Increased recognition of silver zone (Silver Zone) (equivalent to School Zone): Entry into the aging society – 2000 (7.2%), 2009 (10%), 2020 (14%) and 2030 (20%)
Main installation areas: Senior citizen welfare center, rehabilitation center, nursing home, etc.
Combination with self-protection of seniors: Free supplication of luminous canes, fluorescent vests, etc.
However, accidents in the senior protection zone are not decreasing, and citizens’ understanding of and compliance with the purpose of the system is also low.
Silver Zone Speed-Compliant Induction Solution
Background (Focusing on human factor of driving propensity)
The driver has a willingness and control to obey the law as the legal regulatory message becomes clear
On the other hand, when the external alertness factor is mitigated, the tendency of daily driving tendency (driving speed, compensatory acceleration) is maintained, and the tendency of following the speed of preceding vehicles is maintained.
They overestimate of vehicle performance without clear perception of speed and pedestrian circumstances.
Repeated protection zone and speed limit signs make drivers to continue checking the actual driving speed and driving slowly. (Actively execute intentional deceleration and voluntary control)
Basic Policy Direction
Constant promotion / guidance (combined with media advertisement and directional signs)
→ The importance of the senior protection zone and the need to comply with the speed limit (30 km/h)
Avoid over-installation of enforcement equipment and speed bumps
→ Suppression of propensity for acceleration and deceleration (Kangaroo driving)
Intensive installation of speed limit sign (30 km/h)
→Constant confirmation of driver and inducement of awareness of senior protection zone
Escape from normal driving practice and inducement of rational understanding
→ repeated exposure to senior protection zone speed limit
Provide individual drivers the defensive driving experience
→ Make them to check the difference between the speed limit and the actual speed
Rational driver’s legally limited speed driving ratio improvement
→ Reduce the overall speed of the road to a safe range
Key Guidelines for Integrated Signs
Signs for protected areas (children, seniors, disabled people) are specialized with yellow background
Signs that are applied differently locally are unified – format, specification
A large sign (3m * 2m) is limitedly installed on two-lane minor arterial roads with no speed limit and main arterial roads
Standard for small scale (70%) signs
Example of a luminescent type sign for a senior protection zone
The start and release signs should be placed on both sides of letter type pillar. Luminescent type must be applied to start signs and general signs can be used for release signs
Vertical integrated signs of straight pillar type that installed in the child protection zone must be installed in appropriate quantity in main sites.
Crosswalk signs should be installed with luminescent type signs to prevent pedestrian accidents and to ensure safe driving of drivers.
