Location of global logistic hubs within Africa based on a fuzzy multi-criteria approach

“…Extensive surveys on this domain are for instance presented in Alumur and Kara (2008) and Farahani et al (2013), showing that location models based on operational research often ignore criteria that can only be qualitatively assessed, such as country stability, life quality, and infrastructure quality (Long & Grasman, 2012). In order to get a holistic view, Murthy and Mohle (2001) claim that good performance criteria for evaluating potential locations should include both quantitative and qualitative assessments and suggest that a decision regarding a location could be efficiently addressed using analytical Multi-Criteria Decision Methods (MCDM) (Long & Grasman, 2012;Zavadskas & Turskis, 2011). Following this perspective, a significant number of articles have applied MCDM to this class of problems.…”

Modeling aggressive driver behavior at unsignalized intersections

“…The number of rejected gaps and the total waiting time were obtained through a gap study that conforms to the methodology recommended in Transportation Engineering Basics (Murthy and Mohle, 1993). The through-traffic speed was estimated from playbacks of the video recording, whereby the time required by through vehicles to travel a pre-determined distance was recorded on screen, and the estimated speed was calculated as the ratio of distance over time.…”

Traffic Congestion Analysis of Asaba Road Using Volume to Capacity Ratio and Speed Performance Index

“…Space mean speed, on the other hand, is an average of spot speeds but considers spatial weighting rather than time weighting. Space mean speed is often used for traffic modelling, assuming that all vehicles are measured over the same road length (Murthy and Mohle, 2001;Garber et al, 2011;Mannering and Washburn, 2013). The space mean speed is as expressed in equation 3.…”
