PROBLEM TO BE SOLVED: To provide a traffic signal control system and a traffic signal control method for performing efficient traffic signal control on a vehicle group arriving at an intersection.SOLUTION: A vehicle group passing through a point B and running at a recommended running speed reaches a point A after a time consisting of a maximum extendable time of blue time plus a yellow/red lighting time yr. Vehicle group information between t10-t11 about the vehicle group having passed through the point B at a point of time t11, and vehicle group information occurring between t11-t12 that is the same time slot as between t10-t11 can be estimated to take on the same waveform pattern. Immediately before a minimum blue lighting time B1 currently indicated at a point A elapses, a time slot in which the interval between vehicle groups is longest is extracted from among waveform patterns of vehicle group information between t10-t11 obtained from the point B. Then, an extended blue lighting time B2 where a shift count in seconds tn is determined so that yellow and red signals light up in a time slot in which the interval between vehicle groups is longest.
【課題】交差点に到達する車群に対して、効率的な交通信号制御を行う交通信号制御システム及び交通信号制御方法を提供することにある【解決手段】B地点を通過し、推奨走行速度で走行する車群は、青時間延長可能最大時間と、黄赤点灯時間yrとを足した時間後にA地点に到達する。t11時点において、B地点を通過した車群のt10−t11間の車群情報と、t10−t11間と同じ時間帯であるt11−t12間に発生する車群情報とは、同じ波形パターンになると予測できる。A地点の現示の最低青点灯時間B1を経過する直前に、B地点から得たt10−t11間の車群情報の波形パターンの中から車群間の間隔が最も長い時間帯を抽出する。そして、車群間の間隔が最も長い時間帯に黄、赤信号が点灯するように、シフト秒数tnとする延長青点灯時間B2を決定する。【選択図】図8
