| 摘要： | Congestion along arterial systems in New England is often the result of adverse weather conditions, which typically change the normal traffic flow parameters and render the normal signal plans unsuitable. With recent advances in communications and signals hardware, there is a need to explore the feasibility and benefits of implementing signal-timing plans, specifically tailored for inclement weather conditions. The current study has two main objectives: (1) to assess the impact of inclement weather on traffic flow parameters at signalized intersections in northern New England; and (2) to evaluate the likely operational benefits of implementing weather-specific timing plans. To assess inclement weather impact, traffic flow under normal and inclement weather conditions at a signalized intersection were carefully observed over two winter seasons. The weather/road surface conditions were categorized into six different classes, and values for the saturation headways and startup lost times were collected for each weather condition. Statistical analyses reveal that inclement weather does have a significant impact on the values of saturation headways, particularly once slushy conditions start developing or once snow start sticking to the ground. |
