The main objective of this paper is to describe the traffic characteristics and analysis of spot speed of vehicles using urban roads. Some urban roads in Fayoum City in Egypt are taken as case study. This research work was based on the traffic count and spot speed data was collected by using of moving car method through peak period. This speed is used to estimate the speed distribution of the traffic stream under the prevailing conditions. The speed distributions obtained have many applications such as study of speed trends, estimate maximum, minimum and average speed limits, geometric design elements, and accident analysis. The analysis. The analysis of data collected showed the following results: 1- The estimated values of traffic congestion index are 0.91, and 0.81 for Mostafa Kamel/ Saed Basha direction and Saed Basha/ Mostafa Kamel direction respectively. 2- The average speed values of different vehicle types using Horia street are 34km/hr, 33km/hr and 28 km/hr for Mostafa Kamel/ Saed Basha direction for passenger cars, microbuses, and truchs. For the other direction the values are 33.5km/hr, and 29 km/hr for the same vehicles types respectively 3- Spot speed distributions for different vehicle types are yielded to normal distribution and are fitted by using Chi-Square test. 4- Low spot speeds registered for the study street must draw the attention to improve the driving and geometric conditions on this street.
