日本における高速道路サグ部における交通渋滞は，同じサグ部ボトルネックであっても様々な交通需要条件で発生する．サグ部の交通渋滞発生の不確実性は，様々な各車両の追従挙動特性に違いがあるためだと考えられる．本論文では，サグ部における交通渋滞発生に影響を与える各車両の追従挙動特性の定量的影響分析研究の取組みの現状を報告する．まず，勾配影響を加味した追従挙動モデルを提案した．計測された車両軌跡データを使い，各車両の追従挙動パラメータを推定した．車両間のパラメータ分布の相関評価と分類を行った．

It is of great importance to analyze right-turning behavior at signalized intersection given high accident records related to right-turn vehicles, which also helps provide valuable insights into safety assessment of signalized intersection. This study aims to analyze the right-turn vehicle behavior in protected right-turn phase by considering the influencing factors of geometric characteristics and signal operation. It was found based on empirical modeling results that the right-turn vehicle behavior is closely related to geometric characteristics such as intersection angle and setback distance of stop bar. Furthermore, in order to make a balance of both positive and negative impact, the potential strategies may bring upon safety performance of signalized intersection, all the influencing factors related to right-turn behavior were summarized and evaluated. Finally, the necessity of employing microscopic simulation to enable a comprehensive evaluation of surrogate safety meausure (SSM) at signalized intersection was examined.

Language：Japanese Publishing type：Research paper (scientific journal)

Quantifying the effects of crosswalk length and signal timing on pedestrian walking speed is an important requirement for providing a rational safety assessment at signalized intersections. This study investigates the effects of pedestrian green time (PG), crosswalk length and pedestrian crossing direction on pedestrian walking speed at signalized crosswalk. It is assumed that the pedestrian walking speeds consist of two components v1 and v2 at two consecutive halves of crosswalk. Empirical analysis shows that the longer crosswalk tends to induce the higher walking speed. Pedestrian walking speed increases as PG proceeds. Furthermore, a comparison of pedestrian speed models for PG and PF (pedestrian flashing green time) demonstrates that pedestrian walking speeds at PF are higher and more variable than at PG. The sensitivity analysis helps understand how these models behave depending on change of each variable.
