In this paper, a modified k-nearest neighbor (k-NN) method integrating the cluster analysis and principal component analysis is applied to bus arrival time (BAT) prediction using historical bus GPS data. The methodology of the k-NN method based on processed GPS data is presented. To validate the introduced k-NN approach, empirical analysis based on data collected from the bus No. 16 of Beijing public...
This paper proposes a reliability-admissible filtering mechanism to generate the reasonable route set for the traditional SUE model. This mechanism still takes into account traveler's cost-susceptivity, which is able to dispel the impact of dimension on the traffic assignment. The filtering formula is presented and further estimated based on the Gumbel distribution assumption for the route disutility...
To guarantee the safety of public transport and effectiveness in dispatching buses, overall solution on Beijing bus monitoring system (BJ-BMS) based on GPS is put forward in this paper. The system is composed of communication control and GIS subsystems, each of which was independently developed in the beginning and integrated in the end. The key technologies of the system are described in detail....
By collecting and disposing the correlative information of regional logistics, regional modern logistics common information platform system provides the information systems of production distribution and logistics enterprises for basic information of logistics. At the same time, by sharing of logistics information, it supports the establishment of cooperative mechanism of industry management and market...
Bus route evaluation (BRE) of the public transit system in Beijing is requisite decision to regulate existing bus routes and reallocate transit resources for sustain operation. Since there wasn't a systematic BRE system for Beijing, firstly, this paper develops comprehensive BRE standards according to the status quo of Beijing's transit system, which includes 3 categories, 20 criterions in total....
