| 摘要： | Traffic congestion is an important aspect of quality of life, mobility and accessibility in urban areas. The economic cost of congestion is in the order of billions of dollars especially for dense urban cities. Besides the congestion which relates to the magnitude of travel time, travel time variability is also studied extensively by researchers as an additional measure for transportation network efficiency. In order to enhance the efficiency of urban traffic flow in New York City, numerous policies have been discussed, including different transportation pricing schemes. Pricing schemes – particularly variable pricing – should incorporate the severity of congestion and levels of travel time variability at different times of day and areas throughout the City. However, most of the existing discussions are based on number of trips and bridge/tunnel crossings in the City, mainly because the necessary data to calculate travel time related measures have not been extensively available. This study utilizes taxis as probe vehicles collecting travel time information in the city 24/7 in the New York City urban network. Two separate taxi trip datasets were utilized to calculate the spatio-temporal travel time patterns covering all boroughs of New York City. The street and avenue travel times in Manhattan are also calculated by projecting origin and destinations onto Manhattan’s grid network. The identified spatio-temporal congestion and travel time variability patterns are discussed within perspective of congestion pricing policy discussions in New York City. |
