Increasing the population, the number of vehicles,  and activities in Gresik Town causing social and economic problems that are highly dependent on road transport. These problems arise because of the imbalance problems such as the high volume of traffic and the increasing number of people  living  along  the  Gubernur  Suryo  Road.  The  method  used  in  this  research  is  descriptive study. This method used to look for the amount of capacity and degree of saturation that affect the activities on this road. Data collection techniques using observation and geometric data. While the flow of vehicles using MKJI 1997 method. From the effectiveness side, the road capacity is smaller than planned capacity due to the side barriers and the growth rate of the vehicle in line with the population increase. From the identification of problems, volumes of traffic is high, amounted 2969 smp/hour. Performance of road being dropped LOS = 1.91 (F), due to the high volume of traffic that passing through this road is not comparable with the capacity (1548.36 smp/hour) and Degree of Saturation (DS) greatly affects the traffic flow on Gubernur Suryo Road of = 1.91 smp/hour. The high  delay  and  side  barrier  amounted  317  smp/hour.  Side  barrier  can  be  resulted  from  the calculation  of  total  amount  divided  by  the  capacity,  the  result  is  0,20  smp/hour.  It  affects  the smoothness  of  traffic  flow  because  the  density  of  traffic  and  intersection  of  roads  are  not  well planned, where the distance of each t-junction is quite far one another. Traffic engineering is used to solve the traffic jam problems on the Gubernur Suryo Road and along the market road. It is expected that the government can curb the tricycles parking and vehicles along the road so that traffic jam can be resolved soon.

To assess the quality of road traffic organization on environmental indicators, two methods of five regulations operating in the Russian Federation, which take into account the parameters of traffic flow, affecting the volume of emissions Pollutants. The parameter that affects the results of calculations in both methods is the average speed of movement. In real-world conditions on urban highways there are areas where the traffic flow is uneven (braking, acceleration, stopping), which entails an increase in the amount of pollutants from vehicles. At the same time, this uneven traffic is largely due to the existing the road design and traffic engineering on certain elements of the road network. This is the basis for the development of a methodology for calculating pollutant emissions to assess the quality of the traffic engineering, taking into account the uneven flow of traffic.

The work, based on previously little available for research, as well as materials and documents found in archival institutions, reflects the legal basis for ensuring road safety in 1948-1953, the state and organizational and legal measures taken in the field of combating accidents in road transport at the republican level by the example Ukrainian Soviet Socialist Republic. Attention is focused on the key problems that determine the development of the road safety system, the measures taken, their effectiveness, mistakes and achievements. Measures to counteract accidents in vehicles are investigated from a historical and legal standpoint, a critical and detailed analysis of decrees and orders of the government, departmental regulatory legal acts. It was found that the presence of a significant number of administrative decisions of the republican authorities of Soviet Ukraine, although it was a rather progressive step for its time, did not fully take into account the reality of achieving the set goals, local conditions and peculiarities. At the same time, the functioning of the emerging road safety system was significantly hampered by the lack of a unified national policy in the context of the rapid growth and development of the country’s automobile and road complex.

The tourism industry in Zimbabwe has experienced fluctuating trends in its growth since the dawn of the new millennium. The Ministry of Tourism and Hospitality Industry undertook a visitor exit survey in 2015/2016 period. The purpose of the study was to gather visitors’ views on Zimbabwe as a tourist destination in order to guide policy formulation on the sector. One of the objectives of the survey was to assess the visitor perceptions of Zimbabwe as a competitive tourist destination. Questionnaires were administered to departing visitors at the country’s three international airports and seven border posts during the period July 2015 until June 2016. The results of the survey indicated that 77% of visitors use road transport to enter into the country. The survey also showed that 18% of visitors to the country travelled by air. It is recommended that that the government accelerates the implementation of the open skies policy so as to attract more direct international airlines to fly into the country. It is also recommended that the government undertakes massive improvement of the road infrastructure in the country so as to encourage the geographical distribution of tourists within the country. It is finally recommended that the private sector and the national tourist organization, Zimbabwe Tourist Authority (ZTA) engage international tour operators and persuade them to develop and promote fly-drive tour packages to the country.

The highway is one of the infrastructure for the smooth traffic. One part of the road that are considered necessary to be analyzed and evaluated is an intersection. Three Gadut intersection is non signalized intersection. The traffic flow is quite dense, and lack of discipline of road user factors competing space to pass the crossing, resulting in congestion is very influential on traffic conditions at peak hours in the morning, afternoon and evening. Prior to conducting the survey, the first to do is survey the condition of the intersection that includes geometric characteristics and traffic volume. From the analysis of environmental data, side friction factor to the junction of three Gadut is the criteria being. Rated capacity (C) the smallest is 3706.3 smp/hour, the degree of saturation of 1.1 smp/hour. This value is over the limit permitted values manually indonesian road capacity of 0.8 to 0.9 (1.1> 0.9), it is concluded that the traffic flow is the crossroads of three Gadut saturated traffic flow. The queue probability value between 128.8% - 157.4% with a total delay largest average 11.57 seconds/smp. It is concluded that the chances of a queue at the intersection of three Gadut very large, so it could cause congestion.

