Delay at Bus Stops of Transmilenio Transport System According to Parameters Measured” in situ”. Case Study Bogotá-Colombia

Paper proposes a dwell-time model at bus stop that predicts transportation capacity of Transmilenio bus system based on operating parameters measured in situ. This bus system is in continuous development, is part of the Integrated Public Transport System (IPTS) in Bogotá-Colombia and follows reticular trunks structure that interconnecting important points of city ensuring a wide coverage. Measurements are performed on Troncal Norte that experiment high demand for travelers across network, has an approximate length of 9.7 km and stops located every 687 m on average. Operates with high capacity buses (articulated and bi-articulated) that run along exclusive lanes, through to intersections controlled by traffic signals. Field techniques developed and tested in previous works for evaluation of main parameter (dwell-time) and other parameters are used for achieving good results. Calculation methodology is widely known (Transit Capacity and Quality of Service Manual, TCQSM) and allowed to obtain satisfactory results in bus stop delay and capacity on stretch with more passengers. Data are collected in weekdays on board of different buses and from stops with more demand, being 2013, reference date of the results obtained.
