As one of the four original pilot studies into disaggregation of the Freight Analysis Framework Version 2 program funded by the Federal Highway Administration, the research team at the University of Alabama in Huntsville (UAHuntsville) has experienced many of the issues and problems associated with the use of such a highly aggregated database. The UAHuntsville Read more »
It is commonly accepted in the transportation planning community that local data is the only legitimate data that can be used to forecast travel. Therefore, large, highly aggregated data sets are often discredited and deemed an inappropriate data source without extensive consideration. Additionally, since freight flow databases are generally large and highly aggregated, freight transportation Read more »
This paper presents a simulation model to determine the impact of various container inspection protocols on the operation of a seaport container terminal. The inspection protocols are A) no inspection, B) container sampling with unloading and inspection coupled and C) inspection after unloading or decoupling inspection from unloading. Any sampling plan using Protocol B had Read more »
This paper presents a modeling approach to determine the impact on throughput on air fleet resources on the operation of airports. The primary constraints for this analysis are i) adherence to schedules, ii) optimization of resource utilization and iii) reduction of operational costs. Any plan for an impact analysis on throughput on air fleet resources Read more »
This paper presents the development of a conceptual framework for simulating interstate traffic. ProcessModel was selected as the simulation package. The framework has been successfully used to model interstate I-65 from Montgomery to Birmingham, AL. The study corridor begins near the Alabama River Bridge north of downtown Montgomery at mile marker 172 and extends north Read more »
The project FAF2 Pilot Project – Utilization of FAF2 Data By State And Local Governmental Agencies, in support of the Federal Highway Administration FAF2 Pilot Project, was to develop methods and procedures to enable State and local governmental agencies to utilize the Freight Analysis Framework 2 (FAF2) commodity origin-destination data and the FAF2 freight network Read more »
The purpose the project Establishing Performance Measures For Alabama’s Transportation System was to research current transportation system metrics and develop a set a performance measures appropriate for establishing the level of performance for Alabama’s multimodal transportation system and the effectiveness and efficiency by which it is able to supply reasonable user access to jobs, goods, Read more »
Modeling of the statewide transportation system is an important element in understanding issues and programming of funds to thwart potential congestion. As Alabama grows its manufacturing economy, the number of heavy vehicles traversing its highways will continue to rise, straining its already limited infrastructure. This project looks to improve existing modeling tools and develop future Read more »
Review research discussing successful implementation of Lean Enterprise in seaport operations with cited examples from Port of Mobile, Alabama.
This paper analyses the effectiveness of applying the Quick Response Freight Manual (QRFM) to model freight transportation. Typically, freight transportation is indirectly modeled or as an after-thought. Increasing freight volumes, coupled with cost saving strategies such as just-in-time delivery systems, require transportation professionals analyze infrastructure needs and make investment decisions that explicitly include freight volumes Read more »