As the city’s economic and cultural center, the urban Central Commercial Districts (CCDs) are rapidly developing, which always brings the heavy traffic jam in the city. In this paper, the traffic flow of CCDs was analyzed, and the traffic flow guidance evaluation model was established. Firstly, according to the travel time function, traffic flow was allocated to the road network of the CCDs by the dynamic assignment model, and the heavy-traffic roads were identified. Then, traffic flow guidance measures mainly including forbidding straight, left turn, or right turn were given, and the evaluation model above was applied to select the optimal measure. Finally, with VISSIM simulation software, the model was applied to the Tianjin Binjiangdao CCD, which illustrated that the satisfied guidance measure can be selected effectively.

Road transport plays an important role in India’s economy. It enables the country’s transportation sector to contribute 6.1% towards India’s GDP. The road network in our country is considered as a critical factor to the country’s development, social integration and security needs of the country. The Government of India has promoted foreign investments in highway projects to bring out high standards and quality. India’s road network carries over 65% of freight and 85% passenger traffic. The traffic volume carried by the national highways almost exceeds the designed traffic volume, and hence the desired speed cannot be achieved. Thus, widening of highways becomes necessary. The population growth is also to be considered and hence provision for future widening is to be provided. Our paper deal with the geometric design for widening of NH-9 is carried out using MX-Bentley software as per IRC specifications. This design includes horizontal and vertical profiling throughout the stretch of the road, according to the existing topographic data. The radius of the curve has been increased to make a smooth curve. Also, the vertical profile has been designed based on the allowable gradient and sight distances. From this, accommodation of more traffic volume and increment of design speed seems to be possible.

Functional reciprocity of all transport sectors with their infrastructure support is most evident in ports. The port of Split, integrated in Split’s traffic intersection, is a striking example of uniqueness of Split-Dalmatia County as a traffic and economic centre of Central Dalmatia. The development of City’s harbour for passenger traffic and the North Port for cargo traffic has determined already set constellation of relations of maritime, road and rail traffic, and their mutual interference. The road transport and activities with regard to hinterland services generate economic development in which Split is no exception. This estimate is based on changes that can be expected in terms of redistribution of traffic flow in the central and southern Adriatic and the greater role of road transport, with Split having an increasingly important role.


KS Tubun Street is a street in Bogor, which has a fairly high vehicle volume and become one of a high-traffic jam area. This is caused by KS Tubun Street is the main road for road users from Jakarta and Bogor. Traffic jam problem that occurs due to the confluence interchange of traffic flow and traffic lights settings that are not proportional to the volume of vehicles across the road. Optimization of traffic flow at KS Tubun Street performed by the stages of forming a model of traffic flow, determining the density and velocity of the vehicle is based on the Greenberg model, and determining the length of the traffic lights to avoid a buildup of vehicles. The result is a traffic flow model with distance and time parameters. The density of vehicles that occurs on the streets of KS. Tubun street based on the Greenberg model between 180 to 240 unit car of passanger (ucp) with the average velocity of vehicles 15 to 19.5 km per hour. The density of vehicles on KS. Tubun street can be break down by increasing time. Traffic light cycle time can be reduced for 8 seconds with the red light glowing time is 80 seconds and the green light glowing time is 62 seconds.

In civil engineering, particularly in the field of traffic engineering, it was possible to measure traffic performance by way of surveying the traffic flow, velocity, and density. The current traffic survey is commonly conducted by surveyor who manually calculates the movement of mode of transportation using traffic counter and survey form. Such method was definitely way too costly and time consuming in rendering the traffic data. Therefore, this study aims was to create application design products for technology retrieval and vehicle traffic count calculations, as well as traffic behavior analysis. This research was used Research and Development (R & D) method. The data accuracy was maintained through check and control to make sure that the inputted data were precisely the same with the results of the display on the application. This application called PRIFACOUNTER that can be operated personally in android OS hand phone. On the basis of the research, it was revealed that some variables and steps in the application concept were definitely needed to determine traffic behavior consisting of traffic flow, capacity, and degree of saturation. Since anyone can use this application, it will reduce the time in order to analyze the traffic performance.  


In General, two problems need to be solved in the traffic management system: road safety and capacity. In this paper, it is proposed to use a calculated way to optimize the cycle of a traffic light object in order to ensure the maximum capacity of the node of the road network. The calculation method is based to determining the optimal ratio of the number of lanes intended for vehicle traffic and the duration of a cycle of the traffic light object. Keywords capacity, street and road network, traffic flow, stop line, width of the roadway
