The project involves construction of $10\mathrm{.}000$ residential units consisting of count $2000,1+1$ apartments, count $3500,2+1$ apartments, count $4000,3+1$ apartments and count $500,$ selfcontained family houses.

$60\%$ of the units is projected to be occupied by government employees and $40\%$ to be occupied by private sector employees. $2+1$ and $3+1$ units are mainly reserved for government employees and $1+1$ and private units are reserved for private sector employees. $1$ parking space is included for $1+1$ and $2+1$ units and $2$ parking spaces are reserved for $3+1$ and private units.

Some governmental agencies have a special interest in this residential development such that their employees will reside in this development. Therefore, the designers can estimate that $75\%$ of all government units are projected to travel by busses each weekday morning and evening and $40\%$ of all private sector units are projected to travel by busses. Remaining percentages are projected to travel by cars. Each bus can replace $15$ cars. All the cars allocated to each

dwelling is assumed to be used during the morning and evening rush hours that occur between $06\mathrm{.}00-09\mathrm{.}00$ and $17\mathrm{.}00-20\mathrm{.}00$ with an equal distribution.

The commercial development at the center of the residences is expected to draw $50$ trucks each day between $09\mathrm{.}00$ and $17\mathrm{.}00,$ with an equivalent effect of $5$ cars per truck. The commercial center is also expected to draw $5\mathrm{.}000$ cars between $09\mathrm{.}00$ and $17\mathrm{.}00.$ Between $20\mathrm{.}00$ and $06\mathrm{.}00,$ the expected traffic within the residential development is expected to be very low and out of consideration. The roadway, once complete is also expected attract an immediate daily traffic of $10\mathrm{.}000$ vehicles per day.

The rate of increase in traffic is estimated to be $\%1\mathrm{.}1$ percent annually.

Estimate the required number of lanes that reach this residential development based on the projected traffic for $15$ years. Select the highest hourly estimated traffic based on the given information. The ${30}^{th}$ highest hourly factor for the attracted traffic is $0\mathrm{.}1.$ The directional distribution is $60\%$ and $40\%.$ Draw a bar chart showing the hourly flow rates for the respective times. The design speed is $90k\frac{m}{h}$ and the topography of the roadway is rolling terrain.

Determine the stopping sight distance and the passing sight distance $($even if the design calls for a multi$-$lane design$).$

Estimate the minimum horizontal curve radius.
