NEXCO EAST (Chiyoda-ku, Tokyo, Chairman: Shigejiro Yagi), during Golden Week (Friday, April 25 to Tuesday, May 6), Provide detailed traffic congestion prediction information And at locations where traffic congestion is expected, such as in the sag section "Providing speed recovery information by LED display board" We took measures to alleviate traffic congestion, such as by taking action.

Compared to last year, the holiday pattern in the first half of the period was a stepping stone consecutive holiday, so the number of passengers decreased by about 1.4%, and by promoting measures to alleviate traffic congestion, Approximately 7.0% reduction in traffic volume over 10 km Did. Furthermore, compared to the year before last, despite the fact that the number of units used has increased by approximately 1.2%, Congestion volume of 10 km or more was reduced by about 10.6%, showing the effect of congestion mitigation measures.

In-bound Slope and sag section ^*1 Then, In-bound When you approach a slope, you may unknowingly slow down and cause congestion. In order to alleviate such congestion, Tohoku Expressway, Kan-Etsu Expressway, Joban Expressway, etc., where large congestion was predicted, Providing information to promote speed recovery by using an LED (light emitting diode) display board with excellent visibility The we.

　This time, 27 measures were taken, and as a result, traffic congestion was reduced by about 7% at all measures. Did.

In particular, Tohoku Expressway Out-bound in the vicinity of Hanyu parking area (PA), that was taking measures Traffic speed near the top of the traffic jam has improved and traffic congestion has decreased by approximately 45% There was a day I did

We will continue to implement this traffic congestion countermeasure as it will reduce traffic congestion at a low cost.

At the junction of the interchange (IC), the traffic tends to be extremely biased toward the overtaking lane where you can drive at higher speeds in an attempt to avoid vehicles merging into the driving lane or slow speed vehicles, which causes traffic congestion. In places like this, Eliminating traffic congestion by increasing traffic volume by leveling lane usage Is planned.

this time Take this measure in 3 places Particularly Tohoku Expressway In-bound etc. In sheet piles IC, as congestion mitigation by lane usage leveling, Providing information to promote the use of driving lanes with LED display boards The we. On the day when countermeasures were taken, Lane usage is leveled and traffic congestion is reduced by approximately 21% There was a day I did

Major toll gates in the Tokyo metropolitan area during Golden Week ^*1 The ETC usage rate in Japan was about 74%, an increase of about 6% compared to the same period last year (about 68%). With the spread of ETC, Congested traffic congestion at the main toll gate ^*2 Traffic volume decreased by 99% compared to 2002, immediately after the introduction of ETC However, not only customers using ETC but also all customers passing through the toll gates had the effect of alleviating traffic congestion due to the spread of ETC.

In Tohoku Expressway and Kan-Etsu Expressway, traffic volume in the night/early morning where late-night discounts and early-morning night discounts are applied significantly increased compared to before the introduction of the ETC time zone discount system (2004). And Promoting transportation shifts by introducing a discount system it was done. In the direction of Out-bound, there was a day when there was a traffic shift where the traffic volume increased during early morning and night when the traffic volume was low and the traffic volume at the peak of traffic congestion decreased.

ETC time zone discounts allow you to drive comfortably without getting caught in traffic and reduce traffic congestion, so please continue to use it effectively.

NEXCO EAST 's information site “DraPla (http://www.driveplaza.com)” etc. provide traffic congestion prediction information for Expressway, and the information site of Expressway was released on October 3, 2007 by three companies (NEXCO EAST, Central Japan, West Japan. ) Since the joint “DoraNavi” was renewed to NEXCO EAST alone “DraPla”, about 710,000 traffic congestion forecasts have been used on average per month, which is before Golden Week this year. In the month of April, the number of users was about 1.22 million, about 1.7 times as many. In addition, when comparing the number of passengers used in April of this year and in December of last year, which is before the traffic congestion during the year-end and New Year holidays, it increased by about 24%.

By viewing the traffic congestion prediction information and avoiding traffic congestion, you can drive comfortably and alleviate traffic congestion on Expressway. Please use the traffic jam forecast information.

In addition, NEXCO EAST will analyze the causes of traffic congestion and promote traffic congestion countermeasures effectively and efficiently in order to provide customers with comfortable and reliable Expressway.
