“…Setting methods of exit advance guide signs has been the subject of much research. Upchurch [ 18 ] evaluated four exit advance guide sign schemes on one- and two-lane expressways through a comprehensive weighting method. Qiao [ 19 ] studied the layout form and setting method of American interchange regional guide signs by comparative experiment.…”

Driving behavior in expressway tunnels is more complicated than in common roadbed sections because of differences in illuminance, visual range, speed perception, and reaction time. To explore the setting method of exit advance guide signs in expressway tunnels and improve the effectiveness of drivers’ recognition of them, we propose 12 layout forms based on information quantification theory. In experiments, UC-win/Road was used to build a simulation scene, and the recognition reaction time of 12 element combinations of exit advance guide signs of different subjects was collected through an E-Prime simulation experiment. The loading effectiveness of the signs was analyzed based on the subjective workload and comprehensive evaluation scores of different subjects. The results are the following. The width of the exit advance guide sign layout in the tunnel is negatively correlated with the height of Chinese characters and the distance between the characters and the edge of the sign. The larger the height of Chinese characters and the distance between them and the edge of the sign, the smaller the maximum layout width of the sign. Considering the driver’s reaction time, subjective workload, sign recognition, amount of sign information, sign accuracy, and sign safety of 12 different information combinations, we suggest that exit advance guide signs in tunnels should be laid out as Chinese/English place name + distance + guide arrow.

“…In a highway context, accessing the alternate route means having to take a right-lane exit while driving on a single direction multilane road with the outer right lane serving as a drive through for traffic that is not to be rerouted and therefore continues its normal trajectory (Fisher, 2004;Upchurch, 2005).…”

Aims and scope of the seriesThe series 'Atlantis Computational Intelligence Systems' aims at covering state-of-theart research and development in all fields where computational intelligence is investigated and applied. The series seeks to publish monographs and edited volumes on foundations and new developments in the field of computational intelligence, including fundamental and applied research as well as work describing new, emerging technologies originating from computational intelligence research. Applied CI research may range from CI applications in the industry to research projects in the life sciences, including research in biology, physics, chemistry and the neurosciences.All books in this series are co-published with Springer.For more information on this series and our other book series, please visit our website at:www.atlantis-press.com PrefaceAdvances in mobility are most clearly illustrated by the spread of motorized traffic and transport, the development of the transportation industry, including vehicle manufacturing and its associated infrastructure. These developments represent one of the main challenges for information science and intelligent technology. The discipline of Intelligent Transportation System (ITS) is widely applied to solve transportation problems including congestion, accidents and pollution emissions.Since our daily life and work are closely related to traffic and mobility, traffic demand has increased dramatically. Following this increase, we additionally have to balance the increasing desire for mobility and efficiency with the societal concerns about traffic problems. Today's traffic demand is predominantly served by individual motorized vehicles, which are the primary means of transportation. As the traffic demand has continuously grown faster than the construction of infrastructure over the last decades, traffic congestion has become a severe problem in many countries. Meanwhile, as vehicle speed is increasing, traffic safety has also become an important and socially relevant topic, which has impact on social and economic developments. Additionally, the environmental impact and energy consumption caused by traffic systems also arouse great public concern.The engineers and scientists in different areas are seeking solutions as to how the traffic system could be used more efficiently and how operations could be improved by using new technologies and new methodologies. Recently, computational intelligence methods have received considerable attention regarding their potential as a powerful technique for traffic and mobility problems. Computational Intelligence (CI) is the study of adaptive mechanisms enabling or facilitating intelligent behaviour in complex and changing environments. As such, CI combines artificial neural networks, evolutionary computing, swarm intelligence and fuzzy systems. The characteristic of 'intelligence' is usually attributed to v vi Computational Intelligence for Traffic and Mobility humans. The concept of intelligence is directly linked to reasoning and...

“…Roughly one-third of drivers made unnecessary lane changes, again highlighting that drivers often misunderstand optional exit lanes. The study recommended diagrammatic advance guide signs and a conventional exit gore sign with pullthrough arrows for the through route and an "Exit Only" plaque over the exit (8).…”

Field Evaluation of In-Lane Pavement Markings in Advance of Freeway Interchanges

Freeway interchanges with lane drops, double-lane exits with optional lanes, and other unusual geometries violate driver expectations and may result in late lane changes and erratic movements near the exit gore. In-lane pavement markings can reiterate the information provided on overhead signs that depict the geometry of the upcoming interchange. Researchers at the Texas Transportation Institute designed and conducted field studies at freeway interchanges to evaluate the operational impacts of route shield and directional arrow in-lane pavement markings. The addition of route shields resulted in better utilization of optional and inside exit-only lanes. In addition, motorists made lane changes farther upstream of the exit and made fewer unnecessary lane changes after the installation of the route shields. The addition of directional arrows also positively affected the lane distributions and lane change rate, but the effect on unnecessary lane changes was not as evident. Researchers concluded that the installation of in-lane pavement markings (either route shields or directional arrows) improved operations and, potentially, safety at the interchanges studied. There is evidence to suggest that a combination of route shields and directional arrows may be more beneficial to motorists than directional arrows alone.
