Evaluating the Safety Impacts of Flashing Yellow Permissive Left-Turn Indications in Massachusetts
| 项目名称： | Evaluating the Safety Impacts of Flashing Yellow Permissive Left-Turn Indications in Massachusetts |
| 摘要： | The 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD) introduced the Flashing Yellow Arrow (FYA) as a permissive left-turn indication. Massachusetts has since set out to implement this innovative traffic control device at intersections across the Commonwealth. A recent MassDOT retrofit project sought out to convert over 350 traditional steady green ball protected-permissive left-turn (PPLT) traffic signals to FYA protected-permissive operation. With the completion of the retrofit project in sight, this research initiative aims to investigate the safety impact of converting to the permissive left-turn FYA indication. |
