ABSTRACT Real-time estimation of dynamical phenomena involving large number of agents is critical for Smarter Cities applications. However, for systems with many degrees of freedom, including crowds, the availability of timely structured and usable data remains a …
Abstract Local density, which is an indicator for comfortable moving of a pedestrian, is rarely considered in traditional force based and heuristics based pedestrian flow models.
However, comfortable moving is surely a demand of pedestrian in normal situations…
Abstract Quantifying the systemic risk and fragility of financial systems is of vital importance in analyzing market efficiency, deciding on portfolio allocation, and containing financial contagions. At a high level, financial systems may be represented as weighted graphs that …
Abstract: Urban density must be considered a key concept in the description of a city’s urban spatial structure. Countless studies have provided evidence of a close relationship between built density and activity densities, on the one hand, and urban environmental conditions …
Abstract The intersection model consisting of vehicle model, pedestrian model, pedestrian vehicle interaction model and intersection rules has been presented in this paper. The well established vehicle and pedestrian movement models in the literature are combined and …
Аннотация: В случае моделирования автомобильного трафика в масштабах крупных городов количество транспортных средств может достигать десятков тысяч, что для микроскопического подхода соответствует решению систем обыкновенных …
ABSTRACT We test whether “detrended fluctuation analysis” (DFA) — an econophysics method — identifies the transition from efficient-market trading to herding behavior and the rise of the NASDAQ dot.com stock market bubble. DFA divides a time series into …
Abstract: Many complex systems display fluctuations between alternative states in
correspondence to tipping points. These critical shifts are usually associated with generic empirical phenomena such as strengthening correlations between entities composing the …
Abstract Developments in Intelligent Transportation Systems (ITS), navigation devices and traffic sensors make it possible for traffic participants to not just access real time information regarding the traffic situation but, at the same time, also provide data back to the …
It is assumed that car-following behaviour is the same in different lanes of traffic flow, but it is necessary to investigate whether car-following behaviour in all lanes, in congested and noncongested conditions, is the same or not. For this purpose, the traffic data for a freeway in …
