This research was conducted to examine State and local speed laws, regulations, and current practices for setting speed limits. The information for the study was obtained from a review of the literature and a mail survey of State and local highway officials conducted by a Task Force of the AASHTO Subcommittee on Traffic Engineering. Throughout years of experimentation and observation, little consensus has been reached concerning criteria that should be used to establish speed limits. While the 85th percentile speed is considered as a major factor in all States and most localities, the deviations from the 85th percentile that are used to establish the speed limit can result in an arbitrary limit.

Speeding in work zones is one of the most common traffic violations observed by road builders and road maintenance crews. It creates an unsafe environment for road workers and all types of road users. This synthesis is intended to help address this situation by reviewing work zone speed management efforts in Canada and the United States. The report provides an overview of technologies and methods for managing speed in work zones, with topics ranging from posted speed limit reductions and narrowing lanes to portable variable message signs and enforcement. In addition, the report discusses other methods for speed management, including merge control, driver and worker education, and real-time traffic information systems. The report also provides a number of conclusions and recommendations based on the synthesis, which identify some of the key problems and solutions.

The objective of this study was to quantify effects that selected characteristics and adjacent development patterns have on roadway speeds. Based on the results of a literature search and the availability of data for Kansas highways, twenty-seven variables were identified as possibly affecting speeds on rural state highways and thirty-two variables were identified as possibly affecting speeds on urban state highways. Speed data and data for the potential explanatory variables were collected for a total of 539 sections of state highway (186 rural and 353 urban sections). Two approaches were used to develop and test models to predict speeds on rural and urban state highways based on roadway characteristics and adjacent development patterns. The first approach was based on models in the form of multiple linear regression equations. The second approach employed artificial neural networks (ANNs) to predict highway speeds. None of the regression models were entirely satisfactory in terms of their ability to predict the 85th percentile speeds on rural and urban highways within +/-5 mph (+/-8 km/h). A number of regression models are presented, however, they should be used with caution. Two independent databases were used to train two sets of ANN models of rural and urban speeds. The first set of ANN models (Stage 1) was developed using the same data used in the regression analysis. The second set of ANN models (Stage 2) was developed using a database provided by the Kansas Department of Transportation (KDOT) Bureau of Traffic Engineering. The second database contained only those variables that KDOT believed drivers consider in selecting a driving speed. Overall, the Stage 2 ANN models developed in this study were found to perform much better than either the Stage 1 ANN models or the regression models in predicting rural and urban highway speeds.

This synthesis documents information regarding the current state of practice for work zone speed management. The report compiles data, procedures, techniques, and technical issues related to observing and comparing work zone speeds. The speed management measures have been organized into four categories: engineering, operational, enforcement, and public education and outreach. Information included in this study was acquired through a review of the literature, two surveys of state department of transportation representatives in all states, a compilation of state agency public information campaigns, and follow-up interviews with select survey respondents from several U.S. states and one Canadian province.
