In this paper, we propose a new multi-directional two-dimensional continuous model for urban traffic. It is called the NEWS model, since it represents system of four partial differential equations (PDEs) that describe propagation vehicle density in cardinal direction layers: North, South, West and East. The can be applied to predict traffic evolution on general network arbitrary size by knowing...

In recent years, numerous turbo-roundabouts have been built in many European countries. To date, there are no Italy and even the regulations do not provide for their implementation. Turbo-roundabouts considered ideal alternative to multi-lane roundabouts as they advantages. However, offer better operational performance only specific traffic flow distributions. This research used case study of a...

Traffic simulation is an often used tool in the study of traffic systems. A traffic simulation model consists of several sub-models; each handles one specific task in the simulation. These sub-models include, among others, car-following. This model controls the interactions with the preceding vehicle in the same lane. This paper compares and describes the car-following models used in the four t...

Microscopic traffic simulators are useful tools for designing, evaluating and optimizing transportation systems. In order for a simulator to accurately describe reality, the corresponding traffic model must be properly calibrated. However, the calibration can be rather difficult when the model is computationally expensive and has many parameters. To overcome these difficulties, Sensitivity Anal...

During the last century, there has been considerable economic growth and development of cities around the world. The growth has led to an expansion of car-ownership and ultimately increased congestion of the road network. Traffic engineers and transport planners have attempted to mitigate the consequences of congestion of motorways and freeways using a number of techniques. One of which has bee...

Introduction. Today there is an acute problem of increasing the number accidents involving personal mobility devices (PMD). A sharp increase in these vehicles on public roads poses a threat to both vehicle drivers and pedestrians. Materials methods . In this article, results evaluation traffic flow characteristics individual under different conditions with help road section modelling are presen...

Given the significance of transportation sector to economy a country, major companies and government-linked entities have invested in infrastructure services. Nonetheless, faces issues relating traffic congestion, energy consumption, environmental impacts such as air pollution carbon emissions. To address analyze these issues, current study employed microscopic modeling using AIMSUN software, w...

The prospect of automated mobility on-demand (AMoD) services in urban areas has highlighted critical challenges surrounding the sustainable development mobility. To address this gap, we created an improved simulation tool by combining SimMobility’s demand simulator with hybrid meso-micro supply model Aimsun Next. A realistic and city-scale examination AMoD using such advanced can limitat...
