This research proposes a method to create an objective comfort index for public transportation and suggests the use of low cost technology to acquire the required data. A case study of Montreal showcase the approach for two key indicators: vehicle's vibrations, and noise levels. Cross comparisons to London (U.K.) and Santo Domingo (Dominican Republic) were used to characterize the degree of comfort...
Short-term traffic forecasting has been a hot research area in transportation research for more than sixty years. In recent years, more and more spatio-temporal models for short-term traffic forecasting were put forward with the consideration of spatial-temporal characteristic of traffic. This paper reviews the spatio-temporal models on short-term traffic flow forecasting and points out that the novel...
Since fairness deals with the quality of distributing the jobs and creates an ambience that is free from any discrimination, any distribution management problem must take fairness issue into consideration. Again, since the Vehicle Routing Problem (VRP) is also a distribution management problem, any VRP solving algorithm must consider the fairness when solutions are explored. However, most of the proposed...
The estimation of bus travel time and providing accurate information about bus arrival time to passengers are important to make public transport system more user-friendly and thus enhance its competitiveness among various transportation modes. However, for the system to be effective, the information provided to passengers should be highly reliable. The model and technique used for prediction plays...
As the important part of the comprehensive transportation service system, the intermodal passenger transport can bring the comparative advantage of all sorts of travel transportation into full play and improve the transportation efficiency and service standards. It is an important point of promoting the comprehensive transportation construction. With the surging demand in the economically developed...
This paper builds important evaluation indexes for urban rail transit network. Besides degrees and betweenness in complex network, I add PageRank value and passenger flow indicators in consideration of the urban rail transit network topology model to better evaluate relationships between stations in urban rail transit network and offer theoretical guarantee for risks. We provide factor analysis method...
Manual motion control (MMC) problems are seen in the conveyance of a large amount of products in factories and stores. One of the most successful examples of MMC is power assist. The power-assisted systems have been introduced to reduce workers' loads in industrial production. In near future, in order to improve its efficiency, the power-assisted systems should include automatic operational modes...
Nowadays, the human mobility always happens in a multimodal transportation network. However, the transport system has become more complex. Therefore, building Advanced Travelers Information Systems (ATIS) that provide passengers with pre-trip information on navigating through the network has become a certain need. Since passengers do not only seek a short-time travel but they endeavor to optimize...
This paper studies car trajectory predictions desired in several active safety systems, such as automatic emergency braking (AEB) systems and lane keeping systems (LKS). In the former, the car trajectory is estimated such that objects detected within this trajectory in front of current host vehicle are taken into consideration of collision avoidance. In LKS, the trajectory predictor is utilized to...
The right-of-way conflict such as lane-merging problem between Autonomous Vehicles (AVs) is an inescapable issue. Related studies formalize the problem using centralized decision-making models of “Reservation” or “Auction” from the perspective of intersection management, that are suitable only for the scenarios with a centralized intersection agent; and the fiat currency spent on bidding may trigger...
The seaplane has the dual characters of both the ship and the aircraft, including the heavy load, fast speed of flight and able to fly in the surface of water. Recently, the seaplane has been developed rapidly. But due to the safety management of seaplane involves two department of maritime and aviation, safety management still lacks clear definition, and the research on this topic is at the beginning,...
To provide a basis to quantitate the navigational risk and evaluate the traffic safety for maritime safety administration to control the traffic as soon as possible to assure the traffic safety, this paper referred to the study on conflict delay time of road traffic and the application of traffic conflict technique used in waterway traffic, we try to analyze the influencing factors of navigational...
Anomaly detection in bipartite graph is of great use in many real applications and therefore it attracts numerous research efforts. This work formulates the supervision on abnormal activities in vehicle inspection stations as an anomaly detection problem in weighted bipartite graph. Relevance scores and normality scores are computed for registration districts and inspection stations. The suspicion...
The zero-inflated negative binomial regression model is used to study the influencing factors of casualties in water traffic accidents. The Pearson correlation analysis is used to obtain the influencing factors of casualties in water traffic accidents. The ZINB regression model is established to evaluate the influencing factors. According to the analysis results, influencing factors are sorted in...
With the increasing emphasis on marine environmental protection, marine oil spill prevention and emergency response have become the focus of attention. Dispatch of oil spill resources is an integral part of the marine oil spill emergency response system. Rational selection of resource storage locations and transport routes play a crucial role in providing timely and reliable emergency response to...
This paper establishes the index system of the safety evaluation of navigation environment from perspective of which affects the navigation safety. After that, Bayesian network security evaluation method is introduced and the fuzzy set theory is combined to construct a safety state evaluation model. Then the safety condition of the navigation environment is expressed in the form of safety probability.
