Case Study of Transportation Planning Based on Land Development Patterns in the Great Chengdu Area

Traffic is a function of land use. Based on the understanding of mutual influences between transportation investment and land development, transportation corridors of various levels in Great Chengdu Area （GCA） were investigated. Trip generation was predicted based on population expansion, and trip attraction was estimated based on land use intensity coefficient. Lane assignment of transportation corridors with case studies is expected with two-way-six-lane routes connecting county-cities, two-way-four-lane routes connecting new towns in plane area, and two-way-two-lane connecting new towns in hilly area and prime villages.

The Study on Protection and Construction Mode of Urban Ecologically Sensitive Areas

The paper had analyzed the necessity and feasibility for the protection and utilization of urban ecologically sensitive areas, proposed planning urban ecologically sensitive areas reasonably and combining ecological protection with development construction. Guiding the healthy and ordered development of urban spaces was the key part and important approach to realize ecological cities. The guiding thought for development construction of ecological cities had been discussed, which was conducting laddered development according to the location and coverage of urban ecologically sensitive areas and protection grades of these sensitive areas. Then, it had proposed four kinds of protection and construction modes, which were tourism leisure green lands, relevant expositions, industrial areas and new city groups, and which had been analyzed by combining with successful cases, so as to provide feasible win-win development strategies of ecology and economy for the planning of urban ecologically sensitive areas in the future.

Land development suitability analysis for transport planning evaluation and optimization in mountainous ecological region

Transportation planning is a critical component for creating an orderly,intensive,and sustainable pattern of land development.By comprehensively considering the potential and suitability of transport construction,a comprehensive method combining resources and environmental carrying capacity(RECC)and land development suitability(LDS)was developed by using techniques of GIS,analytic hierarchy process(AHP)and threedimensional magic cube.Taking Aba prefecture in Sichuan Province of Southwest China as a case study,LDS for transportation was analyzed from three aspects,including overall planning layout,different transport modes,and transportation projects.The results showed that the transport planning scales of most counties in Aba were suitable,and the order of LDS of different transport modes was railway>highway=superhighway>tourism track,which already included 42 new transportation projects.We found that two counties(Maoxian County and Jiuzhaigou County)should improve the ecological protection level of transportation,in which the railway network construction should be encouraged,and some transportation projects with low LDS should be postponed or constructed harmlessly.We suggest the combination of RECC and LDS for transportation could enhance the territorial space optimization and sustainable transport construction.

TRANSPORT PLANNING FOR NEW TOWN DEVELOPMENT:EXPERIENCE OF HONG KONG

Since the 1960s, Hong Kongs new towns have been builton the assumption that they could be socially and economically selfcontained entities. A study of the linkage between three new townsand metropolitan area confirms that substantial commuting trips arestill made. The new towns serve as dormitories for people workingin the metropolitan area. The commuters' reliance on publictransport is significant. The towns are thus far from self-containedeven aller 20 years of development. The public transport network,trip rate, peak factor, purpose, mode choice, costs and journey time,are signilicantly different from those originally estimated. Thesemay be related to distance from the metropolitan area,theavailability of modes, the structure of the public transport netwrk,and changs in the economical structure of Hong Kong. lt suggeststhat the direct and indiscriminant importation of Westernplanning practice to plan new towns with an oriental socio-economicsetting deserves critical review.

Study on Objectives and Strategies for Energy Conservation and Emission Reduction in Transportation Industry during the 13th Five-Year Plan Period in Beijing

Facing increasing passenger and cargo transport demand and limited re-source in the 13th Five-Year period, how to make a breakthrough and substantial progress has become a key issue on planning and the Top-level Design. In this paper we judged and analyzed the current development and potential demand of the energy saving and emission reduction in Beijing traffic industry. Through application of energy and emission prediction model which based on the vehicle activity data, the development goals of “one drop, double control, and triple upgrade” have been put forward. In order to achieve the goal, “5 + 1” development strategies should be implemented, and we also proposed the thinking and recommendations on sustainable development of transportation.

