What is an Effective Way to Measure Arterial Demand When it Exceeds Capacity?
| 项目名称： | What is an Effective Way to Measure Arterial Demand When it Exceeds Capacity? |
| 摘要： | We do not have a common approach for measuring demand when such volume exceeds capacity—e.g., unobserved latent demand. For example, suppose over a 15-minute period one observes 900 vehicles passing. It may be the case that this “900” reflects capacity, where the true demand volume is substantially higher. Thus, how can one estimate the demand volume if it exceeds capacity? Candidate methods include, but are not limited to, using vehicle density, queue length, peak hour expansion factors, and travel demand models. (For example, within travel demand models, one may adjust parameters in the volume delay function until the forecast volume, which may exceed capacity, matches the observed volume). Given these possibilities, this research will identify best practices for determining the true forecast demand volume for arterial facilities. |
