Determining Peak Hour Factors for Capacity Analysis
Journal of Transportation Engineering, 2011Considering the peaking effect over a short time period is important because queuing might build up and take substantial time to discharge. Traditionally, the peak-hour factor has been used to quantify such a peaking effect. The Highway Capacity Manual (HCM) suggests a design value of 0.92 for congested urban areas and 0.88 for rural areas, if no field

Analyzing and Forecasting Peak Load Hours
2021 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2021The paper considers the problem of forecasting the peak load hours for an upcoming month using artificial neural networks. To forecast the peak load hours, an indirect method is used based on forecasting the total energy consumption in a region for the next month.

Transportation Engineering Journal of ASCE, 1976
Transit routes radiating from the CBD are typical of most city bus operations. This type of routing has existed since the late 1920’s with major changes primarily in the form of longer and more routes as the city grows. The major innovations away from this trend, the demand responsive systems, have met with varying degrees of success and in general ...

Prediction of Hour of Coincident Daily Peak Load
2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2019To manage the power system well, it is important to keep the balance between the electricity supply and its demand. For many utilities, consumers need to pay additional money for the electricity during the peak time on days with the highest demands – coincident peak pricing. Therefore, if the consumers are informed the daily load peak a day or hours in

Variability of Peak Hour Factor at Intersections
Transportation Research Record: Journal of the Transportation Research Board, 2005A peak hour factor (PHF) is used to convert hourly traffic volume into the flow rate that represents the busiest 15 min of the rush hour. Past research indicated that PHF had a strong impact on traffic analysis results. The common practice is to use a default value recommended by national or local guidelines or to use limited field observations.

Energy storage sizing for peak hour utility applications
2015 IEEE International Conference on Communications (ICC), 2015In future smart grids, energy storage systems (ESSs) are expected to play a key role in reducing peak hour electricity generation cost and the associated level of carbon emissions. Considering their high acquisition, operation, and maintenance costs, ESSs are likely to serve a large number of users. Hence, optimal sizing of energy ESSs plays a critical

On the Accuracy of the Simple Peak Hour Approximation for Markovian Queues
Management Science, 1995We empirically explore the accuracy of the simple stationary peak hour approximation (SPHA) for estimating peak hour performance in multiserver queuing systems with exponential service times and periodic (sinusoidal) Poisson arrival processes. We show that the SPHA is very good for a range of parameter values corresponding to a reasonably broad ...

The Battle for Ratings: Peak-Hour Schedules
2001Increased choice is usually advanced as the main purpose of technological change in broadcasting to give the audience more channels from which to select. It is therefore assumed that greater diversity of content or presentation will attract more interest and this, combined with the growth of leisure time, should enlarge audiences and total viewing.

Development of Peak-Hour and Peak Directional Factors for Congestion Management Systems
Transportation Research Record: Journal of the Transportation Research Board, 1996A statewide congestion management system involves the application of large amounts of traffic data to a large number of roadway links at a detailed level. A procedure has been developed to identify congestion on roadway links at a macroscopic level using daily volume counts. Daily volume counts are used to determine a.m. and p.m.
