RISK ANALYSIS FOR SEVERE TRAFFIC ACCIDENTS IN ROAD TUNNELS (PART II)Franco Bontempi
IF CRASC'15 - Roma, 14-16 maggio 2015.
The safety in road tunnels is a very delicate issue, since that a minor accident or a failure of a vehicle can degenerate into scenarios that can lead to a high number of victims. For example, on the 24 March 1999, 39 people died when a Belgian HGV carrying flour and margarine caught fire in the Mont Blanc Tunnel.
In the first part of this study has been summarized the operation logic of a specific model for the risk analysis, the PIARC/OECD Quantitative Risk Assessment Model, and how it derives risk indicators. In the second part, a comprehensive risk analysis is performed in a long tunnel in South Italy, accounting for multifaceted aspects and parameters. The analysis is integrated with a sensitivity analysis on specific parameters that have an influence on the risk.
The section 2 of this paper describes the tunnel San Demetrio on which was carried out risk analysis applying the PIARC/OECD QRA model, and in the section 3 are reported the main analysis results. In section 4, conclusions regard to risk analysis applied to real case and about the sensitivity analysis are reported. In particular, the sensitivity analysis has highlighted the most influential parameters in the model.

IRJET- Proliferation of Ground Vibrations Induced by Moving TrainIRJET Journal
This document summarizes research on ground vibrations induced by moving trains. Experiments were conducted to measure vibrations at different distances from a test track equipped with typical railway infrastructure. Vibration levels were found to decrease with distance from the track but increase on platforms and building foundations due to structure-borne transmission. Vibrations were also measured at various heights within a 14-story building near the test line. While most vibration levels were below standards for human comfort, reductions may be needed for buildings within 40 meters of tracks in high vibration areas. The research aims to help predict and mitigate train-induced vibrations in railway and building infrastructure.
Rates of Soft Ground Tunneling in Vicinity of Existing StructuresIJAEMSJORNAL
Soft ground tunneling in the vicinity of existing structures is a major challenge to tunneling engineers. Tunneling works cause inevitable ground movements that may lead to unrecoverable damages to adjacent structures. Tunneling rates significantly affect such risks. However, a guideline that determines appropriate tunneling rates and accounts for the effects of tunneling on the structures existing in the vicinity is not available. Tunneling records in terms of TBM advance speed (AS), utilization factor (U), and advance rate (AR) for tunnels constructed without causing significant risks on the existing structures are presented in the paper.These records are discussed for different types of existing structures.Ranges of these records for tunneling without causing detrimental effects on different types existing structures are recommended.Useful observations are also made on the variation of these records with the ground type and composition and the precautions to be adopted to mitigate the tunneling risks on existing structures.

Effects of Vehicle Running Mode on Rail Potential and Stray Current in DC Mas...PrasenjitDey49
The document discusses how different vehicle running modes impact rail potential and stray current in DC mass transit systems. Field tests on Nanjing Metro Line 1 showed that rail potential was highest in the acceleration and brake modes of vehicles. Specifically, the maximum positive potential occurred during acceleration, while the maximum negative potential was observed during braking. Numerical simulations also indicated that rail potential is significantly higher in acceleration and braking modes compared to other running modes like coasting. The vehicle running mode was found to influence both the rail potential and shifts in buried conductor potential within stray currents.

The document discusses a study examining how well UK water service providers incorporate risk management and resilience as part of a multi-agency approach. The researchers analyzed 38 Community Risk Registers and found inconsistencies in style, structure, and level of detail when assessing risks like water infrastructure failures or drought. They conclude that improved consistency is needed in how water providers engage in and contribute their risk assessments to the community planning process.

