Editor's Notes
- #49: O These are various data sources for OASIS.
- #50: O This slide shows what other people said how important data is.
- #51: Vehicle Detection System includes ¡°inductive loop detector & video mage vehicle detector¡±, which collects traffic volumn, speed and occupancy rate data. In KE, we currently have 3,118 units of VDS (approximately 1 VDS per 1 kilometer) This table shows an example of sample data set.
- #52: TCS - We have 256 TG, including open and closed systems There are about 3.4 million trip data collected daily Travel time data between tollgates for individual vehicles are collected. This is example of data set..
- #53: This is Hi-Pass: which is Electronic Toll Collection System (which is similar to EZPASS in United States). ??? ??? . This is an example of dataset
- #54: AVC stands fro Automatic Vehicle Classification, which can collect traffic volumn data by different vehicle types. We have 248 units total. The system has ability to classify 12 different vehicle types.
- #55: We have 2,237 CCTV units total in KE. Because of the vast amount of data storage requirement, we only archived top 100 congested area data. The video is archived 10 second length of video clip with 15 min intervals You can query or related with existing traffic data.
- #56: Incident data are really important to understand the certain pattern of traffic data. The location was recorded at milepost level on the highway. The incident data can be related and linked with exsiting traffic data.
- #57: Variable Message Sign. As you can see on the slide, it show the text message for specific time and locations. It provides invaluable information to understand the situation.
- #58: Weather information is really important understanding traffic conditions or perfomance. The information can be linked and related with other traffic information.
