DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method, a construction planning method, a construction planning support method, an application support method, and a recording medium storing a computer-readable program for performing a construction plan in a road occupation construction with traffic regulation. About.

[0002]

2. Description of the Related Art Road occupation work involving traffic regulation is frequently performed mainly for infrastructure development in cities. This road occupying work includes works for maintenance of the road itself such as pavement repair, water and sewage works, new laying and replacement of power lines, telephone lines, and gas pipes.

FIG. 9 is a schematic view of a construction site where a gas pipe is laid on a road, for example. A construction section 1 for excluding traffic of general vehicles is provided on the roadway of the road. In this construction section 1, there are a total of three work processes of excavation 2, piping and welding 3, and inspection and backfilling 4. That is, a work zone for performing each of these work processes and a diversion zone for guiding vehicle traffic are referred to as a construction section 1.

In the second excavation step, the trench 7 is dug by the excavator 6 and the excavated earth and sand is discharged by the dump truck 5.
In the three steps of piping and welding, crane trucks 8 sequentially lay, for example, 6 m or 12 m long pipes in grooves 7, and weld
Weld the pipe joints with the welding equipment installed in. In the four steps of inspection and backfilling, the welding portion is inspected by an inspection device mounted on the inspection vehicle 10, and the groove 7 is backfilled by a backfilling machine (not shown) to perform paving. When the above series of works is completed, the work section 1 is moved along the road.

[0005] It is considered that the longer the construction section length of the construction section 1 to be carried out in this one construction is, the higher the use efficiency and the working efficiency of the machine are, and the construction efficiency of the construction is improved. However, construction section 1 is an obstacle to road traffic,
Long construction section 1 due to traffic congestion depending on traffic volume
May not be secured. When the long construction section 1 is installed, a significant traffic congestion occurs, which not only worsens the influence on the surrounding environment and the driver, but also causes a great economical loss.

[0006] The police or other road use permitters, when a construction contractor applies for a road use permit for road occupation work,
A construction permit is granted only when the traffic volume around the construction section where road construction is carried out without construction is below a certain standard, and when it is determined that no significant traffic congestion occurs when carrying out road construction .

[0007] Accordingly, the construction contractor conducts an application before carrying out a survey of the traffic volume around the construction section where the construction is to be performed and confirms that the traffic volume is below a certain standard.

FIG. 10 is a flowchart of a road use permission application process carried out by a contractor. Receive orders from the gas company or the Water Works Bureau for work that specifies the basic specifications such as the pipe laying position (laying map), burial depth, pipe type and diameter (S
1). Next, a construction plan for the construction to satisfy the received basic specifications is made (S2). This construction plan includes the length of each construction section, construction time, and the like. Next, the traffic volume in the section where the above-mentioned construction is to be performed is investigated (S
3).

If the traffic volume is below a certain standard, a road use permission application document is prepared based on the construction plan (S4),
A road use permit application is carried out with the traffic use result attached to the road use permitter (S5). When application permission is obtained from a road use permitter (S6), actual construction is performed based on the construction plan (S7). Then, the construction completion is reported to the construction orderer. When the application is rejected (S6), the process returns to S2, and the construction plan is redone.

[0010]

However, FIG.
The following problems still need to be improved in the construction method of the road occupation construction in which the construction is performed according to the procedure described in (1).

[0011] Based on the traffic volume survey results submitted by the contractor, the road use permitr determines whether or not a congestion will occur due to installation of a construction section of the requested length at the time of maximum traffic volume. Or how much congestion will occur, to determine whether to permit use of the road.

[0012] However, since there is no means for the road permitter to quantitatively evaluate the degree of congestion according to the situation,
Judgments are made by taking into account the results and experience of road construction performed in the past. For this reason, construction is often carried out in short construction sections where traffic jams are less likely to occur.
Since it cannot be determined even if a road use application for a long construction section with no track record in the past is made, the possibility of permission is extremely low.

