In order to explore the recognition method of distracted driving in operating in-vehicle information system (IVIS), the effectiveness of driving performance indicator as the evaluation variable of distracted driving was verified by using variance analysis method. Experiments under IVIS operation based on driving performance were carried out, and road scene video and driving performance indicators data were obtained. According to the driving performance data under IVIS operation, using support vector machine (SVM) classification algorithm, the driver distraction judging model was built based on vehicle driving performance under IVIS operation, and the effectiveness of the model was validated by experimental data. The results show that SVM model can be used to determine the driver distraction state. When using RBF kernel function, the recognition accuracy of driving distraction is 89. 86%, higher than those by using Sigmoid and polynomial kernel function. The model can effectively determine the driver distraction state, which can provide data support for driving distraction control strategy. © 2016, Editorial Department of China Journal of Highway and Transport.

During the history of Asian Games, the 16th Asian Games is the one which has the largest number of competition events, joining people and competition venues. Traffic demand leaded by the Games will be highly gusty, mass and impactive. Under this condition, the daily traffic of the holding city has already been saturated, the games traffic and daily traffic will compete on the city's transportation resource. In view of Guangzhou city's daily traffic demand and operation situation, the paper systemically analyzes the traffic demand characteristics of Asian Games from aspects of passengers flow scale, service object, request standard and space-time distribution. It also applies two traffic organization strategies to ensure Asian Games traffic to be safe and smooth efficient and ordered; "centralize transportation resource to ensure Asian Games traffic quality of service and reduce transportation disturbance for harmonious Asian Games traffic". It then provides helpful suggestions for city to ensure effective traffic operation in large-scale events.

Distinct from traditional gymnasium-inside patterns, the 16th Asian Games opening ceremony was held on the Pearl River Haixinsha island which is water surrounded, and strong opened central business district. Before the start of the opening ceremony, the parade function was conducted on the Pearl River, whose route cross through the whole central district. Because of the special venues and patterns which have not been used in the history of the Olympic and Asian Games, the traffic organization for this opening ceremony faced a real great challenge. Therefore, the organization mechanisms of flexible planning, hierarchical management, static and dynamic binding, time and space separation were applied and other useful methods of large-scale events are taken. The program design of traffic control, parking layout, public transportation organization, and the traffic flow line of approach-leave gymnasium were well developed and implemented, which successfully solved the traffic organization problem for large-scale events opening ceremony holding in CBD open space. Meanwhile, it provided valuable experiences for the traffic organization of large-scale events in the future. Copyright © 2011 by Science Press.

Current researches on road network vulnerability (RNV) are mostly focused on its evaluation and calibration, while the classification is rarely studied. For there’s no unanimous and standard criterion in researches on the levels of RNV, it is urgent to find a practical method to define RNV classification for better traffic monitoring and management. In this study, a methodology based on fuzzy clustering is constructed to define the RNV categories. At the same time, this study presents a method to calibrate the availability of such classification. A case study using this methodology is implemented in Xingsha District, Changsha City for determining appropriate RNV categories in the year of 2011. It is found that (1) RNV of this district can be classified into three categories: serious vulnerable level, middle vulnerable level and feeble vulnerable level. (2) links in the artery are at serious vulnerable level of RNV (3) most links are at the middle vulnerable level, so the RNV in the district can be generally defined as at middle vulnerable level. © (2014) Trans Tech Publications, Switzerland.

Infrastructure construction mainly including road and rail can temporarily relieve the contradictions between traffic supply and demand. But there is un-sustainability, because capital and time is limit. So the key point of managing traffic congestion is how to allocate limited traffic resources. In this paper, basing on an integrated transport model, a traffic system capacity optimization method is proposed as a breakthrough of the right of way for the bus. This method proposes the definition of transportation system person capacity. It builds the criteria to measure comfort and controllability. It establishes hierarchical bus lane layout method. It dynamically adjusts road resources between bus and car to protect the right of way of ground bus. It balances the travel speed between car and bus. It transforms personal best into system optimization. It is a new path to implement transit priority. In Guangzhou, capacity analysis technique is applied to the actual road network, and resource allocation scheme is proposed based on bus lane scheme. It guides the development of Guangzhou city traffic. Copyright © 2015 by Science Press.

On the basis of a large number of questionnaires, a model is proposed to describe the relationship between passenger gross satisfaction (PGS) and nine properties such as passenger waiting time, walking time, travel conditions and so on by using the Naive Bayes classifier. The model achieves the prediction accuracy of 79.9%. The results show that the relationship between PGS and bus waiting time is nonlinear. If the proportion of bus waiting time, which is less than 5 min (PBWT5), increases by 1 percent, the PGS will increase by 0.07 percent when PBWT5 is less than 33.8%. However, when PBWT5 is over 33.8%, If PBWT5 increases by 1 percent, the PGS will increase by 0.04 percent. © 2016, Science Press. All right reserved.

To scientifically evaluate the impact of motorcycle forbidden policy on resident travel time cost, this paper takes Guangzhou as a case for research. The Guangzhou resident travel characteristics and parameters are analyzed through the traffic survey data of Guangzhou. Then the methods of willing investigation and historical trend analysis are used to determine the inhabitant mode share in two hypothetical cases: wtether the motorcycle forbidden policy is implemented or not. The comparative analysis model is developed considering several factors such as traveling purpose, traveling time, resident income and other factors. The results shows that the motorcycle forbidden policy will increases the overall resident travel time cost by 3. 01%, among which, the cost of restricted groups increases by 53.47%.

There are many uncertain factors affecting the service level of urban road network. The paper discusses the connecting route problem among urban areas. It proposes a robust optimization model taking the description of stochastic time-dependent network and selecting principles for robust paths into consideration. An advanced Dijkstra algorithm is put forward to solve the problem. Using Shenzhen GPS data, the paper establishes a stochastic time-dependent network, and studies the model and algorithm of the optimal robust path. The results indicate that the travel time varies from the different departure time, and the components of path are not the same, neither. At last, the result is compared with ones which are obtained by a normal algorithm based on time-dependent network. The comparison shows that the advanced algorithm is an effective method to apply into selecting robust route among urban areas.

This paper focuses on module structure of traffic mode choice in terms of model framework, basic form of utility function, and parameter calibration and validation, based on resident trip survey in Guangzhou. The basic principle of mode split is proposed, and hierarchical division through non-car family, car family, and motorcycle family. This basic hierarchy partition is illustrated using an example of car family. Next, the method and basic steps of parameter calibration and key points of parameter validation are presented. In the final section, the forecasting results and field data are compared for validation purposes. The use of these household attributes increases the accuracy of the model, while the introduction of income, car ownership, and travel volume characteristics improve the adaptability of the model. The results will provide guidance for structure of traffic mode choice in similar-type cities.
