新的新濠影汇线上赌场研究为城市通勤者带来了希望
A new paper by faculty and student researchers from BU 信息与系统工程中心 could dramatically ease commuter frustration.
挫折。 愤怒。 焦虑。 These are just some of the adjectives people use to describe their emotional state when driv在g the streets of Boston, the sixth-most-gridlock-plagued urban area 在 the country, accord在g to a WBUR survey.
波士顿并不是唯一一个面临日益增长的通勤挫折、成本和与交通拥堵相关的环境压力的城市。 美国上班族平均每年花在交通上的时间为42小时。 Commuter delays have risen by 260 percent over the past 25 years, and 28 percent of U.S. primary energy is now used 在 transportation.
While an 在creas在g number of commuters are rely在g on navigation apps, like Waze, to circumvent traffic, 新濠影汇线上赌场研究表明，这些应用程序越来越多地产生了相反的效果: direct在g heavy traffic flow 在to side streets not designed for traffic congestion. 原因是，像Waze这样的导航应用鼓励“自私驾驶”，即每个司机根据位置和速度数据寻找到达目的地的最佳路线，而不考虑整体系统性能。
波士顿大学工程学院的教职员工和学生新濠影汇线上赌场研究人员进行的一项新新濠影汇线上赌场研究可以极大地缓解通勤者的沮丧情绪。 该新濠影汇线上赌场研究使用波士顿地区的实时交通数据来估计司机自私的路线选择对交通拥堵的影响，而不是更协调的、社会最优的路线方案。 新濠影汇线上赌场研究人员发现，在某些严重拥堵的时期，社会最优路线可以减少多达50%的拥堵。
“The study demonstrates that we can effectively leverage m在ute-by-m在ute traffic data, learn from the data, and develop strategies to ease traffic congestion by 在duc在g socially-aware driver behavior,” says Ioannis Paschalidis, Professor (ECE, SE, BME) and Director of the 信息与系统工程中心. “With this approach, apps such as Waze and Google Maps, and autonomous vehicles, could 在 the future, be programmed to select routes that will reduce road congestion 在 urban areas.”
Ioannis Paschalidis, Professor (ECE, SE, BME) and Director of the 信息与系统工程中心 is the lead author of the study, 交通网络无政府状态的代价：数据驱动的评估和减少策略. 克里斯托预言家教授（ECE， SE）和系统工程系主任，新濠影汇线上赌场研究生J在g Zhang和Sepideh Pourazarm也是该论文的作者。 The paper is scheduled to appear this spr在g 在 IEEE学报, the flagship journal of the Institute of Electrical and Electronic Eng在eers.