[0013] Further, since the judgment is based on the actual results and experiences, the judgment does not always correspond to the current traffic situation. Even if similar construction is performed at a place where construction was performed without causing traffic congestion in the past, there is a possibility that a slight change in the situation may cause traffic congestion.

In addition, although the degree of congestion differs between a large number of large vehicles and a large number of small vehicles even with the same traffic volume, evaluation has not been made in consideration of vehicle types such as large vehicles and small vehicles.

[0015] The present invention has been made in view of such circumstances, and a traffic simulation around a construction section using an actually measured traffic volume is performed, so that road construction is actually performed. Method, construction planning method, and construction plan for road occupation with traffic regulation that can estimate the occurrence of traffic congestion and the degree of traffic congestion, minimize obstacles caused by construction, and efficiently carry out construction An object of the present invention is to provide a recording medium recording a computer-readable program for performing a support method, an application support method, and a construction plan.

In the first embodiment system, there are a work orderer 21 such as a gas company or a water bureau, a road use permitter 22 such as a police, a construction company (support request source) 23, and a construction plan creation support company 24. I do.

The construction orderer 21 has a basic specification creating unit 25.
For example, in the case of piping work, basic specifications such as a pipe laying position (laying map), a burying depth, a pipe type and a diameter, and the like are created. The created basic specifications are transmitted to the construction company 23 via a communication network such as the Internet, together with a construction order request. It may be handed in writing.

An application permission is returned to the construction contractor 23, and in the case of application rejection, an application non-permission is returned to the construction contractor 23. In some cases, the application for permission to use the road and the result of the application decision may be handed in writing.

When the construction company 23 receives the basic specifications from the construction orderer 21 together with a construction order request, the construction plan ordering section 27 sends a construction plan creation request to the construction plan creation support company 24 together with the basic specifications, for example, via the Internet or the like.

FIG. 2 is a block diagram showing a schematic configuration of the traffic simulation unit 30. The traffic simulation unit 30 includes a condition input unit 35 and an arithmetic processing unit 36. The measured traffic volume 38 from the measured traffic volume database 37 is input to the condition input unit 35. Also,
Traffic conditions 40 are input from the map database 39.
Further, a construction section length 42 and road use time information 43 as construction conditions set by the operator with reference to the basic specification 41 described above are input. The road use time information 43 is information relating to the time during which a construction section required for construction is installed on the road.

FIG. 3 is a diagram showing the traffic shape including the road shape of the road including the construction section 44 read from the map database 39, the surrounding signal intersection 45, the signal cycle of the signal, and the like. Means that the construction section 44 is set, a one-way construction traffic light 47 is installed, and before the traffic regulation is enforced, the type, position, and traveling of each vehicle 46 traveling on each road on this map. Includes direction and speed information. The actually measured traffic volume 38 is detected, for example, by vehicle sensors installed at various positions on the map.

The arithmetic processing unit 36 calculates the speed change of each vehicle 46 input by the traffic volume 38 in the state where the construction section 44 is set based on the construction section length 42 and the road use time information 43 and the traffic regulation is performed. Calculate (R1). Next, the average speed of the vehicle 46 at each position on the map is calculated (R2). The traffic congestion at each position on the map is calculated from the average speed (R3).

The traffic simulation unit 30 outputs the traffic congestion information 57 calculated according to such a procedure and predicted when traffic regulation in which the construction section 44 is installed is performed.

The traffic simulation unit 3 described above
The detailed operation of the traffic simulation at 0 is reported by the inventors in Japanese Patent Application Laid-Open No. Hei 10-307983.

FIG. 4 is a block diagram showing a schematic configuration of the construction plan creating section 31. The construction plan created in this embodiment is basically similar to the construction section 1 shown in FIG.
As shown in FIG. 5, excavation 2, piping and welding 3, inspection and
By moving along the road the construction section 44 consisting of the work zone consisting of the three work steps of backfill 4 and the diversion zone, the construction specified by the basic specifications 41 is completed. Here, the excavation 2 constituting the construction section 44 and the piping / welding 3
The total of the work zone length obtained by adding the work lengths of the respective steps of the inspection and backfilling 4 and the diversion zone is the construction section length 42 of the construction section 44.

