With today’s ever-increasing traffic demand, more and more signalized intersections are experiencing congestion for longer periods of time. To better quantify oversaturated conditions, it is necessary to accurately estimate oversaturation delay. The generalized delay model, proposed for inclusion in the next update of the U.S. Highway Capacity Manual (HCM), is introduced here. The generalized delay model differs from the model in the 1994 edition of the HCM as it is sensitive to the duration of the analysis period and is not restricted to degrees of saturation less than 1.2. The TRAF-NETSIM microscopic simulation model was used to verify the generalized delay equation for oversaturated conditions. A simulation model was used, because it is extremely difficult to measure oversaturated delay in the field. The study was designed to cover as much of the domain of oversaturated traffic operations as possible. The variability in simulated delays was investigated, and an equation was developed to predict the standard deviation of oversaturated delay estimates. It was found that delays estimated by the proposed generalized delay model are in close agreement with those simulated by TRAF-NETSIM. On average, simulated delays are overestimated slightly, but the error is small compared with actual delays. The proposed generalized delay model is expected to provide a good estimate of actual oversaturation delays that occur in the field.

Impacts of alternative federal milk marketing policies which result in reduced fluid (Class I) milk prices were assessed using a simulation model of the U.S. dairy industry. Results indicated that milk production, farm milk prices and producer revenues were significantly reduced in the Southern and Northeast regions of the country under some options. The regional shares of total U.S. milk production were not significantly altered from those which would exist under a continuation of the current policy.

We study new transaction-level data of discount window borrowing in the U.S. between 2010 and 2017, merged with quarterly data on bank financial con- ditions (balance sheet and revenue). The objective is to improve our under- standing of the reasons for why banks use the discount window during periods outside financial crises. We also provide a model of the decision of banks to borrow at the window, which is helpful for interpreting the data. We find that decisions to gain access and to borrow at the discount window are meaning- fully correlated with some relevant banks' characteristics and the composition of banks' balance sheets. Banks choose simultaneously to obtain access to the discount window and hold more cash-like liquidity as a proportion of assets. Yet, conditional on access, larger and less liquid banks tend to borrow more from the discount window. In general, our findings suggest that banks could, in principle, adapt their operations to modulate, and possibly reduce, their use of the discount window in "normal" times.
