This study presented a method of real-time traffic condition identification based on the fuzzy c-means clustering and travel time prediction on urban expressway. The traffic flow characteristics of expressway were analyzed and the traffic flow states were divided into four classes. Then the fuzzy c-means clustering technique was used to classify the sampled historical data and the clustering ce...

Urban congestion is a serious and worsening national problem, one which is receiving increasing attention from transportation engineers, planners, and researchers, as well as other local, state, and national officials. Urban freeways, which carry nearly 30’% of all traffic in urban areas, are particularly affected by growing urban congestion. In 1983, about 557. of urban freeway travel during t...

Currently different categories of traffic analysis tools exist. Among them simulation models can be marked as one of the most powerful approach to do traffic analysis researches. In classical literature simulation models are divided on macroscopic, mesoscopic and microscopic models. Microscopic and macroscopic modelling are well known and widely used, but both of them have disadvantages and lim...

In this paper we propose a dynamic Stackelberg game-theoretic model for urban freight transportation planning which is able to characterize the interaction between freight and personal transportation in an urban area. The problem is formulated as a bi-level dynamic mathematical program with equilibrium constraints (MPEC) which belongs to a class of computationally challenging problems. The lowe...

Due to several reasons, changing conditions in the environment do not always lead to changes in the traffic control units. The hypothesis of this research is that it may be useful to make use of self evaluating and self organising intelligent (urban) traffic control systems. In this research we focus on the applicability of autonomous intelligent agents within urban traffic control (i.e. traffi...

I recent years there has been a growing concern over the congested conditions of our urban highway facilities. The continuing escalation of adverse driving conditions in major urban areas has generated a feeling of discontent among automobile owners and transportation planners alike. One major factor that has contributed to this feeling of dissatisfaction is the rapid pace with which many of th...

The paper outlines the objectives and approach along with simulation results of the recent extensions of the traffic signal control strategy TUC (Traffic-responsive Urban Control). Based on well-known methods of the Automatic Control theory, TUC allows for the traffic-responsive coordinated signal control of large-scale urban networks aimed to be particularly efficient under saturated traffic c...

Original scientific paper Urban road intersections are bottle-necks of urban road networks, and the traffic organization optimization of intersections is the crux to relieve urban traffic jam. After analysing the features, applicable conditions and functions of the intersection channelization design, the basic procedures based on traffic survey, channelization design of the intersections and as...

the study of regional variations and the anthropogenic contamination by trace toxic elements of soils is very important for environmental planning and monitoring in urban areas. soil, sediment and rocks of urban areas of kerman studied to assess the degree of pollution by trace elements as a consequence of anthropogenic sources. 37 samples were collected and analyzed by icp-ms for 29 elements. ...

Video analytics is emerging as a high potential area supplementing intelligent transportation systems (ITSs) with wide ranging applications from traffic flow analysis to surveillance. Object detection and classification, as a sub part of a video analytical system, could potentially help transportation agencies to analyze and respond to traffic incidents in real time, plan for possible future ca...
