Multimodal facilities are being built in a majority of urban areas to accommodate both motorized and non-motorized traffic. The resulting transportation system is susceptible to complex interactions between different modes and users. These complex interactions are hard to quantify and capture on a regular basis. There is a need to rely on a microsimulation platform to replicate such real-world scenarios and forecast future conditions. This study focuses on assessing the effect of heterogeneous traffic conditions involving multiple modes like light rail transit (LRT), walking, bicycling, and motorized traffic on vehicle delay at intersections using Vissim traffic simulation software. A 2.5-mile urban arterial corridor comprising of seven at-grade and two grade-separated signalized intersections along US-29 route in the city of Charlotte, NC, USA was chosen for analysis and modeling. Base simulation model was developed by replicating the traffic scenario for the year 2018 (without LRT and non-motorized traffic). External controllers like VisVAP and Viswalk were used to assign signal priority and model heterogenous traffic conditions. The vehicle operational performance of the corridor improved along the major street after the addition of the LRT. An increase in vehicle delay on the major street was observed with an increase in the non-motorized traffic. Contrarily, the operational performance of the cross-streets at at-grade intersections did not see any significant change due to the addition of non-motorized traffic. The proposed framework assists planners to assess the impact of adding a new transit system like LRT and associated non-motorized traffic on the urban corridor. © 2022

Growing population, rapid urbanization, and increasing travel demand emphasize the need for reliable public transportation systems and sustainable transportation planning. A reliable bus service fosters a more significant, satisfied, and committed base of users. This research focuses on examining the association between on-time performance (OTP) and road network, demographic, socioeconomic, and land use characteristics to identify relevant external factors for proactive and reliable public transportation system planning. The analysis was conducted at a bus stop level. Bus arrival/departure data from the Charlotte Area Transit System (CATS) was obtained. The road network, demographic, socioeconomic, and land use characteristics were captured within 0.25-mile and 0.50-mile buffers. Pearson correlation analysis was conducted to understand the association between OTP and road network, demographic, socioeconomic, and land use characteristics by day of the week and time of the day. The results show that OTP is associated with external factors such as the number of signalized or cul-de-sac/dead-end intersections, number of lanes, network density, population, income (median and total), and land use types related to residential and commercial/employment purposes within the bus stop vicinity. The findings provide vital insights for transit agencies to enhance scheduling, service and maximize benefits, effectively utilize available resources, plan, and provide equitable services to all riders. © 2023 The Author(s)

Mockup is a scale or full-sized model that used for demonstrating and evaluating the functionality of a design. It is only in-plemented in a large project that having similar room patterns to reduce the risk of poor design. This research is to identify the corelationship between the number of rooms (or the project size) and the mockup investment cost to find the decision-making point. The research methodology is to build the perspective picture of VIP in-patient rooms as the Stimuli approach and build the same realistic full-sized rooms as the mockup then applying the systematic research implication to learn and synthesize the results to investigate the functionalities, environmental perceptions and cost-benefits ratio in order to evaluate the corelationship between the cost effectiveness and the estimated optimum number of rooms. In addition, data collection from the same hospital staffs, patients, and other service receivers will be conducted by questionnaire survey and close observation. The data will be complied vis-à-vis the results from mockup and stimuli methods to establish the decision-making baseline.

distinctive human attribute such as age, sex, and cultural background posted much of the problems in the understanding of graphic representation. This research attempts to use pictorial icon in cell phone as a case study to reveal the age and cultural bias between age groups. Most of them are able to operate only the basic features. The study thus has an ultimate goal to discover an universally representation of iconic symbol, which would help enhance the learning ability of senior group in particular, and to improve the usage of other technological oriented appliances in general. Study in three features-complexity of iconic, the visual limitation of the aged, and the interpretation of iconic symbols. The first issue deals with the capability to learn new technology and the recollection. Next, deals with graphic icon visible format -simple, detailed and textual which include size and color. The final issue deals with the 2d/3d format, realistic/symbolic, and with/without textual display. The research found that respondents are proved to be equally able to learn complicated level as younger users. With reading glasses, they are able to visualize and understand simple icons as small as 5-10 mm. Complicated as 30 mm. Graphical icons with textual as 10-15 mm. Bright color for simple icon, cooler tone is for complicated ones. 2d is for familiar objects while 3d and realistic for unfamiliar ones. Textual representation could enhance the understanding of representation as well.

Recent literatures empirically proved that spatial arrangements, interior ambient environment and architectural legibility are features reflecting corporate distinctiveness. This study endeavors to examine the linkage between corporate strategic orientation and its environmental design as corporate identity, focusing on visual and spatial design features. The objectives of the research are to study factors determining the design which conveys the corporate strategies, to investigates clients’ perceptions vis-a-vis the existing corporate design and finally, establish the relationship between the environmental identity design and corporate strategies. Furthermore, the process within which the design is derived.

Prof. Ph.D. program in Multidisciplinary Design Research King Mongkut's Institute of Technology Ladkrabang Chalongkrung Road Ladkrabang Bangkok 10520 Thailand

The primary purpose of graphic map design was to determine the factors for each types of map that can meet the demand of the tourists who are different in their destination. The graphic map factors enable us to know the target group and type of map they used that provides the accurate information corresponding to their actual need. Methodologically, the simulation viewing questionnaires were used to examine the opinion and need of the tourists whose interest was different with the type of map they used. In case study, the sample included the foreign tourists in Bangkok territory. This paper examined the graphic map design factors that meet the tourist's need. The results are expected to be used as useful guidelines for map design that satisfies the tourists in context of Thai social and cultural environment that can be recognized at international level. It's not only useful to those tourists, but also to general people.

Procedia - Social and Behavioral Sciences 2010年 5卷 1232-1235页

作者： Nuchnapang Keonil Nopadon Sahachaisaeree Arch.D. Program in Multidisciplinary Design Research Faculty of Architecture King Mongkut's Institute of Technology Ladkrabang Chalongkrung Road Ladkrabang Bangkok 10520 Thailand Assoc. Prof. Ph.D. Program in Multidisciplinary Design Research King Mongkut's Institute of Technology Ladkrabang Chalongkrung Road Ladkrabang Bangkok 10520 Thailand

This paper investigates the thermal perceptual aspect from daily activities. The research uses the cases of small detached houses in Bangkok to examine the best manipulation of architectural elements to optimally provide thermal comfort in the Thai living context applying a multi-facet research methodology. Two aspects of design manipulation—the spatial arrangements and buildings feature—are examined towards the optimization modeling. The level of perceived comfort obtained from data analysis is used as input in the modeling program to be tested to obtain the model of comfort optimization strategy and to set the guideline of passive design for tropical climate.
