Routing of data in a vehicular ad hoc network is challenging task due to the high dynamics such network. Recently, it was shown for case highway traffic that position-based routing approaches can very well deal with mobility nodes. However, baseline has difficulties handle two-dimensional scenarios obstacles (buildings) and voids as city scenarios. In this paper we analyze approach makes use navigational systems vehicles. By means simulation compare non-position-based strategies (dynamic...
This paper proposes an improved cellular automaton traffic flow model based on the brake light model, taking into account that desired time gap of vehicles is larger than one second. Although hypothetical steady state in deterministic limit corresponds to a unique relationship between speeds and gaps proposed states dynamically span two-dimensional region plane speed versus gap, due various randomizations. We show our reproduces (i) free flow, synchronized wide moving jams, as well...
Recent scholars have developed a number of stochastic car-following models that successfully captured driver behavior uncertainties and reproduced traffic oscillation propagation. Whereas elegant frequency domain analytical methods are available for stability analysis classic deterministic linear models, there lacks an method quantifying the performance their peer theoretically proving features observed in real world. To fill this methodological gap, study proposes novel measures magnitudes...
Abstract. Given the increasing complexity of chemical composition PM2.5, identifying and quantitatively assessing contributions pollution sources has played an important role in formulating policies to control particle pollution. This study provides a comprehensive assessment between PM2.5 characteristics, sources, health risks based on sampling data conducted over 1 year (March 2018 February 2019) Nanjing. Results show that exhibits distinct variation across different seasons, which is...
Mobility as a Service (MaaS) integrates various modes of transportation, provides personalized travel services for travelers, and improves the efficiency traditional modes. To examine mechanisms underlying impact sudden public health events on behavioral intentions to use MaaS provide theoretical support sustainable development MaaS, this research investigates Beijing program case. A total 630 questionnaires were collected. Theoretical model, sourced from Unified Theory Acceptance Use...
Reducing forwarding state overhead of multicast routing protocols is an important issue towards a scalable global solution. We propose new approach, dynamic tunnel multicast, which utilizes dynamically established tunnels on unbranched links distribution tree to eliminate unnecessary states. Analysis and simulation results show promising reduction in the sparse mode protocols.
In this paper, a new lattice hydrodynamic model based on Nagatani's [Nagatani T 1998 Physica A 261 599] is presented by introducing the flow difference effect. The stability condition for obtained using linear theory. result shows that considering effect leads to stabilization of system compared with original model. jamming transitions among freely moving phase, coexisting and uniform congested phase are studied nonlinear analysis. modified KdV equation near critical point derived describe...
Cooperative Vehicle Infrastructure System (CVIS) is one of the most valued technologies in intelligent transportation system. By use roadside sensing, it provides extended coverage and more dimensions traffic information compared with independent perception by vehicle sensors. Sensing fusion camera radar can overcome shortcomings both sensors so that trend sensing CVIS. In this paper, we propose a novel It filters out background objects from detection to avoid wrong calibration detection,...
