Modelling induced travel demand in a developing country: evidence from Dhaka, Bangladesh

This research evaluates induced travel demand with the construction of transport infrastructure, using flyovers as a case study. Induced travel demand is defined as an increase in travel as a result of any increase in the capacity of a transportation system. However, relatively little is known about the induced travel demand effects of flyover infrastructure in developing countries.This research endeavours to answer the question of whether the construction of flyover induces travel kilometers or induced trips. The objectives of this research are to estimate average travel distance and trip frequencies based on socio-economic and travel characteristics of flyover and non-flyover users; to measure induced travel kilometres and induced trips caused by construction of flyovers; and to model induced travel kilometres and induced trips. Using purposive sampling techniques, both an intercept survey and online questionnaire were conducted to collect the data from 1060 vehicle users who used flyover and non-flyover roads in Dhaka.An independent samples t-test estimated that there is a statistically significant difference between flyover and non-flyover users. Induced travel kilometres and induced trips made by these two groups are also reported. Using a linear multiple regression model, the study found that the number of trip frequency of flyover users is increased by 0.350 owing to a one-minute savings in their travel time. The findings of this research contribute to guide policies that include the effects of induced travel demand when constructing new roadway facilities, particularly in Dhaka and other cities in developing countries.

Causes of Delay in the Construction Projects of Subway Tunnel

The constructions of urban infrastructure are an important sector that provides remarkable ingredients for the economic development of modern cities. However, a large number of transportation infrastructure construction projects are delayed; therefore, those projects always exceed their original time and cost estimates. So construction delay has been considered as a recurring problem in the construction projects of urban infrastructure, and it adversely affects the time, cost, safety, and quality of construction. This paper is committed to investigating the time performance of subway tunnel constructions in China to identify the causes of delay based on the questionnaire surveys of 87 tunnel consultants and 91 contractors, and a total of 49 delay causes of tunnel construction are identified one by one in this study. It can be concluded from this study that the six most severe delay causes are national policy for subway tunnel construction, complicated geological conditions, payment delays by owners, award projects to the lowest bid price, shortage of advanced large equipment, and low productivity of laborers. There is a relatively reliable agreement between the tunnel consultants and contractors of 76.3% on the ranking of different delay causes.

Комплексные горные проекты на малоосвоенных территориях России: обоснование параметров реализации

Complex mining projects, as a rule, have significant economic and social impact on the territory, sometimes entire regions where they are implemented. Consumers of their implementation effects are population, government, buyers, lenders and other stakeholders. Therefore, development of transport infrastructure in integrated projects for development of mineral deposits should have state support, forms of which are very diverse. In Russia parameters of concession agreements for construction of transport infrastructure, carried out in conjunction with projects for development of mineral deposits, are not regulated or justified.Aim of the work is to develop an organizational model and justify parameters of concession agreement for construction of the railway as a key element of transport infrastructure necessary for successful implementation of the project for development of a large coal deposit in a low-developed region. Research methods are: strategic, institutional, investment analysis, modeling and forecasting methods.The article proposes an approach to justification of technical, economic and financial parameters of concession agreement implemented during realization of an integrated mining project. As a result of the study, a concession agreement model was developed for construction of railway section as part of an integrated mining project, including development of a deposit and construction of a mining and concentrating company.

Applied aspects of problems with efficiency of BIM technologies of motor transport infrastructure objects

Problem. The need to transfer to a new, digital format of almost all the processes of creating and operating of motor transport infrastructure facilities is quite obvious and officially recognized in most industrially developed countries of the world. Currently, well-known examples of continuous fragments of BIM technologies work with a single object model only on the platform of one manufacturer. Therefore, the solution to the problem of using the necessary or more effective functionality of platforms of other manufacturers is associated with the routine processes of data conversion or model reassembly according to their rules. This leads to the loss of important information or to its fragmentation into elementary components, which excludes the possibility of changing design decisions by methods effective for them. Goal. The purpose of this article is to consider the applied aspects of the problems of the effectiveness of BIM technologies of motor transport infrastructure facilities. Results. The necessity of transferring the activities of the country’s automotive industry to a new, digital format related to the need to resolve many organizational, legal, technical and other problems is substantiated. The inextricably linked process of improving the norms and rules of research, design, construction and operation of motor transport infrastructure will increase the demand for new, scientifically-based solutions for BIM technologies, as well as for qualified experts in the field of their development, implementation and practical application. The growing importance of scientific research and new training programs adapted to the digital formats of their future activities is also obvious. Originality. The article formulates the goals of the new provisions of the paradigm of information modeling of motor transport infrastructure objects, examples of the practical implementation of the new provisions of the paradigm in the geometric design of motor transport infrastructure objects. Practical value. Examples of solving the problem of integrating solutions of platforms of various manufacturers and an alternative method of reducing the risks of road accidents when tracing roads with variable speed curves VGV_Kurve are given.

