The knowledge of temporal traffic patterns can help road users reduce their travel times by altering their departure time to avoid traffic jams at high traffic spots. This paper proposes an approach to help road users understand the temporal traffic patterns of a road segment with CongestionGrid, a platform for temporal visualization of congestion data. CongestionGrid highlights temporal patterns with respect to time-of-day and day-of-week by spatially arranging them in a grid as seen in Figure 1. The traffic states are represented by red, yellow, and green, which represent high traffic, normal traffic and low traffic, respectively. CongestionGrid allows users to explore the temporal traffic patterns by viewing the congestion data of a certain week or an aggregation of data over a period of time. We demonstrate CongestionGrid using congestion level data collected from 356 unique road segments in Bangkok over a period of 5.5 months.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129387009","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}

Based on the use of smart phones as tracking device, the proposed approach has the ability to track vehicles automatically in realtime through our tailored made application without requiring external power in an 8 hour operating period. In addition, a customized map transformation is proposed in order to cater for areas where location is not available through standard map services such as Google Map. These features are well suited for small scale vehicle tracking service with bus stops that are closely located such as exhibitions and conferences. The proposed system has been successfully deployed in an annual exhibition, NAC 2013 held at Thailand Science Park. Quantitative and qualitative studies have been carried out in order to evaluate the proposed system. The results have shown that our system provides reliable location update through the customized map as well as satisfying our participants with positive feedbacks.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124737293","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 historical documentary films are also employed distinction ambient sounds to simulate the ancient atmospheres in which do not exist in the current time. This type of sound is one of very important factors in the film industry production because it helps to create the visual imagination. However, the Thai film industry has borrowed the ambient sound from the international sound effects which are ready-made sounds in a sound library. The way of sound borrowing is caused to the low sound quality in the film because it lacks of many sound components which are necessary to construct the identities of a realistic local sets, and a recording situation of an actual environment. It, moreover, causes easily noise in the sound quality. Therefore, the author would like to propose a new framework of the ambient sound design, to create an ancient sound ambient for the film scenes through a synthesis process of sound design. By framing the ambient sound design concept, this paper focuses on the Thai north documentary film, Ancient Lanna Kingdom.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123021403","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}
