Introduction The time headway of vehicles is of fundamental importance in traffic engineering applications like capacity, levelof-service and safety studies. Further, the performance of traffic simulation depends on inputs into the simulation process and ‘accurate vehicle generation’ is critical in this context. Thus, it is important to define headway distribution pattern for the purpose of ana...

The existence of different types Commercial Vehicles (CVs) in the shared roadway affects traffic flow characteristics differently from other vehicles. Owing to uncertain placement and movement these CVs both longitudinal lateral directions, opportunities for lane changing overtaking by vehicles with lower maneuverability decrease, resulting formation platoons. study's primary aim is assess effe...

Real-time and accurate short-term traffic flow prediction is the premise and key of intelligent traffic control and guidance system. According to this problem, this paper put forward a prediction model based on multivariable phase space reconstruction and least squares support vector machine (LSSVM). First, the model confirms embedding dimension and delay time of the traffic flow, occupancy and...

Due to steady increase in traffic density on roads, the traffic phenomena become non-linear and complex. For the traffic engineers and policy makers to regularize the traffic flow, we need to explore the traffic behavior in detail. In the current paper, the usefulness of CA to traffic flow modeling has been determined. Also, some of the existing CA models have been extended to study characteris...

Congestions of the traffic flow within the urban traffic network have been a challenging task for all the urban developers. Many approaches have been introduced into the current system to solve the traffic congestion problems. Reconfiguration of the traffic signal timing plan has been carried out through implementation of different techniques. However, dynamic characteristics of the traffic flo...

Bonald et al. have studied insensitivity in data networks assuming a fixed route for each flow class. If capacity allocation and routing are balanced and the capacity of a given class is shared equally between the flows, the network state distribution and flow level performance are insensitive to any detailed traffic characteristics except the traffic loads. In this paper, we consider optimal i...

The work discussed in this paper consists of a statistical assessment of various finite difference schemes for approximating macroscopic models of traffic flow. Using VISSIM we simulated traffic flow on a section of a freeway with arbitrary characteristics. VISSIM is a traffic flow simulator that uses a microscopic model for traffic. By using data from a microscopic simulation, we are able dete...

road accident severity may be influenced by a number of various systematic causal factors. the weather and road accidents have a close relationship with each other and a number of methods have been proposed for measuring the risk of a road accident with rainy, foggy, and snowy weather and high winds. recent studies indicate that road collision rates increase during precipitation. the weather wa...

In modern cities, a gradual increase of motorcycles and other types of Powered Two-Wheelers (PTW) are observed as an answer to long commuting in traffic jams and complex urban navigation. Such increasing penetration of PTW creates mixed traffic flow conditions with unique characteristics that are not well understood. Unlike cars, PTWs filter between cars, have unique dynamics, and do not respec...
