Estimation of volume delay functions for arterials and freeways in the western region of Puerto Rico
(2011-07)
Volume Delay Functions (VDF) are formulas developed to describe the functional relationship between travel time and traffic flow in a travel demand model considering the available capacity of the facility. VDF’s are the ...
GPS-enabled mobile phones as sensors in the determination of the components of individual trip chains withouth user input
(2012)
Dynamic Traffic Assignment (DTA) is used to maximize the network’s capacity utilization. Research for DTA is active, but the data to apply it in real world situations is still under development. The solution proposed herein ...
Framework for humanitarian logistics and relief distribution efforts of non-established relief groups in the aftermath of a catastrophic event: Hurricane Maria in Puerto Rico
(2019-12-12)
After massive disasters and catastrophes, the infrastructure and communication systems of a community can be severely affected to the point that their function could be nonexistent. Furthermore, the affected areas are ...
Evaluación del uso de autoscope para conteos automáticos de vehículos en intersecciones
(2006)
This work presents a study that determines which non-intrusive equipment of automatic vehicle detection is better counting vehicles at intersections. After the literature review, the most promising was the technology that ...
Dynamic transportation and humanitarian logistics model: a decision support tool to forecast and prioritize critical supplies distribution during emergency relief operations
(2013)
The optimal mobilization of materials, personnel and relief supplies to a disaster site could be the difference between life and death for the affected population. The purpose of this dissertation is to develop a system ...
Analysis of driver’s performance on a school zone using a driving simulator and an eye tracker
(2019-07-03)
Road safety and speed limit compliance in school zones are critical problems in the United States (US), Puerto Rico, and other places around the world. Research has shown that drivers do not comply with speed limits around ...
Development of the regional intelligent transportation systems architecture for the San Juan Metropolitan Area
(2006)
Several regions around the United States and Puerto Rico have been facing increasingly
complex problems related to their transportation systems. In many cases, the use of advanced technology and strategies collectively ...
Sistema de monitoreo de tráfico y control de interseccion para el Laboratorio de Ingeniería de Transportación
(2009)
In an urban network of vehicular traffic the intersections happen a higher frequency of congestion issues and accidents. Therefore they are appropriate points to place monitoring systems and control of vehicles and ...
Adaptation of VISSIM, a dynamic simulation model, to the traffic behavior at intersections in Mayagüez, Puerto Rico
(2006-05)
The rapid evolution in the sophistication of microsimulation models has encouraged their
use in transportation engineering and planning. Traffic In Towns SIMulation (VISSIM as its
acronyms in German) is a microsimulation ...
A case study of the Tallulah River Road design using context sensitive solution framework
(2012)
The use of Context Sensitive Solutions (CSS) for the project development process is to take in consideration the needs and concerns of different stakeholders in various areas, such as: community, environmental, aesthetic, ...