In FIG. 4, a construction plan creating section 31 includes a general planning section 49 for planning the construction of the entire basic specification 41 and an individual planning section provided in the general planning section 49 for planning the construction in each construction section 44. A part 50 and a step-by-step construction planning part 51 which is provided in the individual planning part 50 and plans the construction of the respective work processes of excavation 2, piping / welding 3, and inspection / backfill 4.

The construction plan creation section 31 is activated when the traffic congestion information 57 output from the traffic simulation section 30 satisfies the judgment criteria in the judgment section 48.

In the determination unit 48, information (traffic congestion information) indicating the degree of congestion such as the transit time, the delay time, the waiting time, the number of waiting units, and the congestion length included in the traffic state information 57.
Determines whether or not a predetermined criterion is satisfied in consideration of the place, the traffic situation, and the result data.

In the present embodiment, the determination is made using one or all of the information indicating the degree of the congestion. Further, the type of traffic congestion information is not limited to the above-described transit time and the like, and other types of information may be used. The judgment is made by automatically comparing the traffic congestion information with the judgment standard using a computer or the like. In some cases, the verification is performed by a person.

When the construction plan creating section 31 is started,
Construction section 44 and construction section length 4 currently set in the condition input section 35 of the traffic simulation section 30
2. The road use time information 43 and the basic specifications 41 are fetched, and the process-specific construction planning unit 51 is started.

In the step-by-step construction planning section 51, the setting section 52 of each step work length sets the excavation 2, pipe / weld 3, and inspection / backfill 4 in the construction section length 42 of one construction section 44 described above. Determine the operation length of each operation process. Then, the capacity planning section 53 of the construction machine / vehicle determines the capacity of the construction machine / vehicle necessary for each work process. Further, the work staff planning unit 54 determines the work staff and work time required for each work process.

Thereafter, in the individual planning section 50, the type, number, and number of construction machines / vehicles required to carry out the construction of one construction section 44 are arranged by the placement planning section 55 of construction machines / vehicles / personnel. Create an individual plan consisting of work hours and so on. Then, the individual planning unit 50 outputs the created individual plan document 58 for one construction section 44.

When the individual planning unit 50 completes the preparation of the individual plan for one construction section 44, the overall planning unit 56 of the construction pattern in the overall planning unit 49 starts, and the unplanned part in the basic specification 41 remains. Then, the individual planning unit 50 is started again, and the creation of the individual plan for the next construction section 44 is started. If the traffic conditions in the next construction section 44 can be considered to be substantially the same as the traffic conditions in the previous construction section 44, the previous traffic simulation result is used as it is.

When the setting of all construction sections 44 for all the pipes designated by the basic specifications 41 and the creation of each individual plan in each construction section 44 are completed, the overall planning section 56 of the construction pattern Finish the creation.

The evaluation section 59 evaluates whether or not the construction plan for the entire construction created in this way is optimal. If there is room for improvement, the construction section length to the condition input section 35 in the traffic simulation section 30 is evaluated. 42 or road use time information 43, etc., or the intersection 4
The traffic simulation such as the signal period of the traffic light 5 is changed and the traffic simulation is executed again. Then, the construction plan creation unit 31 can be activated again to optimize the construction plan.

In this case, the evaluation unit 59 determines the construction plan that minimizes the degree of traffic congestion, the entire construction period, and the total construction cost in a well-balanced manner when the created construction plan is implemented, as the optimal construction plan. Then, the construction plan 60 is output.

For example, the construction execution conditions such as the road use time information 43 set in the condition input unit 35 in the traffic simulation unit 30 are shown in FIGS. 6A to 6G.
There are seven types of implementation conditions.

The road use time information is information on the time during which a construction section required for construction is installed on the road.
For example, under the implementation condition of (a), in the map shown in FIG.
The entire road section up to 5 is a permanent construction section throughout the day and night, and the road usage time in this case is 24 hours.

