This tutorial paper examines the operational and economic aspects of autonomous mobility-on-demand (AMoD) systems, a rapidly emerging mode of personal transportation wherein robotic, self-driving vehicles transport customers in a given environment. We address AMoD systems along three dimensions: (1) modeling - analytical models capable of capturing the salient dynamic and stochastic features of customer...
Although various smart city projects are launched in all over the world, it is not obvious how to tailor the existing IoT and self-aware technologies for individual services, systematically. One of the reason is due to the lack of common view that can be used to investigate various smart city services across different domains. This paper proposes a domain-neutral execution model and an integrated...
The environment problem has aroused people's concern in recent years since the heavy haze weather. Agricultural products logistics, acting as one of the necessary activities to keep people's daily life and the main source of environmental pollution, receives widespread attention in the whole society. Basing on the field survey of agricultural products distribution system in Beijing, we clarify the...
In view of the current traffic network of deficiencies in the path selection research, i.e. only consider static traffic network path selection problem. This paper proposed shortest path algorithm under congestion traffic network which is based on ant colony algorithm and builds the traffic network model based on Petri nets, and use ant colony optimization to find the shortest path for the static...
With the life style changing, the distribution has become an indispensable part of people. However, the contradiction between the city-distribution's timeliness and the city traffic's capacity as well as the environment stress makes the last one kilometer distribution become a hot topic. On this issue, Based on the mechanism of the resource store, management and feedback, the authors find the city...
There are several kinds of envisioned vehicular applications: video delivery, accidents detection, dissemination of traffic announcements, and so forth. Such applications demand minimal (and possibly distinct) QoS guarantees that must couple the vehicular network. Given that vehicular networks will soon become reality, we demand strategies for planning and managing such networks. In this work we propose...
Traffic jams frustrate drivers and cost billions per year in time and fuel consumption. In order to avoid such problems, this paper presents an intelligent transportation system that collects real-time traffic information and is able to detect and manage traffic congestion based on this information. Simulation results show that the proposed protocol can reduce the average travel time, CO2 emission...
The rail transit is one kind of urban track traffic systems. The paper focused on the new built rail transit system, Rail Transit Line 1, in Zhuhai, China. The following three kinds of benefits are analyzed. First, the economic benefits, which include the passenger time-saving benefit and the land value-added benefit, have been studied. Second, the social benefits, which have been analyzed according...
The next generation mobile networks (NGMN) are over-taxed by the increasing demand of on-the-go content access. Standards bodies and researchers are building solutions that offload the traffic demands from the NGMN infrastructure to small cells. We motivate a taxicab cloud as a mobile ISP that offloads traffic demands from NGMN to under-utilized licensed bands such as TV whitespaces. This cloud consists...
The Unmanned Aerial System (UAS) market once belonged to professional companies only. Now many amateur pilots fly cheap, smartphone controlled models available in any electronic store. Due to altitude, speed, and weight, these flying objects can cause damage and injury. Hence, a way to manage them is necessary. This paper presents a UAS Traffic Management (UTM) system comprising three components:...
The development of the transport system in cities requires very high investment costs and well-verified assumptions of transportation policy. The undertaken decision will affect the effectiveness of the whole transport system and of travel behaviour of inhabitants. This paper contains easy procedures suggested to verify the effectiveness of transport investment through an ex ante and ex post of the...
With current on-board GPS devices a lot of data is being collected while operating taxis. This paper focuses on analysing travel behaviour and vehicle supply of the Berlin taxi market using floating car data (FCD) for one week each in 2013 and 2014. The data suggests that there is generally a demand peak on workday mornings and a second peak over a longer time in the afternoon. On weekends, the demand...
This paper introduces a simulation environment developed for analyzing crowd-sensing based applications in the Smart City application domain. As a case study, an urban parking application scenario is investigated and presented. In this scenario, smart citizens collect and share parking related events, such as leaving or occupying a free parking spot. These events can be presented on a real-time city...
This paper discusses a case study evaluating the potential impact of ITS traffic management on CO2 and Black carbon tailpipe emissions. Results are based on extensive microsimulations performed using a calibrated VISSIM model in combination with the AIRE model for calculating the tailpipe emissions from simulated vehicle trajectories. The ITS traffic management options hereby consist of easily implementable...
Advanced Traveler Information Systems (ATIS) are commonly used nowadays in order to provide various benefits to travelers. Their range of benefits range from more informed travelers on real-time traffic conditions of an area's road network to fuel savings and reduction of emissions. However their effectiveness is strongly rely on their acceptance by the users and the following reaction of the users...
In Iran, shared taxis are playing significant role in public transport. Maneuver of shared taxi through lanes in order to pick-up and drop-off passengers and asking their destinations may lead to disorder in traffic flow. In order to investigate the effect of these maneuvers (or sudden lane changing) on traffic flow, it is essential to simulate these maneuvers on the existing roads in intelligent...
The article outlines chosen technical possibilities in the field of metropolitan transportation organization based on justified modal splits. The introduction clarifies the policy of sustainable transport and ways of determining modal splits. The article also summarizes existing obstacles linked with the organization of modal splits within the transportation network. It also outlines modern, developing...
In the steep uphill area of a tunnel in the city highway, because of the brightness environment coupled with gravity causes the drivers slowing down the speed unwarily. This will makes the average speed of vehicles reduce. Based on METANET model shows that this section can be equivalent to reducing lane bottleneck road, with traffic flow increases, the degree of congestion has catastrophe. The simulation...
Energy used to overcome elevation is a significant factor in estimating energy consumption of moving objects and (electric) vehicles in particular. A common source of elevation data for electric vehicle energy estimations are digital elevation models (DEMs). These DEMs are available from multiple providers and with varying quality as free or paid data. This paper presents an evaluation of the impacts...
In this study, using the network approach, we analyzed the urban public transportation systems of 5 Hungarian cities. We performed a comprehensive network analysis of the systems with the main goal of identifying significant similarities and differences of the transportation networks of these cities. Although previous studies often investigated unweighted networks, one novelty of our study is to consider...
