	Abstract:In this pape, in order to enhance the accuracy of highway alignment safety evaluation, the crash comprehensive probability was formulated based on fault tree theory, taking sideslip/steering instability, rollover and rear-end crash into account.The driver-vehicle-road multi-body dynamics model was developed based on the three-dimensional alignments of Ning-Luo expressway using Carsim. Each section of the average crash probability were obtained after simulation and calculation, and compared with various sections of the average number of accidents.Results reveal that that at the confidence level of 0.01, when dividing the expressway into sections with lengths of 5km and 10km, respectively, the Spearman correlation coefficients between average crash probability and average number of accidents are 0.636 and 0.460. While the Spearman correlation coefficients using traditional fault tree are only 0.531 and 0.378.

	Abstract:In intersection signal timing, pedestrian phase is quite often treated as a "slave" of the vehicle phase, resulting in unnecessary delays and safety problems. It is highly required to accommodate pedestrians in the signal system, and the development of automated pedestrian detection makes it be applicable. A rule-based dynamic pedestrian control (DPC) strategy accommodating pedestrian in intersection signal system has been proposed in the study. Phase structure including 8 vehicle phases and 4 pedestrian phases for a four-leg intersection has been introduced, and a set of rules regulating phase combination, phase sequence, and phase transition (internal and external) has been established. Dynamic pedestrian clearance interval has also been proposed. Different from previous control strategies, pedestrian demand is a decisive factor for signal timing optimization with consideration of pedestrian safety and comfort. According to simulation results, DPC is beneficial to reduce traffic delay at intersections crossed by a major street and a minor street.

	Abstract:Researches on pedestrian-bridge interaction are not enough. In this paper, the pedestrian-induced lateral forces on a bridge are modelled as a sum of an equivalent static force exerted by pedestrians on rigid surface and a self-excited force due to an interaction between the pedestrian and the vibrating bridge. The dynamic balance equation is first established for the pedestrian-bridge interaction system. And then a new explicit integration method is applied to solve the equation with an iteration algorithm, computation procedures based on MATLAB are introduced simultaneously. In the case study at last, it is demonstrated that the new explicit integration method is absolutely reliable and there is nearly no difference between interaction and no interaction simulation in low crowd density, but big difference in high crowd denstiy.

	Abstract:For the purpose of obtaining the characteristic parameters of the asphalt mixture aggregate particles, the collected aggregate images were processed and a feasible method of characteristic parameters acquisition was put forward. The automatic detection system was developed based on VC++. A series of processing are done on the collected aggregate images, including image edge detection, image segmentation, morphological processing, region-labeling, contouring and so on. The region-labeling algorithm is improved as well. Database technology is used to deal with the storage, query of the results and several other operations. The whole system is characterized with perfect function, user-friendly interface and stable performance, which provides a practical and accurate method for the characteristic detection of asphalt mixture aggregate particles.

	Abstract:This paper aims to find a fast testing method for the asphalt mixture by using the digital image processing method. For the composition of the asphalt mixture contains the asphalt content and the mineral aggregate gradation, the color comparing method is provided to test the asphalt content and the particle analysis method is provided to analyse the mineral aggregate gradation. The normalized histogram of the asphalt mortar part in the asphalt mixture image is compared with that of the asphalt mortar image with known filler bitumen ratio in the colour comparing method to decide the filler bitumen ratio of the asphalt mixture tested. During the mineral aggregate gradation test by using the image processing, the stand image with known gradation is analysed and the average passing rate of each sieve is calculated by using the particle analysis parameters. Then, the correction parameter of each sieve is obtained. In the following test of core sample drilled form the asphalt pavement constructed with the same batch asphalt mixture, the same methods are used consequently to obtain the passing rate of each sieve. The passing rate obtained by the image processing and the correction parameter of each sieve are combined correspondingly to get the final passing rate. The analysis of the asphalt content result show that the asphalt content can be decided accurately if the asphalt mortar image database is rich enough. And the passing rate error of each sieve obtained by using the image processing method is smaller the 2%, which is acceptable. The image-based test of the asphalt mixture composition is worthy practicing in the pavement engineering.

