Road name / route name

The name of "Tomei Expressway" is the road name (common name) between Tokyo IC and Komaki IC.The name of the road that runs west of the Komaki IC is "Meishin Expressway."Decree (National Land Development Trunk Road Construction LawAppendix table ofCabinet Order Designating Routes on ExpresswaysThe route name according to (Appendix) is between Tokyo IC and Komaki IC.Daiichi Tokai ExpresswayAnd then, between Komaki JCT and Komaki ICChuo Expressway Nishinomiya LineAnd the overlapping section of the First Tokaijidosha[3].

Currently, only the Shin-Tomei / Tomei and Shin-Meishin / Meishin Expressways use the name "Expressway", but this is the Tomei / Meishin Expressway.plan-constructionIn the process of being promoted, it is widely called "expressway" in the private sector.Popular nameWas used, and was adopted in consideration of the historical background that it became a well-established and familiar name.[4]..However, in the media such as newspapers, it was written as "Tomei Expressway" and "Meishin Expressway" for a while after the opening of Tomei Expressway.[5]..The Chuo Expressway was sometimes called the "Chuo Expressway" when it first opened, and is still sometimes called the Chuo Expressway.The Shin-Tomei and Meishin Expressways, which opened in recent years, are special cases based on the fact that they were constructed as bypass routes for the Tomei and Meishin Expressways, respectively.On the contrary, someservice areaInformation board and some official documents[6]In cases such as "Tomei Expressway," "Shin-Tomei Expressway," "Meishin Expressway," and "New Meishin Expressway," the abbreviations are "Tomei Expressway," "Shin-Tomei Expressway," "Meishin Expressway," and "New Meishin Expressway." There is also.

Relationship with the Shin Tomei Expressway

Parallel to TomeiShin-Tomei Expressway(Hereafter, Shin Tomei) is a road constructed as a bypass line for Tomei.Tomei has a lot of traffic, so traffic jams and accidents are normal, and because the design is old, there are many sharp curves and steep slopes. It was carried out.Furthermore, since the Tomei Expressway is one of the aortas connecting the Tokyo metropolitan area with the central part and Kansai region, logistics between the east and west will be hindered in the event of a disaster.Therefore, the Shin Tomei Expressway was constructed as a bypass route.The Shin Tomei Expressway runs parallel to the Tomei Expressway, and is effective as a bypass route for the Tomei Expressway in the event of a disaster.The Shin Tomei Expressway has a good design and has few sharp curves and steep slopes.Gotemba JCT - Toyota JCTWhen using the Shin-Tomei / Isewangan Expressway, the distance is shortened by several tens of kilometers compared to via the Tomei Expressway, and the time required is often shorter via the Shin-Tomei Expressway.

E1 Meishin Expressway


The concept of the Tomei Expressway was in 1953 (Showa 28).Right-wing Socialist PartyIn May of the same year, in response to the Act of Parliament "National Land Development Central Expressway Business Bill" submitted byMinistry of ConstructionIt started with the "Tokyo-Kobe Toll Road Plan" published by (at that time) as a Tokaido plan to counter this. "National Land Development Chuo Expressway Business Bill" is a leading businessman from Shizuoka prefecture.Seiichi TanakaTokyo is a main highway that runs through the center of Honshu, centered on the "National Land Construction Promotion Federation" formed by members of the Diet who are in line with Tanaka's concept, based on the "National Expressway Concept" that was proposed shortly after the war.・ Kobe Expressway Chuo Expressway (currentlyChuo Expressway) Was the first concrete plan to be constructed, but the "Tokyo-Kobe Toll Road Plan" published by the Ministry of Construction denies the idea of ​​this business bill in a roundabout way.[19],originally,Ministry of InteriorIt became a form showing the movement to inherit and revive the prewar National Expressway concept formulated by[20].