Integrating transportation systems management and operations into the project life cycle from planning to construction： A synthesis of best practices

Guided by the federal highway administration （FHWA）, many states are promoting the implementation of transportation systems management and operations （TSM＆O） pro- grams. TSM＆O is traditionally managed by traffic engineers that focus on optimizing ef- ficiency and operations within a particular corridor utilizing common techniques such as re-timings and access modifications. With the emphasis moving towards maximizing current infrastructure, the practice of managing TSM＆O can be applied to all units and disciplines, within a transportation entity, for increased efficiency. One main reason of the stagnated integration is the lack of policies which could support the integration of TSM＆O strategies within the planning or design stages. This paper provides detailed guidance on how to apply TSM＆O strategies from the planning stages to the construction phase of any general transportation project. TSM＆O programs established around the nation are dis- cussed to understand the current initiatives underway and the best practices to create a robust and performance-based program. The developed TSM＆O project cycle process provides a detailed structure for the potential interactions between phases of a project and department staff as a key to ensure that the program achieves the highest level of opti- mization. Continuous evaluation must be undertaken by the agencies to ensure that theperformance of the system is at an optimal level. Developing performance measures, which accurately describe the objectives of the agency, is critical to ensure the plan to be brought to practice.

产能到位率概念深化及在大庆油田产量预测中的应用

Incorporating Equity Concerns into Transportation Planning and Policies in Urban China: The Status Quo of Practice and Implications

Transportation equity is one of the most recent concerns toward sustainable urban development, which aims to help municipalities or local planning authorities incorporate equity issues into transportation planning and policies, avoiding multifaceted potential inequity outcomes. As for the urbanizing China, do the mainstream planning approaches fail to take equity issues into account? What are outcomes and the potential countermeasures based on Chinese cities' spatial and policy contexts? From the perspective of transportation equity, this article aims to examine the multidimensional effects related to equity concerns of urban transportation planning and policies in China. It suggests that the municipal government should enhance the service level of public transit and efficiently address the inequity issues of transportation systems. The potential measures include: building a multi-modal transit system, linking affordable housing to the transportation system, highlighting the role of non-motorized mode, and offering proper parking spaces around transit stations.

Reflections and Explorations on the Decremented Regulation of Construction Land in the New Beijing City Master Planning

Construction land use has always been a key point for the planning department to practice national transformation strategy. In the new round of compilation of Beijing City Master Plan, the management of construction land use is under the rigid restriction of the bearing capacity of resources and the environment. Setting the upper-limit of the population size, a general strategy of decremented development of urban-rural construction land has been put forward, in order to realize a transition from quantitative expansion planning to qualitative upgrading planning. By "decremented development," "decremented" means a more rigid bottom-line restriction, and "development" means a more scientific allocation of resources. From the master planning level, the new Beijing City Master Plan establishes a comprehensive control framework and restrictive index system from perspectives including land use scale, construction scale, space boundary, urban and rural structure, land use structure, and cross-boundary collaboration; and in practice, it promotes strict management methods by setting up a dismantle-construction land ratio, dismantle-construction building area ratio, employment and residence land ratio, and "two lines and three districts," which is an exploration on the planning management method of construction land use that is stock-based and decremented master planning. Considering that decremented development is a major reform and a special challenge to planning implementation, the Beijing City Master Plan carries out explorations in terms of the planning management method, land policy, jurisdiction division, assessment and supervision, etc.

Factors Affecting Mode Choice of Work Trips in Developing Cities—Gaza as a Case Study

The lack of efficient application of transportation planning process in developing cities, such as Gaza, leads to deficiency in adopting the suitable transport policies to mitigate the transportation problems resulting from urbanization and rapid increase of population. The mode choice model is probably the most important element in transportation planning and policy making. The aim of this study is to develop mode choice model for work trips in Gaza city and therefore investigating the factors that affect the employed people’s choice for transport modes. The model was developed using about two thirds of 552 questionnaires distributed for this purpose. The rest remaining third of questionnaires were used to validate the chosen models. The results of this research show that the factors that significantly affect the choice of transport modes are: total travel time, total cost divided by personal income, ownership of means of transport, distance, age, and average family monthly income. The developed model is able to predict the choice behavior of employed people in Gaza city as it is valid at 95% confidence level. This study can be used by transportation planners to predict the employed people’s behavior and travel demand analysis. The developed model can be used for predicting the future modal split by inputting predicted future value of exploratory variables.
