This study is concerned with using multiple approaches for analyzing safety at unsignalized intersections. This was investigated by analyzing total crashes, one of the most frequent crash types at unsignalized intersections (angle crashes) and crash injury severity. Some of the developed methodological techniques in this study are considered recent and have not been extensively applied. Massive...

1 Weaving is defined as the crossing of two streams travelling in the same direction along a 2 significant section of the road without the assistance of traffic control devices. Merging and 3 diverging vehicles need to make one or more lane-changes in a limited space and time, 4 determined by the weaving section length. This situation creates intensive lane-change 5 maneuvers, combined with hea...

For most ofthe last 50 years, to promote a safe banking system, the U.S. Congress has imposed interest rate ceilings on bank deposits. Federal legislation passed in the wake of the 1930s banking crisis prohibited banks from paying any interest on checking accounts and authorized the Federal Reserve Board of Governors to set upper limits on the rates banks could offer on time and savings account...

The identification of crash hotspots is the critical component of the highway safety management process. Errors in hotspot identification (HSID) may result in the inefficient use of resources for safety improvements. One HSID method that is based on the empirical Bayesian (EB) method has been widely used as an effective approach for identifying crash-prone sites. For the EB method, the negative...

Crash prediction models have been very popular in highway safety analyses. However, in highway safety research, the prediction of outcomes is seldom, if ever, the only research objective when estimating crash prediction models. Only very few existing methods can be used to efficiently predict motor vehicle crashes. Thus, there is a need to examine new methods for better predicting motor vehicle...
