MOLIT(Ministry of Land, Infrastructure, and Transport) has established NTIC(National Transport Information Center) for effective management of various kinds of transportations in South Korea and released several services that people can use. Gaia3D Inc., has involved in one part of mobile service which displays traffic status on roads, streets, and highways up on geographical map, making people easily check the status of traffc wherever they’re heading. Gaia3D Inc., will introduce not only the experience of implementing mobile traffic map service (iPhone App, Android App, and Mobile Web Client) showing traffic on roads, streets, and highways at NTIC using Squid Proxy Server, GeoServer, and SQL Server but also advanced architecture coming up in 2014. NTIC system collects all kinds of real time traffic data of all highways, routes, streets, and roads in South Korea and divides those collected traffic data into three colors in green, yellow, and red by speed. These colorized traffic data are mashed up with map data to service on mobile devices. Servers carry out tiling traffic map in every 5 minutes and clients receive and display those tiled data. This system aimed at tolerating peak times of two major holiday seasons in South Korea - Chuseok(Korean Thanksgiving day) and Seolnal(Lunatic New Year’s day) when almost 15 million people per day travel at the peakest dat and about 8 million vehicels are poured out to roads, streets, and highways, so the system should be designed to safely handle over 100,000 concurrent connections. The whole system is consisted of two Cache Servers with Squid Proxy, six Map Server with GeoServer, and three Database Server with SQL Server. Real time traffic information and road lines are managed in SQL Server and provided to GeoServer. Traffic map tiles are produced in GeoServer and are passed to Cache Server. The client is designed to request tiles via interface of WMTS(Web Map Tile Service) protocol with Time Tag. The very initail architecture designed in 2012 somehow managed to endure traffic loads at peak times, but had some problems, which was quite disappointing and unexpected results. In order to improve the system, we’ve mainly focused on the enhancement of scalability. Also, we’ve newly redesigned the system into seperating tile producing servers and managing static contents using NGINX web server.

on it is true that all by ABS and double by traffic that that 1 of the the at a
background is of for you avoid ratio anti ICI is that in the press but it was a centre is a measure on the day he collected in order to give away show South Korea and the and the size in the continent and they providing a commission to people I on the backgrounds of the
pros day and taxis and the requirements of the federal they want to do I Peru time Trafigura for mission to users to disperse traffic or major national holidays for example of the new year as the use of the state and to stop the is the pupil and to all the Thanksgiving but as those holiday season in Korea both 30 million people will go to visit the home pounds and of that amount is in the early Sixties percentile for the population of South Korea in the last innings best migration because the people to be interested in the traffic conditions and these days the most of the people how have was not also would be want to use the want to get more information across much not so
the briefly domain features of double by tracking surveys is ideas all their it is as if the words intricate would to mean in politics and is recalled that colour traffic beyond those grin column free traffic and red colour in contested the references to the is applied by road types and in the
shade and its abroad to traffic accidents decorations and the city based on the old Route
all of this is that after picture of tools about and the actually my company was in the 1 full had designed to distance system there was a company who originally designed to and but there were a lot of problems as you can see all it is a Windows based systems and there are on 6 6 2 sobered and them at the and 1 of the giant must 1st secret database and there is no cash server and a client recast 1 size the beach and a long time so there are not of course Crowborough so 2
thousand Euro avoiding the logic of the surveys so the their World War a users the and the expected and the cause of after of cash Asaba of same rogation information was a reportedly requested to the server because it and it just over so that they can to lie down at the time because of these problems are not of a customer a giant and the and the before 1 of the officers study has just proposed jacket
still intensities requires require the will also to brief period to stop in September to hours the to system improvement so the requirements be 1 of 4 of the 400 thousand images per day and the day changes they want to change database to go so what they with the head of the Yukos because at the time of their on not properly the benchmark decided to using officers is South Korea so we failed to persuade the customer and so our over some home we suggested the solutions like that you want above that means is that the system of the 2 should be redesigned and the system regarding maps should be redeveloped and in that time the proposed or maverick song more by side should be tied to answer the big across the server should be used as a cash server for improving their reusability and for 4 months and forest and although to a called Bailey the trophy inflammation and by the time for cash pile should be determined we use using W face and content by the time and cost on time and must be suggested making for the time at around in the back where every 5 minutes He
