condition of walking distance, passenger number, station spacing and departure frequency. Finally, the genetic algorithm is used to find the optimal solution of the model, so it’s no doubt that the most feasible circular bus route is obtained. The results have positive significance for promoting the construction and operation of public transport integration and promoting the convenience and efficiency of public transport travel.

Transport sector is one of the main sources of anthropogenic greenhouse gases (GHG) emissions. Comprehensive countermeasures are needed in cities to mitigate transport GHG emissions. After reviewing green traffic measures that implemented by Shanghai since bidding for Expo 2010, this paper analyzes the achievement that Shanghai has made in carbon mitigation. The results showed that travel demand management and the constrcution public transportation infrastructure promoted by the event played a vital role in promoting mode shift to form public transport oriented traffic system. Carbon emission intensity of Shanghais urban transport declined steadily from 1.66 kg/trip to 1.55 kg/trip. The CO2 reduction attributable to mode shifts amounted to 4.99 million tons. It demonstrated that Shanghai Expo has promoted the city in carbon emission reduction through public transport improvement, new energy vehicles innovation, car growth restriction measures and green commuting initiate.

In this study, we addresse traffic congestion on river-crossing channels in a megacity which is divided into several subareas by trunk rivers. With the development of urbanization, cross-river travel demand is continuously increasing. To deal with the increasing challenge, the urban transport authority may build more river-crossing channels and provide more high-volume public transport services to alleviate traffic congestion. However, it is widely accepted that even though these strategies can mitigate traffic congestion to a certain level, they are not essential approaches to address traffic congestion. In this study, we consider a channel toll scheme for addressing this issue. Additional fares are applied to private vehicles, that an appropriate number of private vehicle drivers are motivated to take public transport or switch to neighboring uncongested river-crossing channels. To minimize the toll surcharge on both neighboring channels, while alleviating the traffic flow to a certain level, in this study, we provide a bi-objective mathematical model. Some properties of this model are discussed, including the existence and uniqueness of the Pareto optimal solution. To address this problem, a trial-and-error method is applied. Numerical experiments are provided to validate the proposed solution method.

Public Transport System

The public transport system is considered as one of the most important subsystems in metropolises for achieving sustainability objectives by mediating resources and travel demand. Representing the various urban transport networks is crucial in understanding travel behavior and the function of the transport system. However, previous studies have ignored the coupling relationships between multi-mode transport networks and travel flows. To address this problem, we constructed a multilayer network to illustrate two modes of transport (bus and metro) by assigning weights of travel flow and efficiency. We explored the scaling of the public transport system to validate the multilayer network and offered new visions for transportation improvements by considering population. The proposed methodology was demonstrated by using public transport datasets of Shanghai, China. For both the bus network and multilayer network, the scaling of node degree versus Population were explored at 1 km * 1 km urban cells. The results suggested that in the multilayer network, the scaling relations between node degree and population can provide valuable insights into quantifying the integration between the public transport system and urban land use, which will benefit sustainable improvements to cities.

Transport Modes

A sustainable transportation system requires a larger contribution to public transport share in comparison to private transport. Bangkok Metropolitan, the study area, exhibits a significant transport modal alteration trend towards public transport, in line with the expansion of Bangkok Transit System (BTS) and Mass Rapid Transit (MRT) for more coverage within the metropolis along main roads along with expansion of public bus routes, which increases the seamlessness and reduces transit time. This study is important as we believe that the higher seamlessness the more urban travelers would shift to using public transport modes. This matter is considered as a pertinent urban transport problem. This study aims at understanding the level of transit seamlessness of the Bangkok public transport system.  The study was carried out by firstly measuring six factors of the regular transit process, on formal and informal transport modes used by Bangkokians. These six factors were observed along the origin and the destination of the travelers with respect to travel time, number of transit points, average transit time, comfort, and transit facilities including facilities for disables, and walking distance. A total number of 300 public transport users were selected as respondents, 50 respondents for each selected transit hub. The selection was based on convenient random sampling considering the variability of destinations and purpose of travel. Despite a different destination, the residence was set as the origin. By using Modified Quantitative Gap Analysis, based on six selected transit hubs, the study found that the seamlessness of the inter-modal transits in Bangkok exhibits a characteristics of hard transit process, particularly for disabled people, notwithstanding the continuous efforts to make the seamless transit are in place, particularly with respect to infrastructure facilities.

