A discrete event system simulation model for cruising taxis is proposed. The dynamic processes of taxis searching for passengers and providing travel services are simulated. The impacts of search strategies and radio dispatch system are studied. Through a simulation experiment, it is shown that strategies based on history information can help to raise system efficiency, and cruising taxis can not...
Ridesharing is attracting more and more attention due to its high potential for applying new business models to private transportation in urban areas, reducing the greenhouse gas emissions and decreasing the amount of traffic on the streets. The paper extends the earlier presented approaches of building sustainable logistics system that support ridesharing by applying to it principles of smart spaces,...
Simulation model has been proven an effective tool for analyzing complex vehicle movements under sophisticate transportation environment, including the container operations in the freight terminals. In order to replicate the consecutive activities that each truck has to go through to fulfill its task in the freight terminal, system modeling of terminal operations can provide a seamless analysis to...
Transportation is an important contributor to environmental problems like declining air quality. Current traffic measures seek to optimize travel times, but fall short on the ideal of an ecologically friendly traffic system. The European research project eCoMove aims to reduce the overall fuel consumption in traffic by 20 percent by means of energy efficient driving behavior and energy efficient traffic...
This paper presents three types of learning behaviors with complete information, partial information and no information respectively, and thus models travelers' route choice for investigating the impact of memory on the evolution of transportation system. Simulation results on a three-parallel-route network show that it is uncertain whether the information released by advanced traveler information...
A discrete event simulation model for cruising taxis is proposed and the impacts of the search strategies on system performance are quantitatively analyzed. It is shown that search strategies based on history information can help to raise system efficiency. These are helpful to taxi drivers and supervisors for providing better service.
Motor vehicles consume a big share of the world's oil supply. They are, also, the major source of pollution to the surroundings. Efficient designs, alternative fuels and rational transportation systems can help solve the problem. In Libya, the rapid increase in the use of the private vehicles has resulted in increased traffic congestion, accidents, inadequate parking space and air pollution, among...
This paper explains the phenomenon that taxi drivers of all over the country on strike with bounded rationality model, and draws several conclusions. First of all, Parties' limited cognition leads to contracts are incomplete, which will require renegotiation. The main reason of the strike is that taxi drivers own little power on the renegotiation but not the increased rent, unauthorized taxi and so...
This paper proposed a novel model to evaluate the service level of public transit in peak hour. The evaluation index are selected by using analytic hierarchy process, which includes travel time reliability, punctual arrival reliability, capacity reliability, driving skills of drivers, crowing level of vehicle, vehicle environment, and economical ticket price. The quantitative value of satisfaction...
Variable message signs (VMS), also known as changeable message signs (CMS) or dynamic message signs (DMS), are traffic control devices to communicate with motorists. A VMS is generally used to inform motorists the roadway, traffic, or weather conditions. It is also used to display travel times and public service announcements. This study attempts to utilize archived traffic data from the MRR1 freeway...
Transport systems play critical role in modern day economies and are prime example of highly dynamic complex systems. Current traffic monitoring systems do not provide timely and granular information which could sufficiently meet system analysis requirements. Simulation augmented with virtual reality (VR) has emerged as an important methodology to model and analyze transport systems. This paper-reports...
A novel user equilibrium traffic assignment model in view of the drivers' different familiar levels with the network is presented in this paper. In the model, drivers are divided into classes according as their knowledge about the network traffic condition and travel-decision characteristics are the same within each class, but differ among classes. Some new concepts, such as OD perceived cost and...
This paper discusses the manner in which cinema buildings of the 20th century represent both an important physical record of society, and a challenge in terms of representing a complex range of historical, cultural, economic and physical data sets.The paper provides an overview of visualisation techniques which are appropriate to the subject, and provides a case study taken from the city of Aberdeen...
