As a part of the ongoing IVHS Systems Architecture effort sponsored by FHWA, contractor teams are using traffic and communication simulations in an effort to quantify impacts of implementing their proposed architectures. One aspect of this modeling effort has been the application and modification of a macro-level traffic simulation, INTEGRATION, to capture the effects of proposed evaluatory des...

The Pikes Peak Area Council of Governments Moving Forward metropolitan transportation planning process introduced a Strategic assessment planning framework to the Pikes Peak region. This framework was selected because it integrates multi-disciplinary qualitative and quantitative information from technical experts and regional stakeholders to determine and weight objectives and indicators within...

This paper presents a mobile image-based system for measuring the brightness of highway signs at night time, so that visibility standards for signs can be evaluated and maintained to protect the safety of the motoring public. The system is composed of a high speed IEEE-1394 digital camera, and a laptop computer with a purpose-designed measuring software, which is composed of three modules: 1) I...

This study aims to quantify and compare the life-cycle environmental, economic and social impacts of two pavement materials: namely 10mm Asphalt Rubber Stone Matrix Asphalt (ARSMA10) and 10mm Polymer Modified Stone Matrix Asphalt (PMSMA10). To achieve this objective, a comparative sustainability framework was developed by: 1) combining the Life Cycle Assessment (LCA) with pavement maintenance p...

The Marine Agency-Roads and Transport Authority (MA-RTA) of Dubai-UAE recently undertook a study to develop a new transport policy for service delivery. The goal of the new policy is to increase rider share and use of MA-RTA services. The existing service policy guidelines of the water transit services were barely supported by the loading patterns, existing market coverage, adequate intermodal ...

Transportation agencies’ motor vehicle count programs tend to be well established and robust with clear guidelines to collect short-term count data, to analyze data, develop annual average daily traffic (AADT) adjustment factors, and to estimate AADT volumes. In contrast, bicycle and pedestrian traffic monitoring is an area of work for most transportation agencies. In most agencies, there are a...

Near-fault ground motions are different from ordinary ground motions in that they often contain strong coherent dynamic long period pulses and permanent ground displacements. The dynamic motions are dominated by a large long period pulse of motion that occurs on the horizontal component perpendicular to the strike of the fault, caused by rupture directivity effects. Near fault recordings from r...
