Embodiment Construction

[0021] Embodiments will be described with reference to the drawings.

[0022] figure 1 The configuration of the traffic state predicting device 1 of one embodiment is shown. The traffic state prediction device 1 is configured as a server installed in an information center for providing traffic information. The traffic state prediction device 1 predicts a traffic state based on traffic state statistical data created by collecting vehicle travel information, which is information related to travel of vehicles on roads. The traffic state predicting device 1 wirelessly transmits traffic information including predicted traffic states. The vehicle-mounted device 2 is mounted on a vehicle. The in-vehicle device 2 receives the traffic information wirelessly transmitted from the traffic state predicting device 1, and displays the traffic state in each area based on the received traffic information.

[0023] Traffic state forecasting device 1 comprises communication device 10, statis...

Abstract

A traffic situation prediction apparatus for predicting a traffic situation based on a traffic situation statistical data is disclosed. The traffic situation prediction apparatus includes a map information storage and a controller. The apparatus determines, in response to an update of the map information, whether a specific factor affecting a traffic flow has emerged based on a difference between the map information before and after the update. The apparatus identifies an effect on the traffic flow resulting from emergence of the specific when the specific traffic flow effect factor has emerged. The apparatus predicts the traffic situation by incorporating the identified effect into the traffic situation predicted based on the traffic situation statistical data.

Description

technical field [0001] The present disclosure relates to a traffic state predicting device that predicts a traffic state based on traffic state statistical data created by collecting information related to running of vehicles on a road. Background technique [0002] As one type of traffic state predicting device, a traffic jam predicting device is well known (for example, refer to Patent Document 1). The traffic jam prediction device accepts input of factor information concerning information related to factors of traffic jam generation, such as roads of narrow width and the like. The device predicts generation of traffic jams caused by factors indicated by the factor information. The device predicts traffic jams by using the predicted results and a traffic jam database accumulating past traffic jam information (information related to past traffic jams). [0003] Patent Document 1: JP-2010-14556A [0004] According to the device described in Patent Document 1, a user input...
