The Andean bear (Tremarctos ornatus; 70-195 kg; VU) is the only actual South American bear and its habitat comprises Andean forests. The expansion of the agricultural frontier, the conflict retaliation hunting, the road infrastructure, and the lack of effective preservation practices are its threats. The mountain ranges cover 31.3% of the Colombian territory over 400 m.a.s.l., and constitute the backbone of its river structure. It has 326 Protected Areas (AP’s): 66 nationally, 170 regionally, and 90 locally, which take up 49,528.64 km2, 10.3 % of the Colombian Andean region. 166,779 km2...

Vehicle Assist and Automation (VAA) systems enable lane-keeping and precision docking of transit vehicles. They offer the opportunities of providing high-quality transit service within reduced lane widths. Sponsored by the United States Department of Transportation, this VAA project aimed to demonstrate the technical merits and feasibility of VAA applications in bus revenue service. The VAA Demonstration project was carried out through the four phases of design, development, deployment, and operational tests. In the design phase, the system architecture and requirements were finalized, and...

Reliable origin/destination (O-D) data are critical to many applications in transportation planning, design and operations. Because of the high costs of and challenges in obtaining reliable O-D trip matrices from surveys or other direct sampling methods, estimating O-D trip tables from a readily available data source, traffic counts, provides an attractive, economical alternative. This project investigates one such an estimation method and implements it in a user-friendly software tool called Visual PFE TD. The developed O-D estimation tool can be used to obtain both static and dynamic O-D...
