Authors: Bai Lin Feng , Xing Dian , Fu Cheng Long , Zhu Ling Zi , Zhu Ming
Published: September 2013

In the process of conventional traffic control, it often occurs that no vehicles run on a lane when the lane gets a right of way, which lengthens the vehicles waiting time and brings down the guiding efficiency. To get rid of this drawback, this paper proposes a traffic guiding method based on actuated control and phase jump. Time to make a phase jump is decided by the obtained knowledge of queued vehicles. For a light traffic, this paper has deduced the dynamic green time, designed a detector and achieved signal timing by the actuated guiding algorithm; For an almost saturated traffic, the maximum green time and cycle length are restricted by Webster-Monte Carlo Simulation. From the comparison of principles and applications of different guiding strategies, it is found that the method proposed in this paper has a better performance in guiding traffic flow than the existing actuated guiding strategy and the adaptive guiding strategy.

Authors: Zhang Qi , Yi Chen Yang
Published: September 2013

According to characteristics of passenger flow distribution in urban railway network, proportion factors were defined to present statistic characteristics of passenger distribution at stations. An agent-based simulation model was presented to describe interactive effect among passengers, stations and trains. Two series of scenario experiments were designed, considering passenger distribution at stations and trains frequency. Station factor experiments show that increase of transfer passenger proportion of major transfer direction has different effects on passenger numbers at stations with different locations. Train headway experiments show that adjustment of train service frequency in circle line, compared with radial line, has an obvious effect on passenger flow in network. Experiment results in case study prove the validity of the simulation model on reflecting passenger distribution characteristics in urban railway network.

In order to describe the mainline drivers characteristics accurately, the mainline vehicle acceleration, the relative speed of the current mainline vehicle to the all mainline vehicles and the lag gap of the mainline vehicle are selected to cluster by the fuzzy clustering method, and the driver type distribution model is built by K-S test method. Then, the driver type distribution data as a key parameter is incorporated into the expressway merging model, in order to represent the effect of driver characteristic on drive behavior. Finally, the microscopic traffic simulation system MTSS is taken as the simulation plat to build simulation model and validate the built mainline driver type model, the output results from the simulation system are compared with the field data, the satisfactory results indicate that the built driver type model can be used to describe the impact of driver type on driving behavior.

We mainly focus on the three dynamic factors which are cycle length, platoon length and traffic flow continuation. An integrated correlation model is established to quantify the correlation degree of adjacent intersections and then a dynamic partition algorithm is developed based on the model. Both this algorithm and Changs algorithm, which is a representative achievement in subarea partition cited by Traffic control systems Handbook, are applied to a network including 20 signalized intersections in VISSIM to compare their benefits. Statistical results show that: (a) adjacent intersections with high correlation degree can be partitioned into one subarea to execute signal coordination according to our algorithm; (b) implementing our algorithm can save average vehicle delay by 8.9% and average vehicle stops by 7.8% than implementing Changs algorithm.

The results indicate that by carrying out the K-means cluster analysis on the water quality of the longitudinal water strata according to the 3 cluster sets, the cluster centers of the cluster groups where the water strata of the withdrawal intake outlets are that are counted up can predict outflowing water quality of the water tower effectively; the degree of consistency of the predicted temperature, pH, ORP, conductivity, salinity, alkalinity with the actual test data is relatively higher, and the relative errors were within the-10% to 10%. Polynomial curve fitting was done for the upper and lower boundaries of the cluster group where the water strata of the withdrawal intake outlets are, and the outflow concentration obtained conformed to the theoretical derivation and the actual situation.

Authors: Cai Quan De , Luan Wei Xin
Published: September 2013

The micro-layout research of the reclamation area involves many other areas and disciplines, occupies an important position in the coastal economic study. On the base of geometry theory, this paper puts the micro-layout of the reclamation area under the economic analysis within the formation of two-dimensional plane of the grid point topology. Here we take the Heishijiao coastal areas of Dalian as the example for micro layout of the reclamation area research within the two-dimensional plane variable framework, which is calculated by the Ising lattice model. For the better macroeconomic development in the area as the objective function, the maximum economic value will determine the optimal layout. The results show that, in coastal reclamation area it should not be paid too much notation to the width of the extension in the sea, and more reclamation area should be gathered to the city's prosperity zone reflected in the overall layout of layering.

Effect of Limited Water Supply on Crop Growth of Spring Maize (Zea Mays)
Authors: Zhang Heng Jia
Published: September 2013

An experiment was conducted to determine the effect of limited water supply on plant height, leaf area, dry matter and net assimilation rate (NAR) of spring maize. The results indicated that limited water supply had little effect on plant height of maize at six-leaf, twelve-leaf, heading and early grain filling except the end of filling. Leaf growth and leaf area expansion were effectively increased at middle and late maize growth stages under limited water supply and the maximum leaf area was maintained at early grain filling to middle filling. In addition, dry matter accumulation of maize in reproductive organs may be promoted by limited water supply. Finally, limited water supply also had great effect on net assimilation rate of maize and the maximum was maintained at six-leaf to twelve-leaf, followed by heading to silking.
