Book Description
The RHODES-ITMS Corridor Control project addresses real-time control of ramp meters of a freeway segment, with consideration of the traffic volumes entering and leaving the freeway from/to arterials, and the regulation of these volumes via real-time setting of ramp metering rates.

Book Description
RHODES is a traffic-adaptive signal control system that optimally controls the traffic that is observed in real time. The RHODES-ITMS Program is the application of the RHODES strategy for the two intersections of a freeway-arterial diamond interchange. This report addresses the latest phase of the RHODES-ITMS Program that resulted in a field test in the City of Tempe, Arizona. In summary, this phase involved: (i) the integration of the RHODES logic within the signal controller; (ii) the validation of the RHODES logic using "hardware-in-the-loop" simulation; (iii) the integration of the RHODES algorithms within Tempe's traffic management system; (iv) the deployment of RHODES for the field test; and (v) the data gathering and evaluation of traffic performance "with" and "without" the RHODES logic

Book Description
This report documents the work performed and the results obtained on the RHODES - Integrated Traffic Management System (ITMS) Project. The project addressed the design and development of a real-time traffic adaptive control system for Freeway-Arterial Diamond Interchanges using the concepts underlying the RHODES traffic-adaptive signal control system. The traffic "controls" at a diamond interchange are the two sets of traffic signals located at the arterials, on both sides of the freeway, and the ramp meters at the on-ramps to the freeway. The RHODES-ITMS strategy considers, in real-time, the vehicle arrivals and the queues at the intersections and the on-ramps to optimally set these signals, also in real time, to decrease the overall delay of all the vehicles which use the arterials, the frontage roads parallel to the freeway (if they exist) and the ramps at the interchange

Book Description
The RHODES-Integrated Traffic Management System Program addresses the design and development of a real-time traffic adaptive control system for an integrated system of freeways and arterial roads. The goals of this project were to test coordinated, adaptive ramp metering using the Multi-Objective, Integrated, Large-Scale, and Optimized System (MILOS) software on a major urban freeway. A 7-mile eastbound segment of I-10 in Phoenix, just west of the I-10/I-17 Interchange, was chosen as the study area because of the availability of data, and because of recurring congestion.

Book Description
This report documents the work performed on the RHODES Project Phase II(a) which is a continuation of the RHODES Project Phase I. Phase I explored concepts for models and algorithms for real-time traffic- adaptive control systems for street networks. Phase II(a) focused on further development of some of these algorithms and on performing some preliminary laboratory experiments with these algorithms using simulation models. The control architecture of RHODES is based on a hierarchical decomposition of the overall traffic control problem with three levels in the control hierarchy: network load control network flow control, and intersection control.

Book Description
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book Description
A respected resource for decades, the Guide for the Care and Use of Laboratory Animals has been updated by a committee of experts, taking into consideration input from the scientific and laboratory animal communities and the public at large. The Guide incorporates new scientific information on common laboratory animals, including aquatic species, and includes extensive references. It is organized around major components of animal use: Key concepts of animal care and use. The Guide sets the framework for the humane care and use of laboratory animals. Animal care and use program. The Guide discusses the concept of a broad Program of Animal Care and Use, including roles and responsibilities of the Institutional Official, Attending Veterinarian and the Institutional Animal Care and Use Committee. Animal environment, husbandry, and management. A chapter on this topic is now divided into sections on terrestrial and aquatic animals and provides recommendations for housing and environment, husbandry, behavioral and population management, and more. Veterinary care. The Guide discusses veterinary care and the responsibilities of the Attending Veterinarian. It includes recommendations on animal procurement and transportation, preventive medicine (including animal biosecurity), and clinical care and management. The Guide addresses distress and pain recognition and relief, and issues surrounding euthanasia. Physical plant. The Guide identifies design issues, providing construction guidelines for functional areas; considerations such as drainage, vibration and noise control, and environmental monitoring; and specialized facilities for animal housing and research needs. The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities. This updated and expanded resource of proven value will be important to scientists and researchers, veterinarians, animal care personnel, facilities managers, institutional administrators, policy makers involved in research issues, and animal welfare advocates.
