Floating car data present a cost-effective approach to observing the traffic state. This paper explores whether floating cars can substitute stationary detection devices (e.g., induction loops) for observers within traffic responsive control systems. A rule-based traffic control method at the local intersection level is proposed in this paper by utilizing the floating car data. The control method involves a threefold approach: link-level speed forecasting, data-driven traffic flow estimation, and split optimization. To estimate traffic flow, a multivariable linear regression model is developed by utilizing forecasted link-level speed, signal control variables, and link length as predictors. The method is tested using a controller (hardware)independent software-in-the-loop approach. Compared with the existing fixed-time control operating in Starnberg, Germany, the proposed method is able to improve the level of service of the signalized intersection when tested for different levels of market penetration of the floating cars. The findings underpin the use of floating car data in online traffic control applications; the benefits will increase with an increase in market penetration of floating cars. Overall, this paper presents a fully integrated technical system that is ready to be used in the field. The proposed system can be implemented at the tactical level of urban traffic-control hierarchy employed in Germany.

“…[16] SCOOT system is one of the most wide-spread systems utilized for traffic control; implemented at over 200 locations across the world [15]. In 1973 the British Transport and Road Research Laboratory -TRRL (Now Transport Research Laboratory -TRL) started with the development of the SCOOT system [17].…”

It is generally known that traffic safety is influenced by humans, vehicles, and roads. Nowadays, when new technologies have taken over a large part of the traffic industry, the selection of relevant software, whose competition is great, presents a big problem for the decision-maker. Intelligent systems, such as Motion, SCOOT, and SCATS, are used for the implementation of a control strategy in order to manage signals on the traffic network, with the goal of increasing efficiency and traffic safety. These systems operate on the demand-responsive principle and have logic for traffic optimization which represents their main difference along with the optimization subject and method of the system functioning. The research included consideration of mentioned differences, software, and hardware architecture that have a significant impact on the system’s functionality since the detector’s locations themselves depend on the optimization subject. The implementation benefits are considered through the existing world’s projects. Based on the obtained data, the criteria used for the comparative analysis of these three systems were defined, from the aspect of traffic safety.

“…Osnovna arhitektura sistema se sastoji iz dva nivoa: taktičkog i lokalnog. Taktički je predstavljen MacroBalance modulom koji proračunava okvirne signalne planove [27,28]. U početku je korišćen heuristički pristup, a kasnije genetski algoritmi.…”

“…Za davanje prioriteta JP-u se ne koristi model već skup logičkih uslova na lokalnom nivou (kao kod MOTION). Za offline simulacije se koriste softveri Aimsun2, NONSTOP i VISSIM [9,26,27].…”

Adaptibilni sistemi za upravljanje saobraćajem (ASUS)predstavljaju1. UVOD U današnje vreme veliki broj gradova se suočava sa problemima porasta, ali i promenljivosti transportnih zahteva. U skladu sa tim, gradske vlasti se sve više koncentrišu na najefikasnije moguće korišćenje raspoložive infrastrukture kroz napredno upravljanje saobraćajem. Rešavanje ovog problema bila je osnova za razvoj upravljanja saobraćajem u gradovima upotrebom računara i IT tehnologija, pa su kao posledica nastali različiti sistemi koji su izuzetno sofisticirani. Osnovni zadaci koji se postavljaju pred ove sisteme su povećanje efikasnosti, reagovanje na incidentne situacije na mreži, smanjenje troškova ažuriranja fiksnih signalnih planova i održanje visokog stepena bezbednosti.Adaptibilni sistemi za upravljanje saobraćajem (ASUS) predstavljaju veoma važan činilac modernih ITS platformi. Razvoj računara i novih tehnologija, omogućio je kreiranje ovih kompleksnih sistema namenjenih upravljanju radom svetlosnih signala duž koordinisanih koridora ili koordinisanih zona. Veliki broj sistema je svoj život započeo u vidu istraživačkih projekata, međutim danas ih veliki broj kompanija nudi kao komercijalne proizvode. Postoji veliki broj aktivnih ASUS širom sveta koji su instalirani na različitim lokacijama, funkcionišu sa različitom opremom, rade u različitim uslovima i postižu različite rezultate. Ono što je zajedničko za većinu sistema jeste nedostatak informacija o suštinskim detaljima načina rada, korišćenim algoritmima, modelima i ostalim elementima upravljačke logike.Proizvođači štite svoju intelektualnu svojinu tako što obelodanjuju samo određenu količinu i tip informacija koje se tiču ASUS i tako što kupcima ograničavaju pristup osnovnom kodu samog ASUS u određenoj meri. Iz navedenih razloga, stručna javnost i gradski organi koji se bave pitanjima saobraćaja se suočavaju sa poteškoćama kada je u pitanju detaljno upoznavanje sa karakteristikama sistema ili donošenje odluka o kupovini istog. Zbog toga je cilj ovog rada da
