INTRODUCTION Telematics is defined as the technlgy that utilizes the cmbinatin f telecmmunicatins and infrmatics fr the bidirectinal transmissin f data, in rder t update and remte cntrl [1]. The term telematics derived frm the cmbinatin f Telecmmunicatins and Infrmatics wrds. These tw sectrs, applicable t wireless technlgies and cmputer systems cmprise the science f telematics. Recently, the use f the term telematics is cnnected clsely with the GPS (Glbal Psitining System) in cmbinatin with the use f cmputers and wireless telecmmunicatins fr management f vehicle fleets. The adptin f this technlgy facilitated much f the develpment f the Internet, it became mre affrdable and ecnmical fr the user [2]. One f the sectrs where telematics is applicable is the vehicle psitining assciated with fleet management f urban transprt. The term telematics is ften identified with the management f a fleet, since this is the widespread use f this technlgy. With the use f telematics in a fleet f vehicles, the cntinuus mnitring f the psitin achieved vehicles, chsing the ptimal rute and anther set f advantages [3]. II. DETAILED DESCRIPTION OF STRUCTURE AND OPERATION OF THE INTEGRATED TELEMATICS SYSTEM (ITS) A. Integrated Telematics System (ITS) The Integrated Telematics System (ITS) is an Integrated Passenger and Fleet Management Infrmatin System, which is built and perated fr the Athens Urban Transprt Organizatin and mre specifically fr urban buses and the cmpany's trlley Rad Transprt SA by the Organizatin f the Athens Urban Transprt, the assciatin f cmpanies Intrasft Internatinal - Intrakat, which was awarded the prject f Urban Transprt Telematics thrugh Public Private Partnership.

BSS6D Circuit BSS6D undertakes the safe transfer f data frm the cntrller t the circuits f the LED screen and return errr data frm them. Additinally incrprating a sund generating system perates independently but is cntrlled directly by the central cntrller. The circuit incrprates BSSD wn transfrmatin units f type Pwer Switching DC-DC cnverters t generate the necessary perating vltages. 4. Athena GSM The Athena GSM circuit ensures the safe transfer f the cmmunicatin prtcl thrugh the mbile netwrk. There isn t autnmus and its functin is incrprated int the central cntrller perating system. The Athena GSM circuit incrprates wn transfrmatin units f type Pwer Switching DC-DC cnverters t generate the necessary perating vltages. 5. Hemera The Hemera circuit is a mnitring and prtectin circuit thrugh which passes the main system pwer supply t the pwers supplies. This circuit is integrated planning and running specially designed firmware. It filters the mains frm the prvider netwrk, insures against shrt circuits, integrates envirnmental cntrl system, cntinuusly reprts the status t the central cntrller and has the pririty rating t interrupt and restre pwer t the system if requested by the hst cntrller, r if it lses cmmunicatin with him. The pwer supplies are type AC-DC and DC-DC Switching, capable f accepting external pwer and t transfrm the necessary vltage f 5.5 Vdc, with which all the individual circuits. 6. frame / Shell prtectin f electrnic circuits The shell prtectin f electrnic circuits is a specially designed self-alleged cnstructin which is detached as a unit frm the frame, enabling the direct replacement f all cntrl circuits in minimum time. At the same time prvides the necessary envirnmental prtectin t them. In summary, the frame prvides the necessary supprt and prtectin fr the entire system and the inner shell prvides internal islatin circuits [6]. III. FUTURE EXTENSIONS AND APPLICATIONS - INTERACTIVE BUS STOP The existing telematics system upgrade capabilities and develpment f new services and applicatins, such as the implementatin f a netwrk f Interactive Bus Stps, which will be screens placed next t the bus stps. These bus stps will ffer the pssibility f interactive cmmunicatin t the passenger with the ITS. This infrmatin will be ffered in graphic tuch envirnment and will include additinal infrmatin than can be fund in printed frm at the bus stp. The infrmatin ffered in each Interactive Bus Stp will cntain line infrmatin, bus stps infrmatin and ptimal rute. At each Interactive Bus Stp will be interactive utdr tuch screen that will have anti-vandalism prtectin. The Interactive Bus stp will have cnnectin thrugh 3G mdem with CMS. The mnitr will be cnnected t the cmputer and will take data frm the db server which will be implemented infkisk web server t a virtual server. On the tuch screen will be html5 and css3 technlgy website that the public will have access t all cntent and perfrm queries in infrmatin resurce f the central system. The implementatin f these functins can be based either n a tablet-type cmputer r a cmputatinal set with discrete cpu and tuch screen as shwn belw.

The infrmatin line will include the display f line with the bus stps n the map, and the line scheduled departure prgram. Available will be thrugh tuch selectin f any bus stp line s that the user can be transferred back t the staging infrmatin. Optimal Rute Thrugh ptimal ruting tl, the user can select departure pint and end-pint and transitin preferences as the maximum walking distance and the criteria based n which the system will return results. The start r finish selectin methds will be: Select pints f interest. Intrductin and Divisin number. Bus stp select frm list. Chice f the bus stp will be the user at this time. The criteria which the system takes int accunt will be: Maximum walking distance. Results in terms f minimum distance. Results in terms f the minimum time. The results f the ptimal rute search will return step by step and the display n the map with the rutes which the passenger will have t fllw t reach its destinatin. The display will be a large map in the applicatin center and verbal descriptin f each step f the path left f the map. Selecting each step f the verbal rute descriptin, the system will display next t the map the rute which will be fllwed. IV. CONCLUSION In the abve paper was carried ut the study f an Integrated Telematics System (ITS), which is an Integrated Passenger Infrmatin Systems and Fleet Management fr Rad Transprt SA with Public Private Partnership. Specifically, fr the installatin f a netwrk f 1,000 «smart» bus stps acrss Athens Urban Transprt Organizatin service area, fr a ttal perid f 12 years. This telematics system, perating since March 2016 in Athens, has cntributed significantly t the imprvement f services ffered t the traveling public, but als t ptimize the peratin f the Agency. The telematics system at smart bus stps infrms passengers abut the arrival times f buses. The implementatin f Interactive Bus Stps netwrk will be able t ffer the pssibility f passenger interactive cmmunicatin with the Integrated Telematics System (ITS). This infrmatin will be ffered in graphic tuch envirnment and will include additinal infrmatin than can be fund in printed frm the bus stp. The Interactive Bus Stps can be used fr the first time by the traveling public and nt nly. These innvative bus stps will prvide in real-time, rute-time infrmatin, they suggest the ptimal rute fr passengers as well as news f general interest, such as weather and current affairs. The ITS help imprve management f the mvement f buses and fleet f buses, in the mnitring f services and the ratinal management f staff and resurces. The ITS besides the many benefits available, prmtes the use f buses, reducing the use f cars, thus reducing cngestin, nise, accidents and reduce air pllutin. V.