This problem gradually became bigger with the involvement of politicians, and the government limited the section between Tokyo and Kobe, where the planned route was not decided, between Tokyo and Nagoya, and the section between Nagoya and Kobe for the time being. ,Meishin ExpresswayWill be built in advance as[21]..On the Meishin Expressway, during constructionJapan Highway Public CorporationHas hired a road planning technical expert from abroad to plan and design the expressway under the guidance of Dolsh, and Dolsh also served as an advisor to the subsequent Tomei Expressway construction.[22].. Construction of the Meishin Expressway began when the Ministry of Construction issued an enforcement order to the Japan Highway Public Corporation in 1957 (Showa 32), but even at this point the construction route between Tokyo and Nagoya was on the Tokaido (Tomei Expressway). The discussion about whether to make it or the Chuo Expressway was still unsettled, and the route was not decided.[23][Annotation 4]..In the midst of such turmoil, in June 1955 (Showa 30), 6 members of the bipartisan House of Representatives submitted a "National Land Development Transit Vehicle" that said that it would build an approximately 430 km motorway centered on the Tanaka concept. Road Construction Bill ”was passed in April 5000[25].

The Secretariat of the Ministry of Construction consistently supported the Tomei Expressway bill in terms of technology and finance rather than the Chuo Expressway, which prioritizes development. The Chuo Expressway politicians strongly opposed this, and in the end, due to the compromise of both the Tomei Expressway and the Chuo Expressway, the "Tokaido Main Expressway National Highway Construction Law" and "Chuo Expressway Scheduled Route Law" Two laws were enacted, and both the Tomei Expressway and Chuo Expressway lines were settled by starting construction at the same time.[23]..However, in the budget compilation for the following year 36 (1961),Economic Planning AgencyIn 1962 (Showa 37), the following year, the Ministry of Construction ordered the Japan Highway Public Corporation to enforce the Tokyo-Fujiyoshida section of the Chuo Expressway. On the other hand, for the Tomei Expressway, which is economically efficient, we issued enforcement orders over the entire line one after another.[23]..For this reason, the construction of the Tomei Expressway is proceeding smoothly, seven years later. 1969(Showa 44) In May, the entire line was opened due to the operation of Oi Matsuda IC-Gotemba IC.

Commemorative issue

A stamp commemorating the opening of the service was issued on May 1969, 44 (Showa 5).[Source required]..The face value is 15 yen.

Route status

Route branch

Down lineOi Matsuda Interchange From (IC)Ashigara Bus Stop Between near (BS) and on the up lineNihonzaka tunnel (TN) There are two routes on the left and right between the entrance and the Nihonzaka TN exit.They run almost in parallel, and the distance does not change much between the left and right routes.

Oi-Matsuda IC-Ashigara BS has a total of 2 lanes, 2 lanes on the left route and 4 lanes on the right route, with the down lines almost parallel, and the up line is 1 route and 3 lanes.Down lineAyuzawa parking area (PA) can only be entered from the left route.The right route is in the form of branching from the rightmost lane (third lane) by one lane before the branch.Also, if you enter the down line from Oi Matsuda IC, you cannot enter the right route.

In addition, just before the left and right route branch, "Large coins, etc.Although the traffic classification of certain types of vehicles has been canceled, it is difficult for large freight vehicles (excluding heavy trailers) to enter the right route because the distance to the branch is short.[Annotation 5]..Also, heavy trailer[Annotation 6] TheVehicle lane #Traffic division of towing vehicles such as expressways, etc.As a general rule, all lanes on the left route are congested and the minimum speed (50 km / h) or less, or the right route cannot be entered unless the traffic is closed.

The current down line right route was previously used as an up line, but due to an increase in traffic volume, the current up line was newly constructed and diverted to a completely different route.On the way, Ayuzawa PA is installed only on the up line and down line left route, and the site of Ayuzawa PA when it was used as an up line can be seen on the down line right route.

Near the east side wellhead of Nihonzaka TN --The down line is 1 route and 3 lanes using a new tunnel, and the up line is 2 lanes on the left route + 2 lanes on the right route, which is a remodeled conventional tunnel. ..When the renovation of this section was completed, the uphill Nihonzaka PA was near the left and right route branch, and the merging vehicle from the PA was forced to enter the left route.Currently, Nihonzaka PA has been relocated to the Yaizu side and newly built, so even if you use PA, you can enter either route.In addition, the east side of the tunnel was controlled to narrow down the left route to one lane in front and then merge into the right route, but now the lane narrowing control in front is abolished and the destination where it merges with the right route. It was improved to a control method that reduces the left one lane.

