1 ATSSS: An Active Traffic Safety Service System in Pudong, Shanghai, China Hangbin WU Tongji University, China The 14 th international symposium on Location based Services, Vienna, Austria

2 Outlines 1 Background 2 Objectives 3 Data collection 4 Service method 5 Applications 6 Acknowledgments

1 Background Vehicle accidents between 1970-2010 in China 1.

2. Most of the accidents were occurred at the intersections and the black spots of roads.

3 1 Background Vehicle accidents between in China 1. Most of the deaths in accidents were caused by illegal events, such as speeding, reverse driving, illegal lane etc. 2. Most of the accidents were occurred at the intersections and the black spots of roads. Speeding Main causes of accidents in China death Reverse driving Illegal parking Too many intersections in a short distance along high level highway are easy to lead accidents Causes lead to DEATH

4 2 Objectives Broadcasting database Voice, text and thumbnail Reverse driving events Events Detection Accidents upload Vehicle accident

5 2 Objectives Broadcasting database Voice, text and thumbnail Reverse driving events Events Detection Accidents upload Vehicle accident

6 2 Objectives Broadcasting database Voice, text and icon Reverse driving events Events Detection Accidents upload Vehicle accident

7 3 Data Collection Traffic data Event Type Time Location Lane Event black spots Real time video Event detection algorithm Installed in Traffic Police Department database Historical database Accident Pocket device Accident Type Time Location Lane Traffic status Estimated time Accident black spots

8 3 Data Collection Users position Location Direction Speed Satellite number SN Wireless communication database Historical database

9 3 Data collection - summary In this project, four types of data were collected yet. Type Time delay Contents Events Accidents 1-2 min 5-10 min Illegal lane, Reverse driving, Illegal astern, falling objects, etc. Accident type, loation, impacted lane, current traffic status, estimated time, etc Black Spots -- Location, type, etc. Users position 2-5 s Latitude, longitude, speed, direction, satellite number, SN

Latest traffic events Latest traffic accidents Distance analysis Correlation analysis

10 4 Service Method An server were installed in order to manage the database and map services. An App was developed for Android and ios users. Latest traffic events Latest traffic accidents Distance analysis Correlation analysis Temp database Relative events and accidents according to user s position Data push Position Navigation analysis Warning message

11 5 Applications Visualization system of Active Transportation Safety Service System (ATSSS) The detailed accident info will be recorded and uploaded by policeman in 5-10 minutes after arrived. Collision accident Latest accidents

12 5 Applications Visualization system of Active Transportation Safety Service System (ATSSS) An automatically events detect algorithm is applied to the captured videos. The events detected will be manually confirmed in order to enhance the reliability. The events will be stored in 1-2 minute. in-situ camera installed by police department Illegal lane events detected

13 5 Applications 位置安全行 App: an ios and Android app developed for the project, the Chinese name of App means LBS will provide safety driving. The functions including: positioning, navigation, POI search, Route management, Lane-level navigation, Black spot warning, traffic events warning, traffic accidents warning, etc. POI search

14 5 Applications illegal parking event warning example 1. The insitu camera captured the illegal parking event 2. Server pushed the warning message to mobile user Illegal parking vehicle Insitu Camera

15 5 Applications accident warning example Warning message relevant vehicle Position of accident

Therefore all the black spots were stored in the mobile phone.

16 5 Applications Black spot warning. As the black spots of Pudong are updated by the end of year. Therefore all the black spots were stored in the mobile phone. Lane level navigation. In this project, we also tried the lane level navigation in 15 intersections.

17 6 Acknowledgements The project is financially supported by the Ministry of Science and Technology of China through national high technology develop program, No. 2013AA12A206 Thanks Q & A?
