there are 18 bus services from A - R, 3 roads from S - U, 1
expressway V, 1 terminal W.
A is a service that starts/terminates, not a loop service, at
eunos.
B is a 1 way service which operates only in the morning.
C is a service which operates another alternate service after
evening on weekdays, afternoon on saturdays and whole day on
sundays and PHs.
D is a service which also operates another alternate service
similar to C.
E is a 1 way service that operates only during peak hours on
weekdays and unknown for other days
F is a service that starts/terminates from jurong east
G is a service that doesn't terminate at a proper terminal and
which the terminal has no resting place for BCs to rest before
continuing their journey.
H is a service which terminates in a eastern interchange
I is a service which terminates somewhere near a cross-border
place
J is a service which both interchanges it terminates at are
air-conditioned
K is a service which terminates at a western terminal
L is a service which, like G, doesn't terminate at a proper
terminal and which the terminal has no resting place for BCs to
rest before continuing their journey.
M is a service which terminates at a north-eastern
interchange.
N is a service which loops at a road quite near to a MRT
station.
O is a service which starts/terminates at a CBD terminal
P is a service which terminates at a western interchange
Q is a service which terminates at a terminal that doesn't allow
boarding and alighting.
R is a service which terminates at a north-western terminal
S is a road that L pass by, which this is the only main road where
there is 1 bus stop for L to meet other services. after this bus
stop, L will only meet 1 bus service at a smaller road. this
service that L meets terminates at an eastern interchange.
B and J pass by a road T, which B starts service from this
particular road. however B and J will not meet each other at
all.
C & D pass by 2 roads U with their alternate services. however,
C & D pass by in opposite directions (1 direction each for C
& D for whole trip) and both services doesn't touch each
other's direction, nor does it stop at each other's bus
stops.
A & R pass by a expressway V. however, A & R will not meet
each other at all at V though before entering V, A & R meet up
at this road at the west.
A and H intersect each other for 5 bus stops in 2 roads together.
in the other directions. they intersect for 4 bus stops in 3 roads
together. 1 of the place where they intersect/separate is near an
expressway.
A and F intersect each other at a bus stop on a road along an
expressway. after that, A and F does not intersect each
other.
A intersect Q for 2 bus stops at the same road. in other
directions, A intersect Q for 3 bus stops, also at the same
road.
C and P intersect each other for 5 bus stops in 2 different roads.
however, when C is operating its alternate service, both service
intersect each other for 7 bus stops in 4 different roads. in other
directions, C and P intersect each other for 6 bus stops in 4
different roads and 8 bus stops in 5 different roads when C
operates its alternate service.
D and K intersect each other at 2 roads for 4 bus stops each and 3
different roads for 3 bus stops together, which C, D, K and O
intersects. for O, it also intersects K for 1 more bus stop at a
road before both link up to the road which C, D, K and O
intersects. in the other directions, C and K intersect for 4 bus
stops at 3 roads together, D and K intersect for 9 bus stops in a
few roads together before separating and intersecting at another
road for 4 bus stops while O and K intersect for 5 bus stops at 3
roads together. it is unknown of whether C,D and O does still
intersect each other after they separate with K.
F, H and an unknown service terminates at the same
interchange.
I and N starts/terminates at the same interchange. after I & N
departs from the interchange, I intersect N for 1 bus stop at a
road. both of them intersect at the bus stop opposite this, except
that they are going back to the same interchange.
3 unknown services terminates at the same terminal W
E does not intersect any of the 17 unknown bus service, not do they
terminate at the same interchanges/terminals as any of the 17
unknown bus services.
G intersect C, D, O for 2 bus stops on 2 different roads. however,
when G intersect them, C, D & O would be travelling towards
different directions for 1 of the bus stop; the other bus stop C, D
& O would be travelling toward the same place..
H & J intersect with each other for 3 bus stops on 3 different
roads before separating.
H & M terminates at the same interchange. M does not intersect
any of the other 17 services.
P & R intersect each other for 8 bus stops in 3 different
roads.
what are the 18 bus services, the 4 roads and the terminal? give
reasons for your answers. when needed, also show the other bus
stops and roads which the different services intersect at, the
unknown bus service.
