Overall Evaluation

Based on a questionnaire survey responded by nearly 11000 people in Beijing, from a perspective of livable city, the general characteristics and the spatial autocorrelation of the public transportation satisfaction were analyzed. The overall evaluation of public transportation satisfaction in Beijing is 67.31, indicating that more great efforts should be paid to improve the public transportation satisfaction level in construction of the livable Beijing. The spatial structure of Livable City Public Transportation Satisfaction shows a “hot banding” distribution pattern, accompanying with 3 “cool spots”. To get a better understanding of the spatial pattern of the public transportation satisfaction, we used the Moran’s I and LISA to measure the spatial autocorrelation. The results illustrate that the public evaluation on the public transportation is spatial dependent and has tendency toward clustering. The cluster of areas with High-High association is located in the south of Beijing near Chang’an Avenue, highlighting and reshaping like a hollow circle, while the cluster of areas with Low-Low association is located in northwest Beijing and outside of the 4th ring road. Overall, the LCPTS in the north of Beijing lags obviously behind the overall level. The phenomenon is mainly due to the long-term accumulation of urban development.

Do So

It is rare that municipalities have the opportunity to remake a significant portion of key infrastructure, and to do so without significant cost burden on the citizens. The advent of Uber and similar entities that have moved the ride-sharing concept into the 21st century provide that unique chance in the public transportation arena. However, cities such as Los Angeles, New York, and Chicago are responding to Uber as a threat to established taxi-livery services and their accompanying regulatory structures rather than an opportunity for modernization. in order to capitalize on this transformative moment, cities and governments must rethink and address decades-old rules, regulations, and entrenched interests. The benefits to and acceptance by the public that surround the ride-sharing movement are unprecedented. Whether today's politicians and regulators have the courage and foresight to embrace this fundamental change will determine the long-term success and the meaningful evolution of our national transportation newtork.

The City

With the aggravation of the traffic congestion in the city, car owners will have to give up commuting with private cars and take the public transportation instead. The paper uses the replication dynamic mechanism to simulate the learning and adjustment mechanism of the automobile owners commuting mode selection. The evolutionary stable strategy is used to describe the long-term evolution of competition game trend. Finally we simulate equilibrium and stability of an evolution of the game under a payoff imbalance situation. The research shows that a certain proportion of car owners will choose public transit under the pressure of public transport development and heavy traffic, and the proportion will be closely related to the initial conditions and urban transportation development policy.

Abstract After finishing the mining process, the best way to deal with the residual of open-cut coal mines in the north-western region of the Czech Republic has been proposed to be hydric recultivation. The area of our study is the first artificial Lake Most (formerly known as Ležáky-Most coal quarry) finished in 2014 and opened to the public in 2020 for recreational purposes. Since the lake is a closed system without natural inflow and outflow, the prediction of evaporation plays a crucial role in the securitization of long-term sustainability based on the capability of keeping the stable level of a dimension of the final water level. In this paper, we use the historical data consisting of the altitude of the lake level, its area, the perimeter of the shoreline, and especially the volume of refilled water. These data are compared against the computational methods; namely, the Penman-Monteith Equation and Hargreaves-Samani model calibrated by the method proposed in our previous work.

Marginal Cost Pricing

The article studies the development of the long-term marginal cost pricing of electricity in France, in the 1950s and 1960s. The engineers who managed the public monopoly for the production, transport, and distribution of electricity promoted a distinctive version of the economics and engineering nexus. Costs calculations were developed to design a nationwide integrated machine. Hydropower in the south was to be interconnected with thermal power in the north, in order to support a massive increase in consumption in the Paris basin, saving on coal and on the scarce funding of the Marshall Plan. Prices acted as administrative instructions, passing on costs to subscribers and shaping their present and future behavior according to the planned development of the system. This was a technocratic intervention: the engineer-economists made crucial and lasting decisions on land-use planning for the sake of the rapid growth of the system. This engineering and economics nexus was a far cry from the prewar liberal order made of multiple small and loosely regulated competitors, and from contemporary forms of economic engineering, more narrowly focused on the informational properties of prices, abandoning the calculated nationwide decisions on the growth of processes of production and uses. It is also slightly neglected in the discussion over the so-called indicative planning in postwar France.

ABSTRACT The recent drought events and the population growth in São Paulo State (Brazil) have caused many municipalities to increase the groundwater exploitation of the Guarani Aquifer System (GAS) for the public water supply. In Bauru City/SP, the extraction of water from this Aquifer is expected to increase from 3699 m3/h (2014) to 4465 m3/h (2034). However, its long-term overexploitation may compromise the amount of available groundwater. The Analytic Element Method was used for groundwater flow modeling at steady-state, which includes the regional flow, the water withdrawal from wells and the main local geological conditions. The hydraulic gradient 0.82 m/km was estimated in the GAS in Bauru City. The potentiometric drawdown in the GAS in Bauru was estimated as 50 m since the beginning of the groundwater exploitation. The drawdown for the groundwater pumping scenario in 2014 is higher than 15 m in Piratininga and Agudos and lower than 10 m in further cities. The expected drawdown for the scenario of 2034 can reach 15 m in comparison with the scenario of 2014, in the North of Bauru City, where the future wells will be located.

Transportation Service

Incheon is a major city comprising the metropolitan area around Seoul. However, it ranks the lowest in terms of road extension scale relative to population and number of vehicles. There is extreme traffic congestion and shortages of parking spaces in downtown Incheon, impacting traffic. Alternative policies of the municipal government to address these issues, including road extension and improving public transportation, have not shown results because of the low satisfaction level of the public transportation service and limited transportation mode transfer owing to travel within the metropolitan area. Therefore, to improve the public transportation service, conducting a comprehensive analysis on the current service and improving its quality were deemed necessary. Additionally, adopting a demand response public transportation service was considered. In conjunction, objective and easy-to-use data should be used, so that if anyone repeats the procedure, the same result should be obtained. For this, we propose the simplest process. Thus, to introduce the service, this study presents a decision-making process by establishing a regional prioritizing methodology based on the transportation environment satisfaction level, average access time to major facilities, public transportation competitiveness, personal vehicle demand, and existing public transit routes. To assess the methodology feasibility and conformity, user satisfaction was analyzed in Jung-gu, Incheon. The analysis showed 91% user satisfaction, verifying that the demand response public transportation service was effectively supplied. This analysis process will be useful when applying and expanding new transportation services.

For resolving or alleviating the transportation problems, it is necessary to efficiently manage the public transportation and provide public transport services with high quality and advocate green travel, which rely on accurate traffic data. In order to obtain more accurate bus speed in the future, this paper proposed a novel dynamic hierarchical spatial-temporal network model based on Grey Relation Analysis (EGRA), the convolutional neural network (CNN), and the gated recurrent unit (GRU). The proposed model is named the DHSTN; it exploited EGRA to analyze and choose the suitable candidate line sections with high impacts on the target section and, then, construct a multilayer structure based on the CNN, GRU, and attention mechanism to analyze and capture the spatial and temporal dependency, and finally, the extreme learning machine (ELM) is exploited for the fusion of the long-term and short-term dependency to predict the bus speed variation in the next time interval. Comparative experiments indicate that the DHSTN has better performances, the mean absolute error is around 2.6, and it meets the real requirements.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.
