CP Proposal

1.1 Problem Definition

Rescue A-Z is an application that provides

vehicle rescue, repair services and assists

users in taking care of their vehicles

This application is intended to replace

tradi-tional methods so that the user can solve the

problem as quickly as possible

According to Vietnam Register Department, till

December 2020, there are over 4 million cars

and 58 million motorcycle operating Due to

the high demand of traffic transportation, the

rate of damaged vehicles rises as well

Howev-er, the way repair & rescue services works

in Vietnam is still on the traditional side,

there-fore Rescue A – Z was established with the aim

of taking technology advance to solve

prob-lems related to vehicle repair and rescue

ser-vices of Vietnamese with speed

1.2 Problem Overview

Traffic participants experience problems

with their vehicles but lack the knowledge of

solving them

Not aware of nearest repair services, gas stations

Rescue services are not popular, hard to

reach The caller has to use traditional

meth-ods which takes more time than needed and

their quality cannot be assured

In specific scenarios in which the driver does not have time or is not in the rescue cover-age

There is a lack of a reliable review platform for repair services which can connect the people with demand and repair shops con-veniently, most of the contact is via tradi-tional means such as verbal communication

or phone numbers

Many people do not have knowledge of

tak-ing care of vehicles Most of the information

comes from many online, unreliable sources

on the Internet

Approximately, 5.7% of Vietnamese families own cars This ratio in

urban areas is 3 time higher than

rural areas, 9.5% and 3.6%

From 1990 to 2018, the number of motorcycles has risen over 48

times, from 1.209.000 units to

58.170.000 units

Vietnamese car industry has quickly developed in the 3 recent

years The growth rate of the car market under 9 seats reached an

average of 20-30% / year and the car ownership rate in Vietnam is

about 23 cars / 1,000 people (Vietinbank’s auto industry report in

2019)

It is forecasted that in the period of 2018 - 2021, the number of

registered motorcycles will increase by more than 1.12 million

mo-torcycles, the number of motorcycles in circulation will increase

by about 1.15 million vehicles By 2030, the number of registered

motorcycles will increase by nearly 1.5 million vehicles, the

num-ber of motorcycles in traffic will increase by more than 1.62 million

vehicles

==> Personal means of transportation take the lead compared

to public ones in Vietnam.

There is a clear correlation between car

consumption and GDP per capita and the

number of cars per 1000 people of all

coun-tries Vietnam is currently in early stages of

the growth circle Reasonable consuming

growing rate of Vietnam is about 10.5% per

year if looking at the correlation with GDP

per capita of the countries in the region

With each 1% growth in GDP per capita, car

consuming rate per person grows by 1.5%

However, growth rate can be higher and

po-tentially will reach 12-15% per year in the

next 10 years if car price drops and there are

methods to stimulate the rate such as

ban-ning motorcycles in inner city

==> Vietnamese pay much attention to means of transportation.

According to forecasts of LMC and Fredonia foundation, the

worldwide demand for car tires will continue to increase with an

average rate of 3-4% per year in the period of 2018-2020

Viet-nam’s car tires market growth rate is forecasted to reach 8% per

year in the period of 2018-2020, which is two time higher than the

world’s average

Vietnam tires market value growth rate is forecasted to reach 8%

per year in the period of 2018-2020which is 2 time higher than

the world average, and higher than 6% of the developing markets

group

==> Demand for tires increases

==>Demand for repairing, replacing tires increase along with

the need of transportation.

In 2020, the fuel consumption rate in the beginning of May

in-creased for 50-60% compared to the previous period, and the first

10 days of June, fuel consumption increased for 20-30%

com-pared to the previous period

==>The fuel consumption increases.

==>Vehicles demand increases Petroleum supply-demand forecast chart of Vietnam to 2035