Will land transport infrastructure affect the energy and carbon dioxide emissions performance of China’s manufacturing industry?

The energy consumption and carbon dioxide emissions of China's manufacturing industry accounted for 12.8% and 15.5% of the world in 2016, respectively. On the other hand, the construction of land transport infrastructure has become the focal point of the Chinese government recently. However, there is very little literature investigating the influencing mechanism of land transport infrastructure on the energy and environmental efficiency of the sector. Therefore, it is crucial and meaningful to study how the latter is affected by the land transport infrastructure to alleviate global energy and environmental issues. Non-radial directional distance function was used to calculate two indicators measuring energy and carbon dioxide emissions performance in this paper. The panel Tobit model was then applied to focus on factors affecting the performance. The results indicate that land transport infrastructure, economic growth, technological progress, energy prices, industrial structure have significant impacts on the energy and environmental efficiency of China's manufacturing industry. Different from the results at the national level, from a regional perspective, the development of land transport infrastructure in the eastern region plays a negative role in the performance of the manufacturing industry. Finally, some targeted policy recommendations are proposed to improve the policy design of the government.

Numerical Simulation and Spatial Distribution of Transportation Accessibility in the Regions Involved in the Belt and Road Initiative

The Belt and Road Initiative (BRI) is a Chinese strategy, proposed to strengthen the connectivity and cooperation among BRI countries. Under this circumstance, many transportation projects are planned to be carried out, which means the transportation accessibility evaluation is of significance in providing valuable suggestions for transportation construction. This research established a global transportation accessibility index (GTAI) model in the BRI region using raster data. Based on its gridded outputs, we conducted classification evaluation, autocorrelation analysis, and a geographical weighted regression model to explore the spatial characteristics of the GTAI distribution and its correlation with population density. The results show that: (1) most countries in Europe and the Middle East, western Russia, and eastern China enjoy high accessibility, while central regions (e.g., Central Asia and western China) have poor access to destinations; (2) the GTAI values are distributed as a spindle, where about 60% areas belong to the middle transportation accessibility region, mapped as a non-significant type; and (3) there is a positive relationship between transportation accessibility and population distribution, but their connection tends to be weaker as socioeconomic development increases. Finally, several policy implementations are provided: (1) give a priority to road or railway construction between China and Central Asian countries; (2) establish an innovative transportation system and introduce advanced technologies to enhance the exchange and cooperation among the BRI countries; (3) improve public transport management in well-developed regions, and introduce talents and strengthen transportation infrastructure construction in developing regions.

An Improved Indicator System for Evaluating the Progress of Sustainable Development Goals (SDGs) Sub-Target 9.1 in County Level

In order to assess the progress of the SDG sub-target 9.1 at the county level, the SDG indicator 9.1.1 (rural access index) and 9.1.2 (passenger and freight volumes) were implemented in Deqing County, China to explore the fitness-for-purpose of these indicators for county level evaluations. It is found that the country-oriented indicator system has some localization problems and cannot fully reflect the connotation of the SDG sub-target 9.1 when used in the county level. An improved indicator system was built by modifying the SDG indicator 9.1.1 and adding three more indicators (namely the road density, accessibility, and total postal business). The analysis of the calculation process and results showed that the improved indicator system can solve the problems arising from the original SDG indicator when applied in the county level. The modified resident access index can eliminate the dependence of the original indicator 9.1.1 calculations on urban-rural boundary data, and takes into account the urban vulnerable groups such as urban villages residents. While the road density and accessibility can be used to measure the quantity, quality, and connectivity of the road and the reality of the residents to obtain the road, which enables the indicators to reflect the necessary details of the level of the transportation infrastructure construction. The total postal business can help the SDG indicator 9.1.2 reflect the relationship between the transportation infrastructure construction and the development of the economic and people’s livelihood.

