PROBLEM TO BE SOLVED: To generate expected average speeds of travel across one or more navigable segments in an area covered by an electronic map.SOLUTION: Each segment is associated with: an average speed of travel across the segment; segment data 402 comprising at least one jam probability, the jam probability indicating the likelihood of a jam on the segment; and a jam speed 410 indicating the speed of travel on the segment when it is considered jammed. The method comprises: a step 400 of using the segment data to predict whether a jam condition exists on at least one segment or each of the segments; and a step 408 of outputting the expected average speed of travel across at least one segment or each of the segments as a first speed being the jam speed for the relevant segment or a speed based thereon where a jam condition is predicted to exist, or as a second speed being the average speed for the relevant segment or a speed based thereon where a jam condition is not predicted.SELECTED DRAWING: Figure 8

    【課題】電子地図に含まれる領域におけるナビゲート可能な1つ以上の区分にわたる移動の予想平均速度を生成する。【解決手段】各区分は、当該区分にわたる移動の平均速度、当該区分における渋滞の尤度を示す少なくとも1つの渋滞確率を含む区分データ402及び当該区分が渋滞していると考えられる場合に該区分における移動の速度を示す渋滞速度410と関連付けられており、方法は、区分データを用いて、少なくとも1つの区分又は各区分に渋滞状況があるか否かを予測するステップ400と、少なくとも1つの区分又は各区分にわたる移動の予想平均速度を、渋滞状況があると予測された場合に関連する区分の渋滞速度又はそれに基づく速度である第1の速度又は渋滞状況が予測されなかった場合に関連する区分の平均速度又はそれに基づく速度である第2の速度として出力するステップ408とを有する。【選択図】図8
