In this paper, which is part of a complex study of the urban-geographical development of Zadar, the author elaborates the main components of its traffic system. Special attention has been paid to the town traffic and to the importance of Zadar traffic function for its region and for Croatia. The elements of the urban traffic system: streets, roads and town bus lines have been treated in particular. The importance of the transit and regional traffic function of Zadar has been pointed out. There are characteristic indicators of the number of travellers and cargo quantities in the ship, railway, bus and airway traffic. Consideration has been dedicated to the significance and development of the Zadar sea port as well as to necessities of an efficient future development of all traffic functions in conformity with the necessities of town, region and Croatia.

The slow traffic system, which has a series of advantages including low cost of traveling, green environment protection and fewer resource-consuming, indicates its important role in the urban traffic system. This paper, through the research on the slow traffic system and based on current slow traffic system construction, puts forward new urban traffic mode including connection of “BRT (bus rapid transit) and PBFR (public bike free rental), integration of NBT (Normal Bus Transit) and TBB (take bicycle on bus), and planning of SCF (special cycle facilities) and SFW (special foot way) and NBT(normal bus transit).Finally, the paper Prouides a reference for exploring urban green and sustained development.

Operator Behavior

Using the same vehicles for both passenger and freight transport, to increase vehicle occupancy and decrease their number, is an idea that drives transport planners and is also being addressed by manufacturers. This paper proposes a methodology to simulate the behavior of such vehicles within an urban traffic system and evaluate their performance. The aim is to investigate the impacts of resignation from fleet ownership by a transport service company (TSC) operating on a city-wide scale. In the simulation, the service provider hires private autonomous cars for tour performance. Based on assumptions concerning the operation of such vehicles and TSCs, the software Multi-Agent Transport Simulation (MATSim) is extended to model vehicle and operator behavior. The proposed framework is applied to a case study of a parcel delivery service in Berlin serving a synthetic parcel demand. Results suggest that the vehicle miles traveled for freight purposes increase because of additional access and egress trips. Moreover, the number of vehicles en route is higher throughout the day. The lowering of driver costs can reduce the costs of the operator by approximately 74.5%. If the service provider additionally considers the resignation from fleet ownership, it might lower the operation cost by another 10%, not taking into account the costs of system transfer or risks like vehicle non-availability. From an economic perspective, the reduction of the overall number of vehicles in the system seems to be beneficial.

Svm Model

Oversaturation in the modern urban traffic often happens. In order to describe the degree of oversaturation, the indexes of intersection oversaturation degree are put forward include dissipation time, stranded queue, overflow queue and travel speed. On the basis of selected indexes, the genetic algorithm support vector machine (GA-SVM) model was proposed to quantify the degree of oversaturation. In this method the genetic algorithm is used to select the model parameters. The GA-SVM model built is used to quantify the degree of oversaturation. Combining with the volume of intersections in Guangzhou city the method is calculated and simulated through programming. The simulation results show that GA-SVM method is effective and the accuracy of GA-SVM is higher than support vector machine (SVM).This method provides a theoretical basis for the analysis of traffic system under over-saturated traffic conditions.

Traffic Theory

Traditional traffic planning theory cannot satisfy the developing requirements of high efficiency, justice, safety, environmental-friendly and low consumption any more in a future city. The successful experience from domestic and international urban transmit development indicates that the fundamental solution to solving urban traffic problem is developing the Green Traffic with sustainable features. As the only inland national-level opening new area, Liangjiang New Area undertakes a new historic mission. Based on many advanced experience of developing the Green Traffic in some domestic and international cities, this article will explain the Green Traffic Theory in depth through the integration of urban traffic and land utilization, the greening of urban integration traffic system, the greening of traffic environment and the greening of urban traffic management. And also, it will discuss the solutions of developing the Green Traffic Planning and provide some assumptions for the Green Traffic Panning in Liangjing New Area.

Save Energy

Under the situation of rapid development of urban vehicles, worsening traffic congestion and the energy shortage, slow traffic system reflects concept of sustainable development of people-oriented and green environmental protection which is attracting more and more attention and recognition from the citizens. The efficient slow traffic system can not only save energy and alleviate the urban traffic congestion, but also improve the comfort and security of the citizens and guide them to form a new concept of green travel. In recent years, Guangzhou has set up the slow traffic system which based on the development of the Asian Games’ greenway, but on the detail design and user’s experience is questionable. This article will be based on the analysis and summary of the existing domestic and foreign slow system development model and the actual case studies. Then draw lessons from the experience, study the case of Ersha Island and combine with existing design of the greenway in Guangzhou. Use the bottom-up perspective to explore the slow traffic system design in central city of Guangzhou. In the future development, we should optimize for the detailed design in slow traffic system construction as well as the relevant planning and policy, and finally to promote the development of slow traffic system.
