“…Vehicle emissions are a major source of pollution [3,28,29], and so carbon dioxide emissions should be part of any performance evaluation model [30]. There are several technical considerations that can reduce emissions and improve safety [31][32][33]for example, the COVID-19 lockdown improved air quality [34].…”

Traffic congestion problems have dramatically esca-lated with the increasing volume of vehicles, pedestrians, and cyclists in the face of limited road capacity. This re-search aims to reduce the time road users spend in the system (school-zone area) and improve the efficiency of the process of dropping off and collecting children from a crowded school area. The study integrates discrete-event simulation (DES) and multi-criterion decision-mak-ing (MCDM) techniques to comprehensively evaluate the proposed alternatives to select an optimal solution based on many performance measures. A real-world case study of the traffic and congestion problems experienced by parents when they drop off and fetch their children from school during peak hours is presented. A heuristic algorithm was developed to simulate the random and un-predictable behaviour of road users. A cost-benefit anal-ysis considered the impact of waiting time, traffic den-sity, number of accidents, additional fuel expenses, and emission reduction. The technique for order of preference by similarity to ideal solution (TOPSIS) and preference selection index (PSI) methods were utilised to select the most appropriate option for parents. The study found that the integration of simulation techniques with MCDM methods could efficiently solve traffic problems.

“…Air pollution in Kuala Lumpur and Yangon is heavily influenced by urban expansion [23,24] which directly increases pollutant emission from transportation [25][26][27]. For the anticipation, a better integrated and sustainable transportation system must be employed with cleaner fuel and a cutback of vehicle numbers.…”

Best Practices of Capital City Relocation in Various Countries: Literature Review

et al. 2021

Capital city relocation issue is currently emerging due to the condition and problem Indonesia encounters. Study toward some cases of capital city relocation could be crucial input for analysis and comparison. This paper aims to review capital city relocation examples. Literature review shows there are variances in background and driving factors internally or externally, and infrastructure needs for city development. The driving factors consist of environmental pressure, pollution, urban heat island, housing, urban sprawl, and disaster. The infrastructures required for the development of a new capital city are information and communication technology (ICT), physical infrastructure, transportation, and open green space. From the analysis, Myanmar’s Yangon to Naypyidaw relocation and Malaysia’s Kuala Lumpur to Putrajaya relocation are the best practices in capital city development that boosts new activities and urban extension. Burma shows the infrastructure’s role in development of a new capital city and Kuala Lumpur reveals how ICT implementation helps to establish a new capital city. This paper is expected to fill the research gap from previous research in terms of reviews related to the need for ICT in capital city preparation. This indicates that this paper has followed the trend of ICT advancement. The next research and publication will strengthen the use of ICT as one of the variables.

“…A steady growth of vehicle population in developing Asian cities induces heavy traffic congestions that disproportionately increase emissions of toxic pollutants. Accordingly, the large on-road vehicle fleets are reported to be the leading causes of ambient air pollution in big cities (Huy et al 2020a;Kim Oanh et al 2018;Phuc and Kim Oanh 2018). For example, in Vietnam, during the period of 2005 and 2015, the number of total in-use vehicles had increased by almost 3.5 times (OICA 2016).…”

A monitoring campaign, the first of this kind for a heavy traffic urban area of Vietnam, was conducted which generated nearly 200 daily filter samples of PM 2.5 , PM 10 , and black carbon (BC), 1300 online hourly PMx (PM 10 , PM 2.5 , and PM 1 ), 900 hourly/ bi-hourly BTEX data, 700 h of traffic counts, and online meteorology records. PMx and BTEX levels show large horizontal gradients across this small urban area of 300 m width suggesting that the pollution data should be generated with sufficient spatial resolutions for assessment of the exposure and health effects. This paper focuses on analyzing PMx with reference to the previously published BTEX to provide a more complete picture of the traffic-related pollution in the area. Spatio-temporal variations of pollutants are analyzed in relation to traffic flows and fleet compositions, weekday-weekend effects, local and regional meteorology. PM 10 and BTEX levels had larger variations between the sites indicating their stronger associations with the traffic activities than the finer particles. Twenty-four-hour (24 h) PM 2.5 levels ranged between 19 and 191 µg/m 3 with high PM 1 /PM 2.5 ratios of above 0.8 at ambient site (AA) and above 0.7 at roadsides. Multivariate relationship analysis (PCA) for the bi-hourly datasets of meteorology, traffic flows, and pollutant levels indicated overwhelming influence of onroad traffic fleet compositions on the roadside pollutants levels. At AA, PCA results showed a complex interaction between local emissions, meteorological conditions, and regional/long-range transport. Higher pollution levels were associated with the airmass types having the continental origin and pathways.
