A two lane, one-way road with radius of $50$ m is predominantly carrying lorries with wheelbase of $5$ m. The speed of lorries is restricted to be between $60$ kmph and $80$ kmph. The mechanical widening and psychological widening required at $60$ kmph are designated as $w_{me,60}$ and $w_{ps,60}$,respectively. The mechanical widening and psychological widening required at $80$ kmph are designated as $w_{me,80}$ and $w_{ps,80}$, respectively. The correct values of $w_{me,60}, w_{ps,60}, w_{me,80}, w_{ps,80}$, respectively are

  1. $0.89 \:m, 0.50 \:m, 1.19 \:m, \text{ and } 0.50 \:m$
  2. $0.50 \:m, 0.89 \:m, 0.50 \:m, \text{ and } 1.19 \:m$
  3. $0.50 \:m, 1.19 \:m, 0.50 \:m, \text{ and } 0.89 \:m$
  4. $1.19 \:m, 0.50 \:m, 0.89 \:m, \text{ and } 0.50 \:m$