Baghdad city depended on the private auto in transport and this led to great problems with increasing congestion and traffic problems. Existing public transport suffers from poor accessibility to opportunities which is considered the main existing problem. The local agency decided to construct Baghdad Elevated Train as one of the keys to solve this problem and decrease congestion. This study aims to discuss the changes that the installing of the planned train line could make, by using the Geographical Information System (GIS) to model the transportation networks (sidewalks, public transport network, and the planned elevated train) for two scenarios, first for the current public transport network and second for the long-term situation of the adding of the planned train, furthermore, to find the coverage area for each station and determine the population can be served for each station depending on the census of the zones for the year 2020. The modeled network databases were used to create the closest facility between the centroid of the 43 zones and the selected facilities (Commercial, Educational, Governmental, and Hospitals). The results revealed that the additional service of the train reduced the travel time between Al-Sadr City to four destinations selected for the mentioned facilities by the following percentages (62%, 40%, 46%, and 65%) respectively. Moreover, the population coverage stated that stations 8, 9, and 10 are the most populated.

Sebagaimana kota–kota metropolitan di dunia, kemacetan menjadi permasalahan utama dalam bidang transportasi perkotaan. Kemacetan terjadi pada umumnya karena ketidakseimbangan antara penyediaan (supply) dengan permintaan (demand). Usaha untuk menekan jumlah kendaraan di jalan, salah satunya, adalah dengan mempromosikan pengunaan angkutan umum kota. Oleh karena itu diperlukan sebuah perencanaan penyediaan fasilitas angkutan umum. Untuk memperkirakan permintaan angkutan umum dibangun model lalu lintas yang mereplikakan bangkitan, pola dan pembebanan perjalanan. Hasil kalibrasi model distribusi perjalanan menggunakan gravity model diperoleh fungsi impedance yang terbentuk dari fungsi waktu perjalanan dengan faktor  sebesar 0.063. Perbedaan mean trip length model (dengan observed adalah -5,4%. Mean trip length (MTL) model dengan angkutan umum adalah 17,04 menit dan hasil survai 18,02 menit. Model yang terbangun validasinya cukup baik dengan indikator R2 terhadap data observed sebesar 0,88. Hasil dari seluruh tahapan proses pemodelan diperoleh total permintaan perjalanan dengan angkutan umum tahun 2030 diperkirakan mencapai 67.800.434 penumpang/tahun.Kata kunci: Angkutan umum masal, Distribusi perjalanan, Gravity model.AbstractAs metropolitan cities in the world, congestion becomes a major problem in the field of urban transport. Congestion occurs generally due to an imbalance between supplyand demand. Attempts to reduce the number of vehicles on the road, one of which, is to promote the utilization of public transport. Therefore we need a plan for the provision of public transport facilities. To estimate the demand for public transport, it is built transport model which is replicating the trip generation, trip distribution and trip assignment. The results of the trip distribution model calibration using a gravity model obtained impedance function which is formed from travel time functionby a factor of 0.063. Mean trip length difference between model and observed is equal -5,4%.Mean trip length (MTL) model utilizing public transportsis about 17.04 minutes whereasMTL resulted from traffic survey is about 18.02 minutes.The model validation is quite well with observed data by showing the R2 indicatorof about 0.88.The results fromall stages modeling process obtained total travel demand by public transport in the year of 2030 is estimated at about 67,800,434 passengers/year.Keywords: Mass transit, Trip distribution, Gravity model.

The article analyzes congestion of the urban transport network in Kyiv and its impact on air pollution in the city and suggests ways to solve problems that occur because of it. The object of the study is public transport, specifically electric buses. The purpose of the work is to propose an innovative approach to the use of electric buses using analysis of air pollution indicators, the traffic index of urban congestion and the non-stationarity of the passenger flow. Research methods are generally scientific. The city of Kyiv ranks number 7 in the world in terms of traffic congestion and the amount of added time that people spend due to congestion. The transport network overload leads not only to congestion, but also to air pollution in the city. The authors of the article analyze the air pollution and the state of congestion on the roads of Kyiv. In order to improve the current situation in the city, the concept of modular use of electric buses is proposed, which envisions production of electric trucks and electric trailers for passenger transportation (modules) to it. The use of electric buses reduces environmental pollution, but does not solve the problem of congestion in megapolises. The solution to the problem must use comprehensive approach. The authors came to conclusion that it is not possible to significantly influence the non-stationary flow of passengers, but it is possible to release a fleet with different passenger capacity at different times of the day. During rush hours the proposal is to limit the total number of cars and release an electric bus with the module of the largest capacity, in the late evening and at night release fleet with modules designed for a small number of passengers, in other hours release electric buses with a medium capacity module. The modular principle of formation of electric bus routes will optimize the general expenses for transportation and will take into consideration seasonal, weekly and daily non-stationary flow of passengers. Development of this modular electric vehicles will be the task for automotive industry.