In the condition (b), traffic congestion is likely to occur near each signalized intersection.
It is a daytime construction section, and the road usage time in this part is 9 am
8 hours from time to 5 pm. Since the remaining part is a permanent construction section, the road usage time is 24 hours.

Further, in the last implementation condition (g), the entire road section from one signalized intersection 45 to the other signalized intersection 45 is a construction section only at night, and the road use time in this case is usually 8 pm 1 from time to 6 am the next day
0 hours.

The arrangement of the permanent, daytime and nighttime construction sections in the entire road section between signalized intersections is also included in the road use time information. That is, FIGS. 6B and 6C
When a plurality of types of construction forms (permanent, daytime, nighttime) are combined as in (d) and (f), the road use time information has a plurality of road use times and information on the construction form.

That is, a general buried pipe laying work that requires traffic regulation includes three working steps of excavation 2, pipe welding 3, and inspection backfill 4 as described above. By setting the length of the work zone of each work process to be long, it is possible to increase the construction progress rate. In addition, by setting the length of the work zone long, it becomes possible to introduce a large-sized construction machine, so that the efficiency of construction can be improved.

However, in places with heavy traffic, nighttime work may be required as shown in FIG.
Nighttime construction is a major problem, such as reduced construction efficiency and noise. General road traffic is concentrated in the morning and evening when traffic is heavy. Therefore, by setting a construction start time and a construction end time using a traffic simulation, daytime construction is possible even in a place with a large traffic volume, avoiding a time zone with a large traffic volume.

In the same-day restoration work in which land is completely backfilled in one-day units, a work section length 42 of a certain length is required in order to sufficiently exercise the construction capacity of each process. Therefore, a longer construction section length 42 is set up during times of light traffic,
Efficient construction is possible while minimizing the occurrence of congestion by not performing construction or reducing the construction section length 42 as much as possible during times of increased traffic.

Further, in a place where traffic volume causing traffic congestion does not reach throughout 24 hours a day,
As shown in (a), by adopting the construction method based on the permanent construction section, the excavation 2 and backfill 4 processes can be greatly reduced, and the labor for moving the construction equipment can be reduced, so that the construction is greatly performed. The efficiency can be improved.

Furthermore, traffic volume is an important criterion for selecting construction methods such as night work, daytime work, permanent work and the like, as described above. In general, improvement in construction efficiency is expected as night work becomes day work and then permanent work.

Table 1 shows the construction section lengths and the pipe progress rate (lengthening of laying per day) at each construction time of night work, daytime work and permanent work. Naturally, the progress rate of piping is higher for permanent works and longer work sections.

[0073]

[Table 1]

At a place close to the signalized intersection 45, the degree of congestion varies depending not only on the traffic volume, but also on the signal period, the traffic volume on roads other than the construction section, and the ratio of vehicles turning left or right at the intersection. For this reason, when the construction is performed in a place close to the signalized intersection 45, the conditions for selection of construction time zone and construction section length are generally stricter than in a place where there is no influence of the intersection. .

Then, the construction plan determined to be optimal by the evaluation unit 59 in the construction plan creation unit 31 of FIG.

FIG. 7 is a flowchart showing the entire processing performed by the construction company 23 and the construction plan creation support company 24.

When the construction contractor 23 receives an inquiry for the construction designating the basic specification 41 from the construction orderer 21 (Q1),
A request for creating a construction plan is sent to the construction plan creation support company 24 with the basic specification 41 attached. The construction plan creation support company 24 creates a rough construction plan for the basic specification 41 using the traffic simulation unit 30 and the construction plan creation unit 31 described above (Q2, Q3, Q
4).

Next, the estimate creating section 32 calculates an estimate of the construction cost for the rough construction plan, creates an estimate, and sends it to the construction company 23 (Q5). The contractor 23 confirms the estimate and receives an order for this construction (Q
6), a request for creating a detailed construction plan is sent to the construction plan creation support company 24 (Q7).

