“…Drivers tend to change lanes while trying to merge from on-ramp to freeway and diverge from freeway to off-ramp in the type-A weaving sections causing sideswipe crashes. Lane change was an important factor affecting sideswipe crashes (Mao et al, 2019). On other hand, sideswipe crashes per hour decrease as width of inside shoulder increases.…”

The efficiency and safety of type-A freeway weaving sections in urban areas are constrained by recurrent bottlenecks. Limited space in freeway weaving sections cause traffic congestion and crashes during peak-hours. Various factors, including length of weaving section, continuity of lanes, and number of lanes will have significant effects on the level of service and safety performance of the weaving sections. Eight years (2010-2017) of crash data in the type-A weaving sections was used in this analysis. The objective of this study aims to evaluate geometric design factors and operational factors on total crashes and each of the four crash types: rear-end, sideswipe, angle, and single-vehicle in type-A weaving sections using traditional negative binomial approach and develop crash modification factors (CMFs) to improve safety in the type-A weaving section. The results revealed that on-ramp traffic per hour, off-ramp traffic per hour, non-weaving traffic per hour, weaving ratio, length of the weaving section, direction of the freeway, width of inside shoulder, and width of outside shoulder were influencing crashes in type-A weaving sections. Furthermore, the estimated crash modification factors (CMFs) result revealed that total crashes gradually decrease as inside shoulder width increases. This implies that widening inside shoulder width have positive effects on weaving section safety. In addition, ramp metering, and advisory warning signs could improve safety in type-A weaving sections.

“…Non-weaving volume was considered equal to the freeway volume prior entering the weaving section minus the off-ramp AADT. Weaving ratio was defined as the percentage of the weaving vehicles out of the total number of the inflow vehicles to the section (Mao et al 2019), which is calculated using equation (1).…”

One of solutions to reduce traffic problems on Jl.AP.Pettarani, Makassar is the separation of paths based on their functions (fast and slow lanes) or called separator. The purpose of this study is to determine the traffic performance at the separator openings, the effect of the length of the separator openings on the degree of saturation and weaving speed. The performance (degree of saturation) of the separator openings based on IHCM 1997 on AP.Pettarani (direction of Sultan Alauddin-Tol Reformasi) during the morning and evening peak hours are 2,054 and 2,113. Degree of saturations for the opposite direction at morning and afternoon peak hours are 1,893 and 1,980. The addition of the length of the separator will increase weaving speed.

This study investigated the relationship between personality states and driving behavior from a dynamic perspective. A personality baseline was introduced to reflect the driver’s trait level and can be used as a basic reference for the dynamic change of personality states. Three kinds of simulated scenarios triggered by pedestrian crossing the street were established using a virtual reality driving simulator. Fifty licensed drivers completed the driving experiments and filled in the Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) questionnaire to measure the drivers’ personality baselines. Key indicators were quantified to characterize the five types of personality states by K-means clustering algorithm. The results indicated that the high-risk situation had a greater impact on the drivers, especially for drivers with openness and extroversion. Furthermore, for the drivers of extroverted personality, the fluctuation of personality states in the high-risk scenario was more pronounced. This paper put forward a novel idea for the analysis of driving behavior, and the research results provide a personalized personality database for the selection of different driving modes.
