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.

Extension Knowledge Base System and Its Application

Li Lixi,Li Jia

Strategic Study of CAE 2001, Volume 3, Issue 3,   Pages 61-64

Abstract:

Knowledge base system (KBS) is an organization to store and manage a lot of knowledge. Extension knowledge representation (EKR) based on extension theory is presented in this paper. Two key concepts of EKR are the described——formal semantic of EKR and the formal representation of contradictory problem solving. The basic element of the former is knowledge matter-element model. In addition, the Specific Extension Inference (SEI) corresponding to EKR is also reviewed. The feature of SEI is correlative inference, which has been implemented by computer. Finally, the feature and the frame of extension knowledge base system (EKBS) are proposed. EKBS uses EKR and is an excess of traditional KBS. It is composed of goal system, condition system, common knowledge base, categorized knowledge base, inference machine and knowledge base management system.

Human hip joint center analysis for biomechanical design of a hip joint exoskeleton Article

Wei YANG,Can-jun YANG,Ting XU

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 8,   Pages 792-802 doi: 10.1631/FITEE.1500286

Abstract: We propose a new method for the customized design of hip exoskeletons based on the optimization of the humanmachine physical interface to improve user comfort. The approach is based on mechanisms designed to follow the natural trajectories of the human hip as the flexion angle varies during motion. The motions of the hip joint center with variation of the flexion angle were measured and the resulting trajectory was modeled. An exoskeleton mechanism capable to follow the hip center’s movement was designed to cover the full motion ranges of flexion and abduction angles, and was adopted in a lower extremity assistive exoskeleton. The resulting design can reduce human-machine interaction forces by 24.1% and 76.0% during hip flexion and abduction, respectively, leading to a more ergonomic and comfortable-to-wear exoskeleton system. The humanexoskeleton model was analyzed to further validate the decrease of the hip joint internal force during hip joint flexion or abduction by applying the resulting design.
