Do you feel Automated Level / Railroad Crossings (i.e. Without Manual Intervention) of opening /closing gates have an edge over manual railroad systems in terms of prevention of pedestrian accidents,collisions of vehicles with trains i.e. safety measures ?.


Do you feel if "Level Crossing Ringtones" i.e. Warning audible alarm bells are generated before 10-15 minutes to a Smartphone / Cell Phone Automobile / Vehicle driver can help him / her to slow down the vehicle before reaching the Level / Railway Crossing". ?.

The Level Crossing Ringing tones will ring the alarm bells audible sound as "Level Crossing Ahead at this Specific Geographical Location".  i.e. Smartphone / Cellphone Application / program design for this functionality.


Can the above Smartphone Application / program be design and developed ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: > Do you feel Automated Level / Railroad Crossings (i.e. Without Manual Intervention) of opening /closing gates have an edge over manual railroad systems in terms of prevention of pedestrian accidents,collisions of vehicles with trains i.e. safety measures ?.

Yes. With MIL grade sensors to detect the arrival of a train a few minutes ahead, MIL grade electronics, and automatic lights, gates etc. The system will have to be fail-safe, though - redundancy for power supply, control electronics, sensor and equipments.   


> Do you feel if "Level Crossing Ringtones" i.e. Warning audible alarm bells are generated before 10-15 minutes to a Smartphone / Cell Phone Automobile / Vehicle driver can help him / her to slow down the vehicle before reaching the Level / Railway Crossing". ?.

I think 10-15 minutes would be too early. About 5 minutes for choosing an alternate route; a minute or slow for slowing down. Would have to be in tandem with a reasonably accurate geopositioning system.


> Can the above Smartphone Application / program be design and developed ?.

Yes, it would be quite simple to develop. Provided the mechanism to trigger the event (railway crossing gate is closing, train is approaching etc.) is in place.

Do you feel if "Level Crossing Ringtones" i.e. Warning audible alarm bells are generated [b] before / in advance 10-15 minutes [/b] to a Smartphone / Cell Phone Automobile / Vehicle driver can help him / her to [b]slow [/b] down the vehicle before reaching the Level / Railway Crossing". ?.

The Level Crossing Ringing Tones will be different from incoming telephone calls ringtones.

The Level Crossing Ringing tones will ring the alarm bells audible sound as "Level Crossing Ahead at this Specific Geographical Location".  i.e. Smartphone / Cellphone Application / program design for this functionality.

Application Database of all Level / Railroad Crossings (Latitude, Longitude) , XML document could be useful in this context.

Key Point :  "Ringtones should be generated before 10-15 minutes i.e. some distance in km/miles before the level crossing whether pedestrian walking on the road, driver driving a two wheeler, three wheeler , four wheeler vehicle on the road to the Smartphone / Cellphone User" .

This is required before for slowing down the vehicle or walking slowly anticipating danger of a train crossing the level crossing well in advance i.e. 5-10 minutes before.
The audible alarms will be alerted to the Smartphone / Cell Phone /  Tablet User with a  Span of One Kilometer (1 km) Boundary Distance before approaching a level crossing.

Level Crossings Geographical Systems data in terms of location i.e. latitude, longitude, city, state will be already available with the US Railways. This data can be forwarded to the Smartphone application developers cos viz Google, Microsoft, Sun, Apple etc for designing and developing the Smartphone GPS Application dedicated to Level Crossing Warnings.

Answer

Yes. The accuracy of standard GPS is more than what would be required for this.

As I see it, putting in place sensors to detect the arrival of a train a few minutes ahead at each level-crossing would be the major challenge - both in terms of logistics and financial viability.
