OBJECTIVE To analyze the behavior temporal of road-traffic injuries (RTI) in Valledupar, Colombia from January 2008 to December 2012. METHODOLOGY An observational study was conducted based on records from the Colombian National Legal Medicine and Forensic Sciences Institute regional office in Valledupar. Different variables were analyzed, such as the injured person's sex, age, education level...

The Belt and Road initiative, recently embarked on by China, aims to improve cross-border infrastructure in order to reduce transportation costs across a massive geographical area between China and Europe. We estimate how much trade might be created among Belt and Road countries as a consequence of the reduction in transportation costs (both railway and maritime) and find that European Union co...

Costs associated with traffic externalities such as congestion, air pollution, noise, safety, etcetera are becoming “unbearable”. The Braess paradox shows that combating congestion by adding infrastructure may not improve traffic conditions, and geographical and/or financial constraints may not allow 5 infrastructure expansion. Road pricing presents an alternative to combat the mentioned extern...

the aim of this study was to determine the optimal cutting cycle in an uneven-aged beech forest in the north of iran. first of all, a logistic growth model was determined for an uneven aged forest. then, the stumpage price was predicted via an autoregressive model. the average stumpage price of beech was derived from actual timber, round wood, fire and pulpwood prices at road side minus the var...

For more than a decade, Vehicle-to-X communication has been a flicker of hope in the urge to make our roads safer. Numerous research projects advanced the underlying technology. Many technological hurdles were taken such as reliable sensor-based detection of local dangers, e.g., traffic jams. However, researchers have only recently begun to systematically investigate suitable user interfaces fo...

Shape grammar rules are increasingly applied in urban simulation. Even though many network 1 design standards propose shape grammar rules, little is known of the measurable impact of these 2 rules on the performance of transport networks. This paper provides a general definition of 3 shape grammar rules for transport network design. Different rules are evaluated regarding a 4 comprehensive obje...

BACKGROUND AND AIM: The study aimed to assess the frequency of head and face injuries in motorcyclists who had an accident and to find out the relationship between helmet use and frequency of these injuries. METHODS: A cross-sectional study with multi-stage sampling method provides data on the injured motorcyclists with road accidents. Data came from a registration form which has documented inf...
