This paper describes the development of adaptive lighting system during night time, as the highest fatal traffic accidents occurs on curve roads at night time. Night time driving with existing conventional headlamps is particularly unsafe because it does not provide illumination in the right direction on curve roads. Due to this constrain, we need to understand an alternative technology solution to improve visibility for driver at night time during curve road. Headlamp swings in the horizontal direction by sensing steering angle and vertical by sensing distance between subject vehicle and next vehicle. So, when a person turns their car, the headlamp of the car also turns according to the steering angle so that the person driving the vehicle will have better vision.

The aim of the work was to design and fabricate an optimized low cost cargo-bearing tricycle which will fulfill the market demand in terms of cost and functionality, and also suitable for Nigerian roads. The integral construction produced a stronger and lighter vehicle which is very cheap when compared to the existing models in the market. The structure can withstand various static dynamic loads, which implied that the body shell is capable of bearing the various frame stresses. The arrangement of the various body panels to form a unitary structure of sufficient strength helped to resist the forces that act in the vehicle body. The floor and roof panels resist the sagging effect caused by the weight of the occupants and cargo. The stresses range from 3.2 MPa to 37.8MPa. The torque of 1372.71N was required to accelerate the tricycle and was derived from multiplying the tractive effort by the radius of the tire used. The material used for the chassis frame (cold rolled steel) has yield strength of 220.6 MPa, while point of maximum stress is 37.8 MPa giving a factor of safety of about 5.0 which is within a safe range. The objective of the research was fully met as the optimization of the existing tricycles was achieved in terms of ergonomics and strength, as well as in the cost effectiveness of the product.

The importance of chassis in a vehicle cannot be over-emphasized, as it forms the cross-section for the attachment of the various components as well as the body. Also, the suspension systems serve a dual purpose – contributing immensely to a vehicle’s balance for enhanced safety and driving pleasure, as well as for isolating the occupants from unnecessary bumps and vibrations. The aim of this work is to design and analyze vehicular chassis and springs in order to fabricate an optimized load-bearing tricycle. In the design consideration for the chassis, selection of suitable shapes and cross section of chassis members were adopted. Moreover, the reinforcement of the chassis side and cross member joints, as well as various fastening methods were achieved. In the design, the spring rate K was calculated to be 24273 N/m, which is the amount of energy required to compress the chosen spring by one meter. The force exerted by a compressed spring upon the tricycle for equilibrium restoration was calculated to be 1699.11N, while 228.96mm was calculated and adopted as the spring free length. The careful and meticulous selection of the materials used to produce the chassis yielded optimum performance at low cost, it was produced with a 2.5mm thickness mild steel hollow square pipe, with high yield strength to provide the tricycle the support it requires to be able to carry the stipulated load of 755 kg.
