Factors in Modeling the Car-Following Behavior
Car-following behavior is the result of the interaction of various elements in the specific driver-vehicle-environment aggregation. Under the intelligent and connected condition, the information perception ability of vehicles has been significantly enhanced, and abundant information about the driver-vehicle-environment factors can be obtained and utilized to study car-following behavior. Therefore, it is necessary to comprehensively take into account the driver-vehicle-environment factors when modeling car-following behavior under intelligent and connected conditions.

Fatigue and Aviation Safety
Fatigue has been identified as a safety hazard that has the potential to reduce the optimal performance required of aviation professionals such as pilots. Fatigue as a construct is defined by the International Civil Aviation Organization (ICAO, Montreal, QC, Canada) as a “reduction of mental state or physical performance that results from sleep loss, extended wakefulness, an excessive workload, and or poor lifestyle choices”.

Flight Safety Assessment Based on Quick Access Recorder
The QAR (quick access recorder), as an airborne data recorder, can collect and store multidimensional flight parameter data during a flight. Currently, QAR devices have been widely installed on various types of aircraft. It has been proven by practical experience that the QAR can effectively collect thousands of real-time parameters during flight. These flight parameters can reflect the condition of the external environment, flight attitude, aircraft status, pilot operations, etc. Therefore, they provide objective evidence for flight technical evaluations, safety incident investigations, and the elimination of potential flight safety hazards, which can yield better flight safety.

Forth Bridge Approach Railways
The Forth Bridge approach railways were railway lines constructed in the period 1887 to 1890 to form new main lines on the opening of the Forth Railway Bridge. The Forth Bridge opened in 1890 at the Queensferry crossing, and only local branch lines approached the location. The North British Railway built new main lines and upgraded some existing lines. The increase in passenger traffic resulted in serious congestion at Edinburgh Waverley, which was extended and modernised in the years following 1890.

Freight Distribution in Small Islands
Freight transportation in urban areas represents an essential activity from the standpoint of economic development; the spread of e-commerce (also accelerated by COVID-19) has contributed to increasing the demand for freight distribution over short distances. In most cities, the approaches and measures are often based on new technologies. This research tackles this topic, formulating and solving a distribution problem by linking shipping services with last-mile distribution operated by means of automatic delivery service (parcel lockers). The results show that such a type of service could reduce the user’s waiting time when compared to traditional home deliveries.

Fully Autonomous Vehicle
Fully autonomous vehicles (AV) would potentially be one of the most disruptive technologies of our time. The extent of the prospective benefits of AVs is strongly linked to how widely they will be accepted and adopted. Monitoring and tracking of individuals' reactions and intentions to use AVs are critical.

Gender Disparities in the Urban Public Transport
Gender and public transportation studies are critical for a nation’s social and economic development, particularly in a developing country such as Nigeria. Men and women use public transportation due to their different social roles and economic activities. In other words, good public transportation improves or expands opportunities in health, education, and employment. Consequently, understanding the gender differences in accessibility will be crucial to enhancing existing transport services and helping design more efficient transport policies.

Geo-Design in Planning for Bicycling
Cities have increasingly promoted bicycling as a mode of transport as part of their strategy to develop a more sustainable transportation system. Australia is one of the countries that seeks to promote bicycling in a significant manner. There are two primary barriers faced in this effort. The first is the organizational complexity of planning and of implementing cycling-related projects, which can span across different agencies in government at various levels, from federal to local. Second is the lack of a clear framework for effectively planning a bicycling network using multiple data and tools available to these agencies within a limited budget. The use of a geo-design-based, collaborative, and data-driven framework for planning bicycling networks brings various stakeholders, such as transport planners, urban designers, and academics, into the planning practice, thus overcoming the mentioned barriers. Geo-design is an environmental design framework for complex problems involving the collaboration of different teams and stakeholders, supported by digital computing and communication technologies.

Geometric Design of Suburban Roundabouts
A modern roundabout is an intersection with a circulatory roadway at which the vehicle speed is low, and the traffic is continuous and circulating in one direction around the central island towards the exits at the approach legs. Modern roundabout design is an iterative process that is composed of the following steps: (1) the identification of the roundabout as the optimal traffic solution; (2) the definition of the number of lanes at the intersection based on the required capacity and the level of service; (3) the initial design of the roundabout geometry; (4) design vehicle swept path, the fastest path analysis, and visibility performance checks; and (5) detailed roundabout design if the results of the performance checks are in line with the design recommendations. Initial roundabout geometry design elements are not independent of each other; therefore, care must be taken to provide compatibility between them. An overview and a comparative analysis of the initial geometric design elements for suburban single-lane roundabouts defined in roundabout design guidelines and norms used in Croatia, Austria, France, the Netherlands, Germany, Serbia, and Switzerland is given in this entry.
