公路服务区污水处理系统优化设计研究

在服务区污水处理日益发展的同时,发现目前仍存在处理规模设计不合理和初期启动调试滞后等实际问题。本研究从污水处理量设计原理出发,首次将服务区车辆驶入率引入污水规模设计,更加科学合理,能保证服务区产生的污水全部净化,不会造成基建及设备投资浪费。提出的低水位双泵三相控制进水提升系统,是一种污水处理系统快速启动的安全实效方法,能极大地缩短系统启动调试时间,同时具有快速导排暴雨径流的功能。上述两种方法在江西某服务区进行了实际应用,取得了良好的效果,为服务区污水处理系统优化设计提供了理论支撑和实践经验。     

A highway capacity function in Korea: Measurement and calibration

Capacity functions are important in the model that accounts for the user's route choice behavior based on the traveller's perception of the travel time. This is because a capacity function represents the relationship between the traffic volume and the travel time on the link. The capacity function developed by the U.S. Bureau of Public Roads (BPR) has been used in many countries, including Korea, without much effort to calibrate the parameters for its own transportation environment. Countries other than the United States, however, have distinctive demographic, economic, cultural, and behavioral characteristics; and they might need unique capacity functions for their own environments. Thus, it is important for Korea to have its own capacity function that can appropriately represent the Korea highway environment. Any attempt to model the Korean highway system without using a suitable capacity function might result in inappropriate solutions, because most modeling activities are crucially based on link travel time, and it is the capacity function that furnishes those link travel time. A link capacity function for Korea is calibrated based on a BPR type formula utilizing an alternative method. The alternative method is developed in a bilevel programming framework that uses link volume counts instead of link flow and travel time data. Detailed calibration results are reported.

User perceptions and engineering definitions of highway level of service: an exploratory statistical comparison

The level of service (LOS) concept in the Highway Capacity Manual has been used as a qualitative measure representing freeway operational conditions for over 35 years. One key element that has not been adequately addressed is how road users perceive LOS. This exploratory research examines road-user perceptions of freeway LOS by presenting study participants with a series of video clips of various traffic conditions (taken from cameras on overpasses to allow a complete view of the traffic stream) and asking them their perceptions of LOS. A random effects ordered probability model is then used to statistically link participant-recorded perceptions of LOS with measurable traffic conditions (speed, density, flow, percentage of trucks, vehicle headways) and participant characteristics. The findings suggest that the Highway Capacity Manual’s use of traffic density as a single performance measure for LOS does not accurately reflect road-user perceptions. The statistical analysis shows that a number of attributes besides traffic density determine public perceptions of LOS and that these perceptions vary depending on both traffic conditions and road-user characteristics.     

Uncertainty in the context of highway appraisal

Transport planning is based on traffic forecasts which are subject to great uncertainties. These uncertainties have generally been ignored or, at least, not explicitly included in the planning process. This paper describes the principles behind the estimation of the uncertainty (or range of error) of the forecasts of a traffic model and discusses the means by which this information can be absorbed into the decision-making in transport planning projects. These principles have been applied to the appraisal of a British highway project and throughout the paper reference is made to this project in order to illustrate the results of the practical application of an explicit treatment of uncertainty. It is believed that this approach can and should be developed for application in most areas of transport planning, leading inevitably to an improvement in the quality of the decisions taken.

The innovation of the interstate highway system

Strategies used to deploy technological innovations are central determinants of the degree to which those innovations realize their potential effect on social and economic productivity. The U.S. Interstate highway system was a deployment mechanism for the design innovations of high-speed geometric design and the control of highway access. This strategy was defined by rigid uniform minimum standards of facility design, severely constrained alternatives for configuring the network of facilities, and an inflexible and, in some cases, inappropriate institutional structure for constructing facilities. This strategy compromised the realization of productivity improvements available through the deployment of these innovations. This paper explores the origins of this deployment strategy and generalizes to a discussion of deployment strategies for large engineered systems. It shows that each of the Interstate program's provisions derived from traditions of the agency charged with implementing it and from political expedients embraced to enact the program.
