The world has recently witnessed a great tendency towards rapid urban development. This has been accompanied by an increase in the population and a development in the uses of the land, which changes the reality of transport and increases its problems over time. The city of Mansour suffers from traffic jams in certain parts of its road network due to the increase in population and the shift in the...
Challenged by rising populations, modern cities are affected by the increasing effects of transportation such as congestion and greenhouse gas emissions. Collaborative route planning addresses this challenge by consolidating goods and optimizing transport routes to the customers within the urban area. This paper presents a modeling approach for collaborative route planning in supply chain simulation...
Autonomous driving in urban environments depends on the ability to interpret the current situation and to react accordingly. This means to continuously make decisions for certain comfort-optimized maneuvers under the constraints of traffic rules and feasibility. This work presents a novel, longitudinal driving strategy formulated as a discrete planning problem. Instead of designing an algorithm for...
Automated ground vehicles are becoming a reality for future deployment due to their potential improvement of safety, comfort or emission reductions. However, some challenges remain unsolved such as navigation in dynamic urban environments, where safety and comfort are paramount. In this paper, a novel speed profile generator, based on quintic Bézier curves, is presented. This approach permits to improve...
Interest towards the applications of ICT in public and private urban transport has grown significantly over the last few years. In the field of the user interfaces with transportation, however, continuous, highly context-aware, real time interaction can still be found only in a very limited number of cases, mostly in private transportation. One of the main issues in actually developing an assistive,...
In this paper, we aim to explore path following. We implement a path following component by referring to the existing Pure Pursuit algorithm. Using the simulation and field operational test, we identified the problem in the path following component. The main problems identified were with respect to vehicles meandering off the path, turning a corner, and the instability of steering control. Therefore,...
In this paper, we present a motion planning algorithm for autonomous navigation in highly constrained urban environments. Since common approaches to on-road trajectory planning turned out to be unsuitable for this task, we instead extended an A*-based planner originally designed for navigation in unstructured environments. Two novel node expansion methods were added to obtain smooth and accurate trajectories...
In classical Vehicle Routing Problem, algorithms are developed based on travel distance or travel time estimated from an assumed constant travel speed. However, in city logistics, due to a growing amount of traffic and a limited capacity of the road network, travel speed between two locations no longer remains a constant but location and time dependent. In this paper, we propose a framework to visualize...
To build a properly planned infrastructure for plug-in electric vehicle (PEV), charging will bolster their market acceptance. Different types of PEV charging facilities for private PEVs, including public charging spots deployed in public parking lots (PLCSs) and roadside fast-charging stations (FCSs), are substitutes for each other. This paper proposes an integrated planning framework for them in...
Multi-modal transportation planning refers to traffic analysis that considers various modes of transportation mechanisms such as walking, cycling, motorcycles, private passenger vehicles, delivery cargo vehicles, public transportation modes like buses or trains, etc. Effective city traffic planning has become a challenging task involving complex behavioral analysis of multi-modal traffic scenarios...
The Cybernetic Transportation Systems (CTS) is an urban mobility concept based on two ideas: the car sharing and the automation of dedicated systems with door-todoor capabilities. In the last decade, many European projects have been developed in this context, where some of the most important are: Cybercars, Cybercars2, CyberMove, CyberC3 and CityMobil. Different companies have developed a first fleet...
Construction simulation and traffic simulation are complementary to successful planning of microtunneling and pipe-jacking operations in urban areas. With increasing concerns on sustainable development, it is imperative to integrate construction engineering and traffic engineering in simulation modeling in order to plan for efficient site operations while reducing the impact of construction upon traffic...
Based on the statistical and analysis of transfer stations in Xuzhou urban area to determine the quantity and scale of large scale waste transfer station. Form qualitative conditions by the analysis of location factors to determine the weight of each factor to form a quantitative index, trying to use planning methods to narrow the scope of available site area. Ultimately, determine the best position...
With the development of integration of urban and rural public transit, urban bus transportation is playing an increasing role in urban economy. To plan the public transit network at the preliminary stage is of great significance to stimulate urban regional economy and improve the urbanization level. In this article, how to use TransCAD to collect and establish urban public transit network data is...