Problems With Developing a Transport System in the Siberian Arctic

ABSTRACT The article considers a range of issues related to the development of transport in the Siberian Arctic territories of Tyumen and Krasnoyarsk. It describes two main transport achievements in the Tyumen Arctic: the Northern Sea Route (NSR), which has acquired new importance for the transport of oil and liquefied natural gas, and the continuing construction of ground-based transport infrastructure—railways and year-round paved roads. The article also describes several shortcomings in the transport system of the Krasnoyarsk Arctic due to the presence of mostly seasonal routes dominated by river and sea transport, the lack of alternative transport schemas, and an extremely high level of transport costs. An analysis is given of the priorities and functions of the Northern Sea Route and its increasing importance as a transport-logistics provider for major oil, gas, and other natural resource projects and the export of raw materials from coastal areas to foreign and domestic markets.

Therefore, problem solution demands further scientific and methodical development.

Energy and economic impacts of China's 2016 economic investment plan for transport infrastructure construction: An input-output path analysis

This paper builds an input-output model to analyze the energy and economic impacts of the 4.7 trillion-CNY investment projects of the " Three-Year Action Plan for Major Construction Projects of Transportation Infrastructure ", which was launched by the Chinese government in 2016. The results show that, from 2016 to 2018, the investment plan could increase China's GDP by 2.39%, 1.30%, and 1.24%, respectively, and the country's energy consumption by 3.98%, 2.35%, and 2.40%, respectively. The top five production sectors could contribute 55% of the GDP growth induced by the plan, and the top three sectors could contribute 83% of the energy consumption growth, indicating that the impact of the investment plan centers mainly on a limited number of sectors. From the view of supply chains, the 20 paths with the largest GDP contribution cover approximately 47% of the GDP growth induced by the plan, and the 20 paths that consume the most energy cover approximately 32% of the energy consumption growth. In these paths, the construction industry is the dominant demand sector, whereas the industry of nonmetallic mineral products, the industry of production and supply of electricity and steam, and the industry of smelting and pressing of metals are the primary supply sectors. In the future, the Chinese government should pay more attention to indirect energy consumption related to the construction industry, and policymakers will also need to set up more effective energy conservation policies for the upstream sectors of the construction industry, such as the sectors providing cement, glass, and steel. • Estimate the energy and economic impacts of China's three-year investment plan for transportation infrastructure. • Identify critical supply chains for the energy consumption and economic changes induced by the investment plan. • Propose several policy recommendations on reducing energy consumption in the construction industry.

RETRACTED ARTICLE: Assessing the influence of highway and high-speed railway construction on local climate using Landsat images in karst areas

Large-scale transportation infrastructure construction in ecologically vulnerable areas such as the karst region of Southwest China requires estimation method for better project design. This research was carried out on a four-lane highway (the Guilin-Guiyang highway, G76) and a two-lane high-speed railway (the Guilin-Guiyang high-speed railway, GGHSR) in karst areas in Guizhou and Guangxi provinces. The highway and high-speed railway were constructed in the 2010s and covered by Landsat images whose multispectral information could be used for research purposes. In this study, the severity of the impact and the CO2 emissions from the G76 and GGHSR construction were evaluated. Landsat images and field meteorological measurements were applied to calculate the surface functional parameters (surface temperature and surface wetness) and heat fluxes (latent, sensible and ground heat flux) before and during the highway and high-speed railway construction; the amount of CO2 emissions during the G76 and GGHSR construction were determined by using budget sheets, which record the detail consumptions of materials and energy. The results showed that the decrease of water evaporation from the highway and high-speed railway construction can reach up to 26.4 m3 and 20.1 m3 per kilometer, which corresponds to an average decrease in the vegetation cooling effect of 18.0 MWh per day per highway kilometer and 13.7 MWh per day per high-speed railway kilometer, respectively. At the meantime, the average CO2 emission densities from the G76 and GGHSR construction can reach up to 24813.7 and 36921.1 t/km, respectively. This study implied that extensive line constructions have a significant impact on the local climate and the energy balance, and it is evident that selecting and planting appropriate plant species can compensate for the adverse effects of line constructions in karst mountain regions.