  • * 1: The number of down lanes includes the climbing lane between Ashigara BS and Ashigara SA.
  • * 2: The number of up lanes includes climbing lanes.
  • * 3: There is an uphill lane about 4 km from the front of the Otowa-Gamagori IC on the down line.

Compared to the Chuo Expressway, there are many straight lines in the center of the route on the flat ground, and the general section is limited to 100 km / h, but some sections are restricted to 80 km / h.Especially between Oi-Matsuda IC and Gotemba IC, there are continuous steep slopes and sharp curves on the mountain route.In addition, all tunnels except the Yamato tunnel are regulated to 80 km / h.

Like any other highwayrain-Snowfall-(I.e.-typhoonIn stormy weather such asACCIDENTIn the case of construction and construction, speed regulation of 50-80 km / h is applied.

In addition to the above sectionsClimbing lane, There are sections where additional lanes are installed.In particularHills near NagoyaThere are additional lanes with a considerable distance in the relatively rugged section that passes through.Currently, a 6-lane construction is underway between Shimizu JCT and Shimizu IC.

Also, the Shin Tomei Expressway Hamamatsu Inasa JCT - Toyota East JCTAs a temporary measure against traffic congestion until the opening of the road, from October 2011, there are provisional 23 lanes in the 10-lane section between Toyota JCT on the up line-Otowa-Gamagori IC and Miai PA on the down line-Toyota JCT. Was being made[40][41]..In this section, the width of the shoulder is 0.75 m and the width per lane is as narrow as 1 m, so the maximum speed was set to 3.25 km / h (just before the number of lanes increased, it became 60 km / h as a buffer zone. Configuration). After the opening of the Shin Tomei Expressway in February 80, the traffic congestion in the section was significantly reduced, and it was returned to four lanes by the Tomei intensive construction in the fall of the same year.[42].

The up line between Ashigara SA and Oi Matsuda IC isTomei intensive constructionIn such cases, the same section may be closed and the right route of the down line (former up line) may be used as the up line.

Road width

Road width is 3.0 m (Shoulder) +3.6 m (Lane) × 2 (or 3) +0.75 m (central side band) +3.0 m (Median strip) +0.75 m (central side zone) +3.6 m (lane) x 2 (or 3) +3.0 m (shoulder) = 24.9 m (or 32.1 m)[43]And the currentRoad structure ordinanceThe width of each part such as the lane and the shoulder of the road is 0.25 m, but the lane of Tomei is 3.6 m.This is because there was no clear standard for high-standard roads in Japan at that time, and the lane widthAmericaUsed in 12フ ィ ー トIs said to have been adopted[44].

Winter traffic restrictions

Between Tokyo IC and Numazu IC, chain restrictions may be enforced during snowfall, and there are no chain restrictions in the sections west of that, and regulatory measures are taken at the stage of 50 km / h regulation → closed roads during snowfall.High altitude Oi-Matsuda IC-Numazu IC and west of Toyokawa IC where snow clouds flow when a strong winter pressure is placed may be closed.Work such as spraying snow-melting agent is performed in the closed section, but even if the snow stops, the closed measures may be prolonged due to lack of snow removal equipment or freezing at night.

Road facilities

Service area / parking area

  • There were shops in all service areas (SA) and parking areas (PA) except the Yui PA down line, which is difficult to install due to the heavy traffic on the Tomei Expressway, but Akatsuka PA The down line commercial facility was closed on August 2017, 29 (8) due to the rebuilding of the toilet.[45]..Also, on April 2019, 31 (Heisei 4)Toyohashi Main Line Toll OfficeInstalled on the siteToyohashi parking areaThere are no shops in the area.Furthermore, on May 2020, 2 (Reiwa 5), the food court and shopping corner on the Yui PA up line were closed.[46].

At the time of opening, between Shizuoka IC and Yaizu ICKosaka tunnel(Length 270 m)ButexistHowever, it was connected to the Shinnihonzaka tunnel due to the renovation work of the same section.The Shinnihonzaka Tunnel is only 60 m away from the Shizuoka side wellhead, and it was judged that safety could be ensured by providing continuity, so a shade was built in this part to form a single tunnel.

