As an innovative advancement of Intelligent Transportation System, the Drivers' Smart Advisory System (DSAS) provides wireless information of traffic control as a supplement for conventional signs and signals, which are somehow blocked by obstacles (e.g., trees and trucks) or nature disturbances (e.g., fogs and sun glare). This book specifically evaluates driving performance of the DSAS using sun glare as an example. The system implication was investigated through a driving simulator test. Statistical analyses were applied to examine the negative impacts of sun glare, evaluate the...

There are great potentials of congestion pricing strategies in reducing traffic jams and improving system efficiency due to its ability to promote the efficient use of existing infrastructure. In a congestion pricing system, the design and implementation of the tolling signage is extremely essential in explaining tolling strategies to potential users. This book develops a procedure to evaluate candidate congestion pricing signs and provide design procedure with higher comprehensibility. The developed simulation test method consists of six operational steps, and the evaluation algorithm is...

Well designed signs and symbols provide supplemental information to properly guide motorists to attractions and improve nearby traffic flow and safety. Major Traffic Generators (MTGs) are important regional attractions, events, or facilities, which attract individuals or groups from beyond a local community, city, or metropolitan areas, and require even more proper guide signing due to the large amount of attendance. Concise and legible symbols and/or signs, if properly designed and placed, should be helpful in alleviating traffic impacts by MTGs to surrounding roadway networks. Therefore it...
