Unusual congestion that could be caused by an incident or other traffic problems is a major source of delay for drivers in urban areas. Real-time traffic information, the building block for advanced traveler information systems (ATIS), has a promising potential for alleviating such congestion by encouraging and assisting drivers to divert to less congested routes. Traffic information is envisioned to help more informed routing decisions in case of incident-related congestion. Drivers’ routing decisions made when they are faced with such unusual congestion are investigated. The factors that influence these decisions are explored, including the effect of traffic information. A nested logit modeling structure is introduced. This model proved that the nested logit approach is superior than the simple multinomial logit in modeling the choice in cases of incident-related congestion. The model also showed that the decisions not to divert from the usual route and to divert but only around the location of the problem share unobserved terms. Familiarity and usual use of alternative routes did not affect the decision in the case of an incident. Drivers who use more than one route to work do not necessarily switch routes if they encounter unusual congestion. The nested logit model also proved the significance of traffic information, indicating a promising potential benefit of ATIS in alleviating nonrecurring congestion.

An intersection queue jump (IQJ) can be defined as an elevated ramp or side lane that can be used by motorists normally stopped in traffic at an intersection to bypass the intersection and traffic congestion. The feasibility and ultimately the success of an IQJ depend on several factors, including the traveling public's willingness to use the queue jump. Road pricing theory and the results of a recent stated preference survey to gauge the willingness of drivers in Lee County, Florida, to pay for the use of an IQJ are examined. It was found that approximately 54% of surveyed drivers indicated a willingness to pay at least a small amount to use the IQJ. The appropriate toll level is likely between $0.25 and $0.40 per trip. Using the survey data, it was also found that the respondents' stated value of travel-time savings was approximately $5.21 per hour. The toll-price elasticity of IQJ was approximately −0.2 when the toll increased from $0.10 to $0.25, and approximately −0.4 when the toll increased from $0.25 to $0.50. Using logit modeling, it was found that certain driver characteristics, including being married with children and having a household income of less than $16,000 or more than $75,000, increased the likelihood that a driver would use the IQJ. Other characteristics, including being on a shopping trip, being more than 65 years old, and being male, decreased the likelihood that the driver would use the IQJ.
