4 Requests for alleviating traffic congestion

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

  1. 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!
  2. Do not reduce the distance between vehicles too much
    Ensure sufficient inter-vehicle distance so that you do not press the brakes while driving!

    Excessive lane changes during traffic jams will worsen traffic congestion!

Topics 1 CA Congestion at Tokyo Wan Aqua-Line Expressway

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

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.

During this year's Golden Week period, it is predicted that there will be a long traffic jam of approximately 15km on the In-bound lines from April 30 (Sun) and May 4 (Thurs) to 5 (Fri).

We know that the peak day of congestion last year during Golden Week took about 1 hour and 10 minutes more than when there was no traffic. Since it takes a lot of time to pass when traffic is congested, please cooperate in avoiding the time zone (around 12:00 to 22:00 on the In-bound line) where traffic congestion is predicted.

Topics 2 Comparison of time required for route selection
~ Analysis result by ETC2.0 probe data ~

  • 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, the time required for the route via the Northern Kanto Expressway, which has a long mileage, is Time zone that will be shortened by about 20 minutes had.
  • Please use the traffic jam forecast and leave with plenty of time. Also, check the traffic conditions on the information boards on the Expressway and the wide area information monitors of rest facilities such as service areas, and select the route.
