Abstract

Purpose: Malaysia is one of the developing countries that facing high road accident in Asia. The most common accident happens is between motorcyclist and cars. A motorcyclist is 17 times more dangerous than passenger cars. Analysis shows the three main types of accidents in Malaysia is collision with passenger cars, collisions with other motorcycles and single-motorcycle accidents. Road accidents keep rising in Malaysia, because lacks of road geometric design consistency where the drivers make mistakes errors due to the road geometric features. Design/methodology/approach: The study was conducted at F0050 from km 21 until km 25. By using GPS (DG -200), the continuous speed profile data were using new analysis method to develop road design consistency profile of motorcycle and cars and determined the value of the index the integrated road design consistency (IC). Findings: The developments of consistency model are based on parameter: the bounded area between the profile and the average speed, standard deviation of speed along a segment. Hence, use ACAD software for develops consistency model’s profile. The integrated-consistency model is the impact of the speed profile on design consistency in traffic and safety evaluations. The highest areas of an accident at km 24 are justified based on the design consistency of the area and integrated design consistency model between of car and motorcycle is poor design. The study shows that crashes and fatalities are fully effected by traffic volumes but road design performances and driving behavior. Research limitations/implications: However, the traffic volumes are relatively low in the whole country regarding to the Movement Control Order (MCO) due to the pandemic COVID-19 since March 2020. In contrast to the reduction of the volumes, the number of crashes still shows relatively high. Therefore, it shows that crashes and fatalities are influenced by other factors. Geometric factors such as access point, tangent length, curve length, shoulder width, and lane width are influencing an operating speed profile for developed tangents and curves of motorcycle and cars. Practical implications: The result of this study can be used as references to solve accident problems in Malaysia. Paper type: This study is categorized as a case study.

Abstract

Purpose: This paper discusses what is social perception, social perception aspects of non-verbal communication, attribution, and impression formation, and also some suggestions on how social perception affected cultures. Design/methodology/approach: Describe your method here. This research is a literature study research. The first step was to collect literature relevant to the topic. The second step was data reduction, which is reduced data and chosen the main data. The third step was presented the data and the last step was concluded. Findings: Impaired social perception can have serious social consequences. For example, an adolescent boy might misread a girl’s sympathetic smile as a romantic invitation, and proceed to respond in a sexually offensive manner or a child might misread a peer’s teasing gesture as a threat and react aggressively. In these cases, the socially unsuccessful responses were not a result of inadequate social skills. Rather, they resulted from social “misreading”, that is, impaired social perception. Not surprisingly, the more we get to know someone, the more accurate we are at describing their traits and motives. Even when judging people we know well, however, the shortcuts we use sometimes lead to mistaken impressions. As these examples suggest, effective social perception contributes in important ways to social success, peer acceptance, and friendship. Research limitations/implications: This research is a literature review research. Further empirical research is needed. Practical implications: Results of this research can be used as references in appraisal on social perception about communication and psychology. Originality/value: This paper is original. Paper type: A literature review

Abstract

Decision support systems are part of computer-based information systems (including knowledge-based systems) that are used to support decision making within an organization or company. The decision support system provides a semi-structured decision, where no one knows for sure how decisions should be made. Recruitment of employee recruitment in PT.Waspada Medan always through some tight selection before set accepted as employees at PT.Waspada Medan. There are several criteria that must be owned by each participant as a requirement to become an employee of PT.Waspada Medan. To get the best participants then the PT.Waspada Medan requires a decision support system. In this study, the authors apply Multi-Objective Optimization on the basis of Ratio Analysis (MOORA Method) as the method to be applied in the application of decision support system.