	Transportation Engineering 07 October 2014
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In a transportation system, OD pairs are usually accumulated by large quantities of primary records. The records may come from train tickets, freight invoices, and flight trip tickets etc. In 2013, 2.075 billion passengers are transported by China railway. Each train ticket contains information of origin and destination stations, train number, and train class etc. Only several fields of information, such as origin and destination, are required according to specific research purposes. The rest of the fields are unnecessary and need to be merged. A direct merging method in which each record compares with all existing OD pairs will consume a lot of time when there are large quantities of records. This work will propose a sorting-based merging method, which applies to general OD matrices. The time complexity is scale of O(NlogN) . For tests, 30 samples are used for numerical analyses. The results show that the efficiency is far better than that of the direct merging method.

	7. An approach to merging railway ticket records into origin-destination pairs based on sparse matrix characteristic

	Abstract:This work describes a data merging method under the background of railway tickets data integration. Origin-destination (OD) pairs are fundamental data in transportation engineering, and are widely used in various applications. For example, predictive OD pairs of the long-term future are the basis of optimizing transportation network design. Optimization of transportation plans also relies on existing OD pairs. The size of an OD matrix is always huge in a real transportation system. Each element of the matrix, i.e. an OD pair, is accumulated by numerous passenger tickets or freight invoices. The size of an OD matrix is huge in real transportation systems. In a railway system, each element of the matrix, i.e. an OD pair, is accumulated by numerous passenger ticket or freight invoices. In 2013, China railway system transported 2.075 billion passengers. In other words, an equivalent number of tickets were sold. Each ticket consists of information on the name of origin and destination, train number, and seat class etc. Similarly, a railway freight invoice consists of information on the name of origin and destination, freight category (e.g. coal, oil, grain, and ore), and volume etc. Obviously, the tickets usually contain some identical fields of information. For example, two tickets can share the same origin and destination. Researchers use only particular fields of the tickets for different analysis purposes. Consequently, an effective approach is needed to merge the ticket records based on interested keywords and creates the corresponding compressed OD matrix. A simple direct merging method costs a lot of computations. This work proposes an effective and efficient approach, named origin-associated merging, to merge ticket records based on the sparse matrix characteristic. For experiments, 30 samples are created according to the characteristic of China railway passenger flow, ranging from 200 thousands to 6 million records with a step of 200 thousands records. The experimental results show that the time using origin-associated merging is about 1% of that of direct merging. It is worth mentioning that the number of passenger tickets in China railway system is approximately 6 million per day.

	Abstract:The application of semi-rigid base asphalt pavement structures has complemented the flexible pavement structures. The field test results from a test track built in Chongqing, China proved that, other than material selection, structural arrange can influence the shear rutting level. This paper introduces a simple multiaxial yield equation for asphalt pavement materials. It is closely associated with Mohr-Coulomb theory. It also considers both the strength difference between tensile and compressive loading and the difference between σ2 and σ3 in the actual stress field of pavement structures. An asphalt pavement permanent deformation estimation approach has also been introduced based on the proposed yield criterion. The proposed methods have been verified through the successful application in explaining the field test results of Chongqing test track.

	Transportation Engineering 19 February 2014
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, a new ramp metering strategy is proposed. It restricts the entrance of on-ramp vehicle by space gap. The vehicle from on-ramp can enter into the main road only when the space gap on the main road is large enough. The effectiveness of the new strategy is verified by cellular automata traffic simulation model. The simulation results show that the saturated flux of the main road will be high and not drop by introducing large entrance gap restriction value. The ramp metering strategy with entrance gap restriction is effective.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Updating the structural model of complex structures is time consuming due to the large size of the finite element model (FEM). Using conventional methods for these cases is computationally expensive or even impossible. A two-level method, which combined the Kriging predictor and the component mode synthesis (CMS) technique,was proposed to ensure the successful implementing of FEM updating of large-scale structures. In the first level, the CMS was applied to build a reasonable condensedFEM of complex structures. In the second level, theKriging predictor that was deemed as a surrogate FEM in structural dynamicswas generated based on the condensed FEM. Finally, the effectiveness of the proposed method was demonstrated by updating the FEM of a real arch bridge with the measured modal parameters.