Oi-Matsuda IC-Gotemba IC passes through a considerable distance on the up and down lines, so the number of tunnels on the up and down lines is also significantly different.There are seven more newly opened up lines.

Time required information board

In Tomei, which has a lot of traffic, almost all sections except some sections such as Hamamatsu Nishi IC on the up line-Hamamatsu IC and Mikkabi IC on the down line-Toyokawa ICTime required information boardIs installed.The time required to reach the next IC, the IC 2-3 sections ahead, and the main IC 50-100 km away is displayed.In addition, instead of the above information boards, horizontally long guide boards that graphically display the required time and traffic obstacles are installed at the Tokyo IC destination on the down line, in front of the Okazaki IC, and in front of the up Ashigara SA.In addition, before the Gotenba JCT on the down line and before the Mikkabi JCT on the up line, which are the two route sections of the Tomei and Shin Tomei, the Gotenba JCT via Tomei and Shin Tomei --Shimizu JCT / Shin Shimizu JCT --Mikkabi JCT A large graphic display board that displays traffic information and required time information is installed.In addition, the Okazaki IC on the down line, which is a two-route section of Meishin and Shin-Meishin, is via Meishin and Shin-Meishin.Kusatsu JCTVariable LED display board that displays information on the time required untilNagoya ExpresswayInner city loop lineA large graphic information board that displays route information up to is installed.

Road lighting

The sections where road lights are installed are as follows.

  • Tokyo IC-Gotemba IC
  • Susono IC-Numazu IC
  • Shizuoka IC-Yaizu IC
  • Sagara Makinohara IC-Part of Kikugawa IC, Otowa-Gamagori IC-Part of Okazaki IC, etc.curveIs a continuous section

The standard for setting a continuous lighting section is an average daily traffic volume of 1 vehicles, which should be installed on all lines from Tokyo IC to Komaki IC, but at present, Tokyo IC-Gotemba IC, Shizuoka IC- Securing smooth traffic between Yaizu ICs (before the opening of the new Tomei interchange and ETC discounts, etc.), especially in sections with heavy traffic, or at the base BS where there is frequent traffic congestion Only the sections that are particularly required above are installed.Toyokawa IC-Komaki IC also has traffic volume comparable to that of the Keihin area and Nihonzaka tunnel section, but continuous lighting is not installed here and there are no plans to install it at this stage.In addition, there is a continuous lighting facility between Susono IC and Numazu IC, but it may not be lit depending on the day.

Incidentally,1990 eraUntil the beginning, the continuous lighting section is a steep slope with many curves with the Tokyo IC-Tomei-Kawasaki IC, which is an urban area.Yamakita BS - Ashigara BSIt was only in front (the current confluence of the right and left routes of the down line). It was expanded to the above section due to the new construction and widening work of some sections in the 1990s.

Highway radio (roadside broadcast)

Initially Ashitaka station[Annotation 7]Although it was limited to the east and west of the Toyohashi station, highway radio was installed in many places compared to other expressways due to new construction and section extension.broadcastIt is now being broadcast on all ICs except Mikkabi IC-Mikkabi JCT and Kasugai IC-Komaki JCT.In addition, depending on the location, multiple stations are set up between one IC, and there are places where almost continuous broadcasting is performed.

On the east side of the Toyokawa ICTokyo branch officeBroadcast form that begins with a unique melody by Kawasaki control, the west sideNagoya branchAfter the 4-point chime by Ichinomiya control, it is divided into broadcasting formats that start with "I will inform you of the current highway information at XX hours XX minutes".It used to be divided by the Mikkabi IC, but with the opening of the Shin Tomei Expressway on April 2012, 24, the jurisdiction of the Mikkabi IC-Toyokawa IC was transferred from the Nagoya branch office to the Tokyo branch office. Along with that, the broadcasting format of highway radio was also changed at the Toyokawa IC.

About Kawasaki control, in October 2011 (Heisei 23)Shin-Tomei ExpresswayIn anticipation of the opening, the system was refurbished, changed to machine voice, and information was provided every 2-3 minutes.In addition to the required time information to the main IC, the required time information is provided for each route at stations near the junction connecting to the Shin Tomei Expressway or the connecting route.The starting melody has not changed.On the other hand, with the introduction of the new system, "system failures" that did not occur in the old system have come to occur.Furthermore, in August 2015 (Heisei 27), it was changed to the same machine voice as Ichinomiya control.

