The advances in sensor technologies enable real-time collection of high-fidelity spatiotemporal data on transportation networks of major cities. We consider a set of speed sensors that are spatially distributed along a street and can communicate via an exogenously determined network. In this paper, we address the problem of detecting in real-time collisions that occur within a certain distance from...
Journey planning is the key to an efficient andsustainable transportation system in a smart city. A good journeyplanner is expected to help commuters travel safely, comfortablyand quickly, as well as keep the whole transportation networkrunning efficiently. In modern cities, it should be able to combinea wide range of private and public transport modes, and moreimportantly, react to real-time events...
We analyze the work of urban trip planners and the relevance of trips they recommend upon user queries. We propose to improve the planner recommendations by learning from choices made by travelers who use the transportation network on the daily basis. We analyze a large collection of individual travelers' trips collected from the automated fare collection systems; we convert the trips into pair-wise...
Most large cities suffer with congestion problem, one of the main causes of congestion is the sudden increase of vehicle traffic during peak hours, mainly in areas with bottlenecks. Current solutions in the literature are based on perceiving road traffic conditions and re-routing vehicles to avoid the congested area. However, they do not consider the impact of thesechanges on near future traffic patterns...
The goal of our project is to explore the already installed video surveillance cameras in the cities to provide an intelligent vision based approach for vacant parking lots detection and drivers' guidance. Our system should be able to treat huge number of parking stations in the town and to supply a real time information about the vacancies and their locations. The concept of distributed and extensible...
In developing countries like India, limited Intelligent Transportation Systems (ITS) infrastructure is available and it is difficult to generate real time traffic information for city wide or larger regions. On the other hand, cellular network is widely deployed in India covering major part of the road network. However, cellular network based positioning data have large location error (250-500 meters)...
Traditional methods of detecting fake plates are mostly inefficient. They usually require lots of investments in advance. These methods cannot fully play potentials of ANPR (Automatic Number Plate Recognition) data and utilize them to detect fake plates quickly. In this paper, we propose a method, called as FP-Detector, to instantly detect fake plates through parallel analyzing the historical large-scale...
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...
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...
Transportation is the backbone for any economy. As the number of vehicles is increasing day by day, traffic jams or congestions are very common. Jams are not only frustrating, but also increases air pollution. It has adverse effect not just for our climate, but everybody's health too. Most ITS techniques are not capable to solve the problem of traffic congestions in developing regions due to high...
The traffic congestion which is a recurring problem all over the world. In a country like India, where economy growth is much fast, the problem is seriously felt in all major cities. Along with this, improving conditions of road and increasing vehicles, the variety, the indeterminacy and the complexity of urban road traffic conditions, are even more obvious, it causes the failure in Static Route Guidance...
Road traffic congestion conditions are getting worse day by day, it is due to rapid growth of vehicle volume on roads. Therefore, the road traffic management is a major concern. Vehicles, mostly uses traffic congestion information broadcasted by FM Radio operators. Currently FM Radio operators get this information telephonically from media reporters in India. This information might be insufficient...
Use of public transportation is on a rise, enabling greener cities and improvement of the quality of life of the city residents. The challenge for the public transportation system is that its demands are non linear and the passengers' experience depends on many human factors. UnCrowdTPG is a mobile service and a research platform that has been developed for understanding the mobility patterns of the...
In this paper, we propose a two-layered parking lot management system for charging scheduling of electric vehicles (EVs) considering a realistic vehicular mobility pattern. EVs are categorized in two groups based on their mobility patterns: Regular EVs and Irregular EVs. We use the data from an vehicular mobility trace collected from the Canton of Zurich for the regular EVs and a probabilistic pattern...
With the advent of Smart Cities, public transport authorities are more and more interested in Intelligent Transport System (ITS) applications that allow to process a large amount of static and real time data in order to make public transport smarter. However, deploying such applications in a large scale distributed environment is challenging and requires an automated, scalable, flexible, elastic,...
This work is aimed to describe a cognitive traffic management system (CTMS) based on the Internet of Things approach. Telecommunication technologies, which can be used for the system development and deployment, are analyzed. Smart traffic light integration is proposed as a replacement of the existing traffic lights. The main purpose of such replacement is to optimize traffic management processes which...
This paper presents the difference of the real time driving cycles between Beijing (China) and Karlsruhe (Germany). According to the comparison and analysis of the both drive cycles the influences of the drive cycles on design of an electrical motor for electric vehicles (EV) will be shown in this paper. In this paper a PMSM-EV-In-Wheel-Motor will be proposed as a reference design.
In the last years there has been a significant interest from academia and industry for interfacing vehicles with mobile devices to offer services to drivers. Kinematics information, automotive diagnostics, consumption data can be provided by vehicles to make the roads greener, safer and smarter. In this paper, we define and design an embedded solution to support drivers in driving process. It can...
Energy overconsumption and greenhouse gas emission have been contributing to air pollutions and the global warming for years. The unceasingly increasing number of fossil fuels based vehicles around the world is considered as one of main factors making to the situation worse year by year. Electric vehicles (EV) are promoted as a viable and promising alternative transportation means for customers. However,...
Modern cities continuously struggle with infrastructural problems especially when the population is massively growing. One affected area is public transportation. In default of offering convenient and reliable service the passengers tend to consider other transport alternatives. However, even a relatively simple functional enhancement, such as providing real-time timetable information, requires considerable...
