Detection of critical road roughness sections by trend analysis and investigation of driver speed interaction

Meltem SAPLIOGLU; Ayse UNAL; Melek BOCEK

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 4,   Pages 515-532 doi: 10.1007/s11709-022-0814-4

Abstract: Pavement roughness (IRI—International Roughness Index values) influence the stability of traffic movements both on intercity roads and urban roads. This study is to determine the exact locations of critical pavement roughness values that affect traffic motion stability and comfort in city centre highway arteries. Roughness data with 10 m intervals were collected on a 3140 m divided road containing three consecutive signalized intersections in the city centre arterial. These data were analysed using the distance-dependent Mann-Kendall trend analysis method and checkerboard model. The sections where roughness is important were determined at a 95% confidence interval. The results will show where future pavement improvements should be prioritized for municipalities and road maintenance engineers and will form a basis for the urban road management system.

Fuel type preference of taxi driver and its implications for air emissions

Feng WANG,Beibei LIU,Bing ZHANG,Jun BI

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 4,   Pages 702-711 doi: 10.1007/s11783-014-0665-x

Abstract: Natural gas became an available fuel for taxis in 2005 and had occupied a market share of 43.6% in taxi industry till 2010 in Nanjing, China. To investigate the energy replacement pattern as well as the pollutants reduction potential of the taxi industry, first, the fuel preference determinants of taxi drivers for their next taxis are analyzed. Results show that as an important alternative for the traditional gasoline, natural gas is widely accepted (75%) by taxi drivers. Different from the previous studies which focused on the early stage of cleaner fuel replacement, taxi drivers with various characteristics (such as age, working experience, and education level) are consistent with their fuel preference when they choose their next taxis. Result suggests that policies that concern consumers with specific characteristics may have little effects on the change of the market share, when the alternative fuel market has been developed well. In addition, the increased share of gas in the fuel market achieves a 7.2% reduction of energy consumption. Considering life cycle emissions, the following air pollutants, namely Greenhouse Gases (GHGs), carbonic oxide (CO), nitrogen oxide (NO ), particulate matters (PM) and hydrocarbons (C H ), gain 10.0%, 3.5%, 20.5%, 36.1%, and 26.4% of reduction respectively. Assuming all taxi fleets powered by natural gas with local policy intervention, the energy conservation and the five major air pollutant emissions could achieve the maximum reductions with 12.2%, 16.0%, 8.8%, 22.5%, 44.2%, and 49.4% correspondingly.

A large-current, highly integrated switched-capacitor divider with a dual-branch interleaved topology and light load efficiency improvement Research Articles

Sheng LIU, Menglian ZHAO, Zhao YANG, Haonan WU, Xiaobo WU,liusheng_0827@zju.edu.cn,zhaoml@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 2,   Pages 317-327 doi: 10.1631/FITEE.2000404

Abstract: Because it is magnet-free and can achieve a high integration level, the switched-capacitor (SC) converter acting as a direct current transformer has many promising applications in modern electronics. However, designing an SC converter with large current capability and high power efficiency is still challenging. This paper proposes a dual-branch SC voltage divider and presents its (IC) implementation. The designed SC converter is capable of driving large current load, thus widening the use of SC converters to high-power applications. This SC converter has a constant conversion ratio of 1/2 and its dual-branch interleaved operation ensures a continuous input current. An effective on-chip gate-driving method using a capacitively coupled floating-voltage level shifter is proposed to drive the all-NMOS power train. Due to the self-powered structure, the flying capacitor itself is also a bootstrap capacitor for gate driving and thus reduces the number of needed components. A digital frequency modulation method is adopted and the switching frequency decreases automatically at light load to improve light load efficiency. The converter IC is implemented using a 180 nm triple-well BCD process. Experimental results verify the effectiveness of the dual-branch interleaved operation and the self-powered gate-driving method. The proposed SC divider can drive up to 4 A load current with 5–12 V input voltage and its power efficiency is as high as 96.5%. At light load, using the proposed optimization method, the power efficiency is improved by 30%.