The construction plan creation support company 24 creates a detailed construction plan for the basic specification 41 using the traffic simulation unit 30 and the construction plan creation unit 31 (Q8, Q9).

In the basic specification (Q2), there are many cases where there is no information such as the surrounding conditions necessary for creating an optimal plan for each construction section by the traffic simulation and the plan simulation, and a detailed study cannot be made. However, by performing traffic simulation and planning simulation (Q3) based on the minimum information and assumptions, it is possible to create a plan in consideration of shortening the construction period or reducing construction costs at the approximate construction plan (Q4) stage. Yes, estimate (Q
5) can be reflected.

At the stage of the detailed design (Q7), the surrounding conditions of the construction section are clarified, and necessary information can be investigated. Therefore, the traffic simulation and the planning simulation (Q8) are repeatedly performed. By doing so, the construction plan can be optimized. In the present specification, the repeated execution of the traffic simulation and the plan simulation itself is also referred to as construction plan optimization.

When a detailed construction plan for the basic specifications 41 is obtained, the application information creating unit 32 creates road use permission application information to which information of the construction plan and traffic congestion as a result of the traffic simulation is added (Q10). ), Contractor 23
Send to The road use permission application unit 28 of the construction company 23 is activated to apply for a road use permission to the road use permitter 22 (Q11).

When the construction plan preparation supporter 24 makes a road use permission application to the road use permitter 22 on behalf of the construction company 23, the road use permission application information is created and the construction company 23 After receiving the notification of the application permission from the construction contractor 23, the proxy application unit 34 makes a road use permission application to the road use permitter 22.

In the construction company 23, the road use permitter 2
When permission for the application is obtained from 2 (Q12), the construction unit 29 is activated to carry out construction. Specifically, a detailed work instruction is output based on the construction plan (Q13). If the application is not permitted, the road use permission application unit 28 again executes the traffic simulation unit 30 and the construction plan creation unit 3
The construction plan is created using 1. When the construction is completed, a completion report is sent to the construction orderer 21 (Q14).

In the construction method, construction planning method, construction plan support method, and application support method in the road private construction constructed as described above, the orderer 21 of the road construction, such as a gas company or the water bureau, specifies the basic specification 41. When the road construction is ordered from the construction contractor 23, the construction contractor 23 sends a request for creating a construction plan for the road construction to the construction plan preparation support contractor 24 by designating the basic specifications 41.

The traffic simulation unit 30 of the construction plan creation support company 24 calculates the traffic volume 38 before the measured construction section 44 is set, the traffic conditions 40 around the site, the construction section length 42 and the road use time information. The traffic simulation around the site where the construction section 44 is set is performed by using the execution conditions of the construction section 43 and the traffic congestion information 57 resulting from the setting of the construction section 44 is obtained.

When the traffic congestion information 57 satisfies the judgment criteria, the construction plan creation section 31 creates a construction plan for the construction and sends it to the construction contractor 23. The contractor 23 submits the construction plan and a traffic simulation result indicating that the traffic congestion information satisfies the determination criteria to the road use permitter 22 as a road use permission application.

The road use permitter 22 can quantitatively estimate whether or not traffic congestion has occurred and the extent of the traffic congestion when the construction section 44 with traffic regulation is set. In consideration of the above, it is possible to accurately determine whether to permit or reject a road use permit application. As a result, traffic congestion can be minimized or the construction period can be minimized, so that the social and economic impacts of road construction can be reduced.

For example, if it is predicted that the degree of congestion will not be so bad even if a construction section longer than the conventional construction section is set, the longer construction section is set and the construction period is shortened. On the contrary, the social and economic impact can be reduced.

The construction company 23 is permitted to use the road for constructing a road with a long construction section length having a high construction efficiency, so that the construction period and the construction cost can be reduced.

Further, since the construction contractor 23 can accurately perform the traffic simulation around the site where the construction section 44 is set, as shown in FIGS. It is possible to finely set the execution conditions of the construction section length 42 and the road use time information 43 so as to adjust the traffic congestion as little as possible.