raised the UK data in 2 thousand 12 off it consists of Saudi server and their abilities and the excuse of a just over so making tool 5 or 6 5 2 5 6 high demand in the UK each a and there are 2 occasions over in front of them and they put cash maker at the cash is oversight to produce of dropping back to a time tigers in at the back and the cash makers using and for Moody's or on the road and present principle of costs which produced ties and as we developed to apply for while the act and a by page we are so redesigned the to automatically menial tracking that every 5 minutes and the public of the cash structure in to buy at the
time during the two of the season in 2 thousand 4 likely but the child was being stood by monitor this system and ICI over abroad to the about 1 million people download the about only during this season as a reserve deserving of summer successfully stable with was much better than previous assisting frantically speaking as a developer who was not 5 from by protested time at every 5 minutes or so unnecessary recast to had increased and response time cars until I got or as a traffic time As traffic piled long comprised of attention Rabbi so I that they see the that over 1 million time all the time that in every that could be updated in at the end of the day and vibrant and it's a problem solely to solve the problem temporarily for 9 10 rebelled England clients returns to just over made tracking the data dynamical in their for the connexion time that longer and than the number of connexions increase now sell in the UK to tourists Caillebotte but the key issue of all all of which the cash is of can to ship the data so for possessing increase the recast caches several should be added to here but adding more cash a summer on the stock victim even more observer of clothing to of extra suburb sold it called it because it is close to issue and then more conscious of earnings are more tests or a cast from the cash maker at the cash is oversight so of 0 8 roles in the room when it rose Aesculus of over and type with of burden of this system still the
suggested that the new strategy to cover the costs of a new all be persuaded the outward customer 2 Use posted yet again because which provides the faster special a party function with the and redesigned just over a car that was just 1 by 1 stand up to her and at the leader for myself with traffic data had not data and told candelabras was less than 4 gigabyte so meaning that data size was not that the big so the key to reduce the cost to the NHS to speed up the excess process so when adding caches over we chose memory is instead of this the other Whalley changes in the system to push pad attracting the data into cash is over this Land as shows
at the UC later this year the Week but it be or the physical the combined maps of a database and are so system generates is the fight the are heading for of was the judge and to think that time we weepily Kate they die in postgrads through under the posts for a secret and instead of catchy makers cash to Cerberus side we put the pyjamas and later the man and to views oversight new and with this the pensioners
manager of it has a major divided jobs for each just over could produce time there are being part of and a of jobs finished a pushed higher the trophy where their are into the issues over age pages of a book in Case of increasing the child which sold demand and the Web and you the servers only have a rude to produce tied trophy part the with data and or we can all do more by can be handed the only by Judge over the side and I don't have ONg may eventually side over so in case of increasing connexions the system can be survey by just cash Asaba here and with some of the duration of the pilot generation manager so the the ApJ picture is more Scalable and we have on
other ideas to reduce the filter along with the car periodically to be the updated of the idea that there is single because they are the changing the file containing traffic information it the fine if you believe for me a title at the World Cup of roles these updated and that it are so could be find a way for me piezo changes the Trafigura formation is about data the journey that as a song about a 8 idea is more effective to update the tax this chart shows the
reserve all been proven what improve the it is called here of 2 thousand 12 and this year As you can see the time to of big things interim over time generation has been shorter and 2 1 win at Old water and Robert all actually the developers say to me go out and it takes only 10 seconds to change that take 2 Update tainted the traffic information the service is now service this week during 4th was the conference is to stop high rubbishing in South Korea and now was to order the book by traffic it was the system there by Neil Back teacher has been smooth the survey now
those through the prise out we became to make sure that opens Australia says that the new cable into 2 camassia brought up in times of a performance now and we got confidence to persuade the customers into adopting the of associated with no worries and and think this prise at today's are case the case of doping officers to the idea specially by the public institutions that turns out for the US and there is a lot of cases in South Korea officers with this
experience but down it is he's so rich not develop pride that he is constructing will by over the top to service using just over and costs Chris occur at kidney disease of these are as good a shot that went in the kind of bad of fish in England 1 still eyes and Chile islands and that the members of this prise at the height of the technical you keep it in of those who did you have any questions please as using the getting into so
