The paper analyzes the current guidelines of European Union on deployment Intelligent Transport System, as well their importance for development Croatian transportation system. crucial problems modern transport and traffic are indicated as: congestions congestion costs, harmful emissions in road transport, fatalities, etc. state System Croatia is presented based infrastructure, telematic industry, other supporting activities (including scientific research, educational activities,...

The basic principle of optimal traffic control is the appropriate real-time response to dynamic flow changes. Signal plan efficiency depends on a large number input parameters. An actuated signal system can adjust very well conditions, but cannot fully stochastic volume oscillation. Due complexity problem analytical methods are not applicable for use in real time, therefore purpose this paper introduce heuristic method suitable light optimization time. With evolution artificial intelligence...

Travel time is considered the most useful travel related information as it best indicator of level service on road stretch and completely understandable to all users. Various technologies for measuring traffic flow parameters provide optimal background implementation data fusion schemes gain maximum accuracy from combination available data. The objective knowledge predicted departure based two outdated accurate measurements. In this paper a new simple algorithm proposed short‐term highway...

The calibration procedure for traffic simulation models can be a very time-consuming process in the case of large-scale and complex network. In application Evolutionary Algorithms (EA) such as Genetic (GA) Particle Swarm Optimization (PSO) models, objective function evaluation is most step problems, because EA has to run calculate its corresponding value once each set parameters. main contribution this study been develop quick parameters driving behavior using parallel computing techniques...

Dispersed settlement areas (e.g., Slovenia) result in lower development of fixed public transport lines and thereby car-dependent lifestyles. To avoid congestion inside the cities on highways these areas, shared mobility modes e.g., carpooling, is one effective solutions, increasing occupancy personal vehicles. However, passenger pick-up drop-off locations still remain an important challenge for carpool users officials. As a collection point we can consider “park pool (P+P)” lots near...

Highway operators around the world are using automated vehicle identification (AVI)-based techniques as a technological input for travel time estimation on highways. Various AVI technologies provide various measurement samples: some of them able to identify only personal cars (e.g. tolling tags), while others mixed samples all classes license plate matching). As adequate information times should concern cars, influence heavy vehicles (HVs) be eliminated from samples, which is not feasible...

Summary The paper introduces an optimal control method for traffic management with variable speed limits. It consists of flow dynamics prediction a non‐linearized Lighthill–Whitham–Richards macroscopic model, introduction cost functional, which enables stable shockwaves optimization, and numerical implementation the optimization process differential evolution. overcomes discretization issues provides limits that are in general not limited to small number successive discrete points, i.e....

Development and wide use of route guidance systems lead to the need for suitable digital maps that can be used some advanced applications. Sufficient accuracy road geometry with emphasis on centerline positions curvature is crucial. In this paper presented a method finding from raw GPS data. The approach consists few processing steps. First it necessary fit data each section using B-splines, generate equidistant vertices polyline fitted curve. Then follows appliance stereographic projection...

Most of the microscopic traffic simulation programs used today incorporate car-following and lane-change models to simulate driving behaviour across a given area. The main goal this study has been develop an automatic calibration process for parameters using metaheuristic algorithms. Genetic Algorithm (GA), Particle Swarm Optimization (PSO), combination GA PSO (i.e. hybrid GAPSO PSOGA) were during optimization stage. In order verify our proposed methodology, suitable area with high bus...

Roundabout capacity estimation has been the subject of several types research in recent decades. Most analyses are based on empirical or analytical models (e.g. gap acceptance theory) considering various kinds conflicting flows, namely entry, circulating, and exit-ing flow. The drivers exiting flow either obey traffic rule (use right-turn indicator) disobey (do not use indicator). Accord-ing to reviewed literature, impact these driv-ers roundabout studied a greater extent. Therefore, this...

This paper presents the estimation of nine types utility function parameters for application in EVA mode choice model city Ljubljana, Slovenia. Four different modes (private car, public transport, bike and walking) five purposes (work, education, shopping, leisure other) were taken into consideration. first design Stated Preference survey, then a brief review model, functions method. The final log-likelihood enables comparison functions. results show that absolute differences among most are...