If you feel the shaking?
• Stop and not panic
• Information gathering
• Do not evacuate by car
(Now studying the effect
and Balance of the
evacuation by car)
In case of Normal Road?
• Stop once to the left side
• Move the parking, outside
of Emergency Traffic
Road
• Follow the Police
In case of Highway ?
• Stop once to the left side
• Act for the instruction,
assistance and guidance
by police, road manager
• Park to the left side
• Leave the engine key in
car
• Do not lock the door
• Do not leave the valuables

Editor's Notes
Next one, I want to introduce the Influence of Traffic and Transportation after EQ occurred.
After EQ occurred, As Direct damage, Road, Bridges and Railways may be some damaged.
And As Indirect damage on Traffic, Buildings were collapsed and Lifeline like Electric poles falling down may be damaged.
and Some damage of lifeline like pipe damage will be damage to Road. 矢印
Then They will be Debris and obstacles on Traffic.
These damage and debris will be some negative influence such as Interruption of traffic network, Traffic paralysis and Traffic Jam.
And then, by these Influence, Emergency Response such as Search and Rescue, Emergency Recovery will be delay,
and the Damage will be more great.
Next one is the Situation of Traffic and Transportation.
This picture is one location of the Road damage by EQ.
I want to show the Video of Quick recovery at this location.ビデオ
ビデオ
This video shows how quick recovery.
90% of Highway were recovered 11 days after EQ
Especially This location were recovered within 6 days.
How to recovery. This is just image
1. Remove the collapsed pieces.
2. And Cover the crushed stones.
3. Pave asphalt.
40 to 50 person had works per day.
最初から1分50秒まで。
Seismic Intensity in Tokyo was Maximum Upper 5.
Road and Railway were not so serious damaged.
But, Metropolitan Expressway, the Highway of center area were all Closed for Quick Inspection like Safety Check.
And All Railway and Subway were also stopped by Emergency Stop and Safety Check as Dr. Hayashi already mentioned.
クリック
Therefore, Heavy Traffic Jam was caused.
And Many people returned home on foot.
I also returned home on foot from company about for 15 kilometers.
And, Many Location were filled with Many people who have difficulty returning home
Because Usually many people commute to company by Train from very far.
I want to show the Video for these situation in Tokyo.ビデオ
ビデオの中身
The station staff has announced the train has stopped.
Many people have waited.
Many people have waited for using the public phone.
Many people had to stay because they have difficulty returning home.
Many people were not panic and had settled down. I want to emphasize it.
Expressway were closed.
Next one is Bridge damages.
Some Bridges were falling down by Tsunami like this picture.
Finally, as Closing, I want to introduce the Some Rule for Drivers in Japan and Current Situation for Traffic in Japan.
The Rules for Drivers when the EQ occurs.
First one is if you feel the shaking??
In case of this, Of course Stop and not panic. we have to gather the Information.
and Important one is Do not evacuate by Car.
But, in case of the Great East Japan EQ, the Time of evacuation by Tsunami is very limited.
So, now we started to study the Effect and Balance of evacuation by car for especially Tsunami.
Next one is in case of Normal Road.
Of course firstly have to stop once to the left side because Japan is the left-hand traffic.
Then, have to move to the parking or go outside of Emergency Road according to the Police.
Next one is in case of Highway.
This is almost the same. Stop once to left side and have to Act for the instruction, assistance and guidance from Police and Road manager.
Last one is in case of Evacuation as soon as possible to leave the car on the road. such as the Fire is coming near or something.
Firstly have to park to the left side. and have to leave the engine key in car and Do not lock the door.
Can you imagine it?? I think you can’t imagine it. I can’t imagine it Because someone can stole it.
But This is ideal instruction, Rules in Japan.
By some Questionnaire in japan, 70% of drivers answer that they will do that.
After that Police can move to somewhere.
Finally I want to show the Video of Field Training Exercise(FTX) for Traffic Control as a Current Situation.
It is held on September 1st every year. September 1st is Disaster Management Day in Japan.
This Video is exercise in Tokyo on that day this year.
And after the Great East Japan EQ, this Exercise is larger than before.
In this Exercise, 120 locations were actually closed by Police.
Some traffic control.
and It was a first time to collaborate with near prefectures.
Then some emergency vehicles have passed.
