Research output: Contribution to journalArticlepeer-review


The Highway Capacity Manual (HCM) did not originally contain an arterial planning methodology, but the state of Florida perceived an acute need for one in order to meet its obligations for growth management. Such a methodology was developed, documented, and implemented throughout the state. The methodology was firmly based upon the HCM detailed analysis procedure but had assumptions and defaults that allowed a range of planners to use it effectively. The basic construct was to provide tables of design volumes v and annual average daily traffic that could be achieved for various levels of service and signal spacings for the default parameter values. Two computational tools, implemented in the form of spreadsheet templates as being the most user-friendly and open approach, were provided to users so that they could modify the default settings or specify particular signal spacings and such. The methodology has been in widespread use in Florida, it has served as the basis for the arterial planning technique incorporated into the last update to the HCM, and other states have requested information. The experience with the implementation, including training needs and common user questions, is recounted.
