• The number of traffic jams due to traffic concentration is the number of traffic jams excluding the impact of accidents, etc.

4．渋滞緩和に向けたお願い

A little effort from customers will help alleviate traffic congestion. Thank you for your cooperation.

• In-bound attention to the rate of decrease in the slope
  In-bound in a place that is alerting the slowdown, such as slope, for your cooperation to speed recovery!
• Do not reduce the distance between vehicles too much
  Ensure sufficient inter-vehicle distance so that you do not press the brakes while driving!
• Do not change lanes
  Excessive lane changes during traffic jams will worsen traffic congestion!

Topics 1 CA Congestion at Tokyo Wan Aqua-Line Expressway

Tokyo Wan Aqua-Line Expressway, Aqua Line discount for ETC vehicles (H21.8~), opening of large commercial facilities (H24.4~) In recent years, traffic volume has increased and traffic congestion has also increased.

Directed from the Chiba district in Kanagawa towards In-bound line, Kawasaki floating island JCT 4% from 0.2% gradient is changed to front In-bound and around the hill, the previous past the Umihotaru PA Out-bound in the vicinity of the hill, constantly from the usual holiday There is a lot of traffic congestion in the area, and we will extend to the vicinity of the Kisarazu Kaneda Toll Gate.

　今年のお盆期間は、上り線において8月6日（日）、8月13日（日）～15日（火）に15km程度の長い渋滞が発生すると予測しています。

It is known that the peak day of the traffic jam on the Bon festival last year took about 50 minutes longer than when there was no traffic. Since it takes a lot of time to pass when traffic is congested, please cooperate in avoiding times when traffic congestion is predicted (from 14:00 to 22:00 on the In-bound line).

トピックス2　経路選択における所要時間の比較について～ETC2.0プローブデータによる分析結果～

• Due to the development of Expressway, multiple routes can be selected even at the same starting and arriving points.
• Using the section from the Takasaki IC area to the Kawaguchi JCT area as an example, we analyzed the average time required for the customer's route selection last year using ETC2.0 probe data.
• As a result, due to traffic congestion on the Kan-Etsu Expressway, There was a time zone where the time required for the route via the northern Kanto Expressway, which had a long mileage, was about 30 minutes shorter.
• Please check the traffic conditions on the information board on the Expressway or the wide area information monitor of rest facilities such as service areas, and select the route. In addition, please use the traffic jam forecast and leave with plenty of time.

Example of passing through the Takasaki IC from 15:00 to 18:00 on Tuesday, August 16, 2016
