The lower the posted speed limit the higher the percentage of non-compliance rates which means that the compliance increase as the speed limit increase.

Nonetheless, motorcycle crashes have contributed more than 50% of the total number of fatalities due to motor vehicle crashes. High numbers of fatalities in motor vehicle crashes are a significant concern to Malaysia. On average, the number of fatalities increased by 4% every year. To address this problem, more intervention shall be taken to reduce motorcycle-related motor vehicle crashes. Passenger vehicle is the most frequent crash partner of motorcycle in Malaysia, thus, the characteristics of this kind of crashes shall be studied holistically to understand the contributing factors to crashes involving passenger vehicle and motorcycle. To achieve the objectives, this study has analysed 55 cases of crash involving motorcycle and passenger vehicle, which are obtained from in-depth crash investigation process from June 2016 until July 2017. The in-depth crash investigation has collected and analysed vehicle and site parameters including the crash configuration. It was found that the passenger vehicle was at fault in more than 60% of the investigated cases. The crashes mostly occurred whenever the passenger vehicle was changing lane to the left and was making a right turn in the junction. This indicated that the passenger vehicle drivers were unaware or overestimated the distance between the motorcycle and their vehicle. Therefore, new technology, which can detect the position and distance of motorcycles around the passenger vehicle, can possibly alert the driver from making inaccurate decisions while attempting to change lane or making a right turn. \u0000 \u0000 \u0000","PeriodicalId":286928,"journal":{"name":"Journal of the Society of Automotive Engineers Malaysia","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134588509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is done on the contact performance between tyre surface and asphalt pavement in hot and humid Malaysia climate, with the application of Finite-Element Method. In maintaining or increasing the safety features of tyre, several parameters such as rotational speed, vehicle weight, tyre-road contact friction will be studied through computer simulation. It is estimated that increment of loading, surface contact between tyre and road pavement will increase, thus increasing the frictional contact.

Besides, the suspension plays an important part in enhancing the passenger ride comfort. The suspension will make sure that the tire is always contacted with the road for a better grip and braking. Conventionally, passive suspension has been used in car manufacturing that leads to huge vibrations that affect the ride quality. This is because ride comfort of passengers gets affected by overshoot and settling time of vehicle under vibration. Therefore, a good controller design is required to minimize the vibrations. In this research, an active suspension of quarter car model that considers only vertical movement is utilized in the suspension system. This paper presents a Linear Quadratic Regulator (LQR) method to enhance the vehicle ride comfort towards the vibration of the suspension system. The control design approach is then compared with the classical control which is the Proportional Integral Derivative (PID) that is set as a benchmark control. The results for both controllers are evaluated through simulations in MATLAB and Simulink Software. Other than using the passenger vehicle parameters, the parameters of bus are also tested into the system to investigate the vehicle performance by taking the bumps and road pavements as road disturbances. The results obtained from the simulations show that the responses of the quadratic based approach give the significant improvement in minimizing the vibration and fast settling time compared to passive and PID control. \u0000 \u0000 \u0000","PeriodicalId":286928,"journal":{"name":"Journal of the Society of Automotive Engineers Malaysia","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114250534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
