With the advances in traffic sensor technology, more useful traffic information can be generated. This paper introduces an innovative single loop speed estimation model using recent traffic sensor technology. Proposed speed estimation model can be easily integrated with existing loop systems without requiring any roadside construction. With accurately estimated speed, accurate travel time can also be derived. This will help disseminate accurate real-time traffic information, and therefore improve network performance, and traffic control/operation. The spatial and temporal transferability tests of the developed model showed encouraging results. Automated vehicle grouping is also one of the main contributions of the proposed model.

The City of Houston flextime initiative was led by Mayor Bill White in 2006 to encourage large employers to implement a flextime program to shift the peak hour traffic characteristics in the city. The City of Houston formed a committee to measure the mobility benefits in terms of travel time savings. The committee was composed of volunteers from the Greater Houston Partnership, the City of Houston, the Texas Department of transportation, and the Texas transportation Institute. The initiative started with two pilot programs to measure the change in traffic patterns at the city street level, and a city-wide program to measure the change in traffic patterns at the freeway level. The two site studies were conducted for Duke Energy in the Houston Galleria area, and for the Johnson Space Center/NASA in the Gulf of Mexico bay area. The freeway program was conducted on all of the Houston freeways using the travel time data collected by TranStar, Houston's traffic management center. The analysis methodology consisted in conducting "before" and "after" travel time studies to measure the change in travel time with statistical confidence. The results were positive and a change in travel time was detected in all cases, making this an effective strategy to manage congestion. A follow-up study at the freeway was conducted in 2007, which also showed positive results. This paper documents the analysis and results of the two pilot projects, Duke Energy and JSC/NASA, and one the freeways, IH 45 (North Freeway).

The EXPO is coming. The key for a successful exhibition is good exhibits Another vital factor is good management of the people flow and logistics. We want to build a perfect managing system to deal with these "flows". First, we must have their information and give them label- RFID tag, a non-contact electronic label that contains unique identify information, can identify many once, and store some custom information. More efficiency will be raised when the RFID tag is used. However, people flow is not like logistics. It has its own initiative, while it offers its information to the system it wants to get the information it wants. RFID has no way to deposit a large quantity of information. It has to rely on other way 2-D technology which can combine 2-D code and the server of network. People can get large quantity of information through 2-D picture, people get and read the information. At present, we can get the 2-D picture obtained through the picture made by our mobile phone. Thus it will be more convenient when the system is built. It will certainly raise the efficiency of managing the people flow and the logistics of the EXPO when RFID is combined with 2-D technology. © ASCE.

Incremental traffic pressure has developed in the large and medium-sized cities of China. A powerful and intelligent transportation system, which is of small start-up funding and convenient structure, will help to ease the traffic pressure and improve the quality of urban traffic. With the technology based on 802.11p standard, it is available to transmit data for 1,000 meters at a maximum rate of 54bps. An on-board wireless communications system based on the technology will be able to collect roadside infrastructure information (such as road information) and send them to the terminal of a vehicle which is moving at high speed. The system also can transmit information (such as the vehicle information, location information of accident cars, etc.) between on-board terminals, so that it can implement the functions of pre-safety and pre-information which are necessary to modern traffic. Then combining with the existing GPRS/CDMA systems and GPS effectively, it is feasible to construct a intelligent transportation system, which is of fewer start-up costs, high reliability and real time capability. Because the major functional modules of the system are equipped on the terminal, an intelligent transportation system could be constituted with just a little road infrastructure and a car which is of the system's on-board terminal. © ASCE.

Programming and arrangement of regional logistics system were studied by fuzzy C-means clustering. The uncertain and fuzzy features for clients to select logistics centers and exchange amount were analyzed by system analysis method. The synthetic evaluation indices were established. The problem of clients' selecting is equal to that of determining the membership values. Then we got the uncertain nonlinear programming model of logistics system. The number of logistics centers or the optimal c value was determined by using the defined rules function. The detailed selecting site and the optimal scale of every logistics centers can be determined by me total scale decomposability, the membership matrix and clustering centers. The theory and method were applied in the logistics system programming of Langfang City in China. The concrete simulation result shows its correctness and feasibility. Copyright ASCE 2007.

The Texas Department of transportation (TxDOT) sponsored research to develop a decision support tool to aid in evaluating key issues related to adapting a high-occupancy vehicle (HOV) lane to a high-occupancy toll (HOT) lane. The tool includes three broad categories of factors to consider: facility considerations, performance considerations, and institutional considerations. Facility considerations, such as design, operations, and enforcement, which have been shown to be critical factors, can present insurmountable obstacles to the implementation of HOT lanes. Performance considerations and goals allow the user to estimate the likely levels of usage and person movement, factors that always bear significantly on HOT lane development decisions. Institutional considerations are also addressed, as factors of interagency cooperation and legal limitations are historically important for HOV lane and HOT lane decisions. Finally, the research incorporates simple trade-off tools to allow TxDOT and local entities to assemble all relevant factors into an analysis to aid decision makers in evaluating the available options. The analysis tool was developed in Visual ***. The program is called the High-Occupancy Toll STrategic Analysis Rating Tool (HOT START), and it is designed to be tailored easily to local needs. An application of the tool to the I-10 (Katy Freeway) in Houston is also provided. Many state departments of transportation are facing the difficult task of performing assessments of potentially adapting HOV lanes to HOT lanes, and this paper describes a practical tool that can assist such analysis.

A uniform circular vertical contact stress is commonly assumed in representing wheel loads in pavement analysis procedures. However, experimental measurements have shown that actual loading conditions are nonuniform and depend on tire construction, tire load, and tire inflation pressure. Predicted pavement response from three-dimensional (3D) finite element (FE) and layered elastic programs were compared to establish guidelines for modeling wheel loads in current layered elastic pavement analysis programs to provide a better approximation of pavement response parameters for design and evaluation. Tire contact pressure was measured with the stress-in-motion pad. In addition, tire contact pressure measurements from a previous study conducted at the University of California at Berkeley were obtained. Available contact pressure measurements on four tires were used to predict pavement response with a 3D FE program, which permitted input of measured tire contact pressures at various tire loads and tire inflation pressures. Horizontal strain at the bottom of the asphalt layer, compressive strain at the top of the subgrade, and principal stresses at different depths were predicted. Similar predictions were generated with layered elastic theory with two different representations of contact pressure and contact area. From predicted strains, service life for a range of pavements, tire load, and tire inflation pressures were estimated with limiting strain criteria. In addition, Mohr-Coulomb (MC) yield function values were calculated from predicted principal stresses at different depths. The MC yield function values and pavement life estimates from 3D FE and layered elastic analyses were compared with established guidelines for modeling wheel loads using existing layered elastic procedures.

Although there is an increasing demand for travel time prediction methods, the efforts put on urban streets are until now less than on freeways. In this paper, a macroscopic model of urban link travel time prediction is developed based on measurements collected by single loop detectors. This method divides travel times into two components: link cruising times and intersection delays. For each component the mean prediction and prediction interval were investigated in order to provide a reliable prediction. Prediction intervals around the mean prediction show the plausible range of travel times a vehicle is likely to encounter. Based on simulation data, it is demonstrated that urban link travel time prediction can be executed by this promising method. © 2005 IEEE.
