This paper examines the acceptability of the implementation of a High Occupancy Vehicle (HOV) lane in the north of Bogota (Colombia), a strategy that is compatible with the policies of the mobility master plan of the city. Although the idea of using HOV lanes dates back to the 70's, it is still a valid alternative which is amply documented that produces positive impacts on travel times, accident rates, greenhouse emissions, among others. The study is based on discrete choice survey experiments which allowed calibrating a multinomial logit model. The calibrated model indicated that the acceptability of the HOV lane is very sensitive to travel times experienced by current car users. The model also identified the segment of the population with the highest acceptability for the proposal, which would consist of women over 31 years old, who travel for purposes related to work

Parking around university campuses has become a major issue in recent decades because of nearby congestion impacts. Objective: To determine the factors influencing parking lot selection, which is crucial to propose adequate parking demand management strategies. Materials and Methods: We evaluate different attributes using a best-worst scaling survey applied at Universidad de la Costa (CUC), Colombia. Using discrete choice modeling techniques, we identified the extent to which selected infrastructure attributes influence parking behavior. Results: Security and cover (roof) availability are the most relevant attributes of parking choice in the case study. Conclusions: Based on our results, we strongly recommend implementing a dynamic pricing rate, roof pricing, removing “reserved spots” and investing in security.

Objective: Design the landing gear for a CESTOL type aircraft according to FAR 23 using: (i) the conceptual designs of the nose and main gear and (ii) evaluate the structural strength of the design by means of finite element analysis at a stage of landing. Materials and methods: The initial requirements for the theoretical development of a preliminary landing gear design are used as a case study. The aircraft’s structure is taken as a base for the different design stages. This analysis is according to a static and level landing condition selected on each gear with a side and supplementary load. Additionally, calculations of geometric parameters and mechanical resistance with preselecting materials for the component analysis to determine and compare theoretical results with finite elements to evaluate the reliability of the design approach. Results and discussion: It is determined to move the main landing gear backward near the cargo area. That allows for better aircraft performance, placing the GC in front of the main gear and avoiding an overturn. However, this load percentage changes in proportion to the longitudinal stability criterion, where it generates an increase in the contribution to the mechanical stress in the structure of the gear. Conclusions: Results obtained about stability, controllability, and structural analysis are acceptable for the regulations of FAA Part 23 with standards associated with airworthiness, being corroborated with theoretical analysis and combined loads.
