SPR-4104: Predicting Impact to Traffic Safety and Mobility of Change in Speed Limits for Indiana Freeways
| 项目名称： | SPR-4104: Predicting Impact to Traffic Safety and Mobility of Change in Speed Limits for Indiana Freeways |
| 摘要： | The study will estimate the safety and mobility effects of removing the differential speed limits on rural freeways and raising the speed limits on urban freeways from 55 mph to 60 or 65 mph. It is also possible that the research will confirm the current policy of differential speed limits on rural freeways and the single speed limit on urban freeways as optimal. |