In addition, when the Shin Tomei Expressway is partially opened in April 2012, there will be a sign such as "Highway Radio from here" between the Gotenba IC and Toyokawa IC, which is parallel to the Shin Tomei Expressway. Except for the part, it was removed, and many electric bulletin boards similar to the Shin Tomei Expressway were installed instead.In addition, many reorganizations such as the opening of new stations and the absorption and separation of existing stations are being carried out.

One of the characteristics of using Tomei compared to other routes isTokaidoLogistics大動脈Because it is responsible for, the number of vehicles running does not decrease much even at nightLarge carThe ratio of is high.It is also characterized by the fact that there is traffic on par with metropolitan areas throughout the entire section, but in the 22 survey,Shinmeishin Expressway OfKameyama JCT - Kusatsu JCTThe traffic volume increased in the entire section between Tokyo IC and Toyota JCT compared to the 17 survey because the distance and required time between the east of Toyota JCT and the west of Meishin / Kusatsu JCT were shortened. On the other hand, the number of vehicles between Toyota JCT and Komaki IC decreased by about 12,000 (about 15%).Shin-Tomei Gotemba JCT --In the 2012 survey conducted by Mikkabi JCT, the traffic volume of the parallel Tomei Expressway was almost halved at the Gotemba JCT.On the other hand, traffic volume increased between Yokohama-Machida IC-Gotemba JCT and Mikkabi JCT-Toyota JCT, mainly in the unopened section, and traffic congestion in the same section increased sharply.In the latter section, measures were taken to temporarily increase the number of lanes in some sections only during the period until 24 when the Shin Tomei Expressway was extended.

In addition, there is a lot of traffic on the highway regardless of the time of day or day of the week, so even if you increase the number of lanesTraffic jamHowever, it is severe all year round and the road surface is damaged quickly, accompanied by lane restrictions.Tomei intensive constructionBut every year10It is carried out in a construction period of about two weeks.At this time, the traffic jam became heavier than usual, and at the end, rear-end collisions involving large vehicles continued to occur in parallel.General roadVehicles that detour (National Highway No. 1 and National Highway No. 246) will also cause heavy traffic congestion (Therefore, during the intensive construction period, NEXCO Central Japan will adjust the toll on the Chuo Expressway to the same level as the Tomei Expressway and encourage the detour to the Chuo Expressway. There is).For this reason, Tomei is "the most accident-prone expressway in Japan" except for urban expressways.[47]Therefore, the construction of the Shin Tomei Expressway is underway to solve the above problems.

Traffic jam

Odawara Atsugi Road,Hodogaya BypassThere is a lot of traffic between Yokohama-Machida IC and Ebina JCT, where cars from frequently used connecting routes are concentrated, and they are in the same section.Yamato Tunnelnear·Ayase BSCongestion, especially in the vicinity, occurs frequently on Saturdays and holidays.In addition, it started on March 2009, 21 (Heisei 3)."High speed upper limit 1,000 yen"Numazu IC-Fuji IC, which had been a congestion point only during the Golden Week holidaysNakazato BSNear, Fuji IC-Shimizu JCTMatsuoka BSCongestion has begun to occur on weekends in almost all sections, including the vicinity of the Yoshida IC.In addition, mainly on weekday morningsShuto Expressway Line 3Uphill trafficTokyo ICIt may extend past the Tomei Expressway.

After the partial opening of the new Tomei, the traffic congestion in the parallel section of Tomei decreased sharply, but the traffic volume that had been blocked by the traffic congestion in Shizuoka Prefecture began to flow at once, so the section where the new Tomei merged. There is a lot of traffic jams in the area, such as the Torideyama Tunnel on the up line, where the average daily traffic volume was originally relatively low, and traffic jams occur mainly on holidays (from NEXCO Central Japan Congestion Watch Map).

On February 2014, 26 (Heisei 2), due to heavy snowfall, there was a traffic jam of 15 km with the Susono IC at the head, and some cars were stuck for more than 40 hours.
