1 Site Visit Reprt ITS Center the University f Tky by Mhammad Aminian [Transprtatin Systems Engineering PhD Candidate e ] m.s.aminian@htmail.cm Within the curse f ur field trip t Japan, n the afternn f Friday, July 7 th, 2017, we visited the ITS center f the University f Tky. The visit fficially started by a relatively shrt intrductin by Prfessr Yshihir SUDA, the directr f the ITS center at a lecture rm f Institue f Industrial Sciences (IIS). Then afterward we visited Chiba experiment statin which was just attached t Institute f Industrial Sciences. This reprt intends t summarize the lecture presented by prfessr Suda and the subsequent tur f Chiba Experiment statin. T explanatins f this reprt are referenced t the slides presented by prfessr Suda, the leaflets f the ITS center, and ur field bservatin during the visit. Intrductin: Advanced mbility research center (ITS center) f the institute f industrial science, the University f Tky is established in April 2009 fr the prmtin f research and develpment f ITS-related subjects. The research center incrprates 16 prfessrs frm mechanical, electrical and civil engineering departments and 20 members frm gvernment and industry sectr. This research center aims t prmte research in the fllwing fields. 1. Advanced transprt system based n Autmated Driving 2. Design f scial mbility using Big Data 3. Integrated mbility design including rad and railway public transprtatin The research center cntributes t educatin by hlding special curse fr practitiners, ITS seminars and graduate lectures in the university f Tky. The curses aim t develp human resurces fr ITS, t deply ITS applicatins further in sciety, and t create next generatin f ITS systems using cutting edge technlgies frm all related fields. The researches f the ITS research center are cllbrative activites amng transprt engineers, vehice engineers and infrmatin cmmunicatin technlgy experts Prfessr Yshihir SUDA, the directr f the advanced mbility research center (ITS center) and the head f Chiba experiment statin, intrduced the aims, activities, and infrastructures f his respective rganizatin which are briefly described in the fllwing. 1

This was dne thrugh estimating reginal traffic situatin using ICT and presenting the frecasts thrugh a user-friendly and understandable web interface. The prject was meant t Build the stepping stne fr future scial implementatin.

This facility is called Chiba Experiment Statin r ITS P&R experiment field. The test statin incrprates several tests facilities which are briefly mentined in fllwing. Figure 5, the layut f ITS P&R experiment field 4.1 Prving Grund and Experimental Traffic Lights The prving grund has an asphalt pavement and can accmmdate different types f experiments related t autmbiles, mtrcycles, aircraft and thers. We can cnduct varius experimental research in the field f mechanical engineering, traffic engineering, ergnmics and acustical engineering. There is an experimental intersectin with traffic lights installed t reprduce an actual rad envirnment such as city rad and rail rad crssing. This allws us t cnduct experiments that are difficult t perfrm in the actual traffic envirnment. Intelligent Transprt Systems (ITS) research is initiated with the cllabratin amng industry, academia, and gvernment, t prmte new safe driving assistance system, autmated driving, and V2X related develpment. 6

The simulatr is used t carry ut experiments invlving dangerus situatins and requirements f cntrlling experimental cnditins. The driving simulatr has a 6 degrees f freedm mtin system and a visual system t respnd a view f large vehicles. Using the driving simulatr, Tky University experts are cnducting studies n HMI (Human Machine Interface) and evaluatin f scial acceptance fr the realizatin f autmated driving in bus and truck systems fr the next generatin f traffic systems. 360-degree screen Car navigatin system Turn table fr yw mtin x-y table fr adjustment f yw center develped by cllabratin with industries internatinally Figure 7, large vehicle driving simulatr 7

Using a full-scale test track (abut 333m in length), actual bgies and vehicle can travel n straight line, a transitin curve, a steady curve (R 33.3 m), railrad crssing and switching. Wheel/rail cntact patches are measured and abnrmal vehicle states riginating in bgies f track are detected. Mrever, using a 1/10 scale running platfrm with R 3.3 m steady curve a scale mdel bgie can be perated and investigated. Research is being carried ut n the effects f changing track r vehicle cnditins and n a nvel bgie running system and wheel rail triblgy including wet envirnment.

There is a real subway car and a bgie (truck) f a cmmuter train car, which were perated in actual cnditins, as well as a vehicle mckup and a scale mdel car. These vehicles are used fr research n frictin cntrl, cntact prblem triblgy in wheel/rail cntact, research, and develpment f new types f steering truck, tests n safety against derailment, study n space cmfrt, etc. Figure 10, the test subway car 9

The buses are designed t perate n fixed rutes fr shuttle services. These buses will remain under test and experiment f ITS center researcher at Chiba ITS P&R experiment field fr a while. The visin is t cver the first and last mile gap t Tky subway statins by autnmus buses befre 2020 Tky Olympic games. Figure 12, Navya autnmus buses at the ITS center lab 10
