In urban areas, competition for road space at junctions is one of the major causes of congestion and accidents. Routes chosen to avoid conflict at junctions have a mutually beneficial effect which should improve circulation and reduce accidents. A prototype design tool has been developed to provide for traffic management based on such routes. The mathematical model behind the design tool works with a given road network and a given O-D demand matrix to produce feasible routes for all drivers in such a way that the weighted sum of potential conflicts is minimised. The result is a route selection in which all journeys from origin i to destination j follow the same route. The method which works best splits the problem into single commodity problems and solves these repeatedly by the Out-of-Kilter algorithm. Good locally optimal solutions can be produced by this method, even though global optimality cannot be guaranteed. Software for a microcomputer presented here as part of the design tool is capable of solving problems on realistic networks in a reasonable time. This method is embedded in a suite of computer programs which makes the input and output straightforward. Used as a design tool in the early stages of network design it gives a network-wide view of the possibilities for reducing conflict and indicates a coherent set of traffic management measures. The ideal measure would be automatic route guidance, such as the pilot scheme currently being developed for London. Other measures include a set of one-way streets and banned turns. The resulting turning flows could be used as input to the signal optimiser TRANSYT to determine signal settings favouring the routeing pattern. The project was funded by the S. E. R. C. and carried out at Middlesex Polytechnic in collaboration with MVA Systematica.

Actualmente, el espacio vial de las calles de Lima Metropolitana es diseñado de una manera poco eficiente con respecto a la inclusión de todos los usuarios del transporte urbano. La movilidad urbana presenta problemas que dan lugar a una conexión inadecuada entre los ciudadanos. Por esta razón, el presente tema de investigación consiste en realizar un rediseño geométrico de la Av. Primavera desde la Av. San Luis hasta la Av. De los precursores en el que se incluirá un nuevo carril exclusivo para bicicletas. En primer lugar, se realizan encuestas en determinada área para conocer el interés de la población por la propuesta, posteriormente determinando la demanda futura a fin de obtener la población que haría uso de la bicicleta después de una determinada cantidad de años. Posterior a ello, se propone el diseño de una ciclovía dentro del tramo analizado a través de un rediseño geométrico del espacio vial existente con el uso de los programas de diseño Autocad y Sketch-up. Además, se realiza una comparación del espacio asignado para áreas verdes, autos, ciclistas y peatones por áreas y secciones del escenario actual y el escenario propuesto con el propósito de garantizar un mejoramiento en el espacio vial. Finalmente, se realiza la validación de la propuesta mediante un análisis del tiempo de viaje y del área de arborización urbana, de modo tal que se puede verificar que no exista ningún efecto negativo a causa del rediseño geométrico. / Currently, the road space of the streets of Metropolitan Lima is designed in an inefficient way with respect to the inclusion of all users of urban transport. Urban mobility presents problems that lead to an inadequate connection between citizens. For this reason, the present research topic consists of carrying out a geometric redesign of Av. Primavera from Av. San Luis to Av. De los precursors, which will include a new exclusive lane for bicycles. In the first place, surveys are carried out in a certain area to find out the interest of the population in the proposal, later determining the future demand in order to obtain the population that would use the bicycle after a certain number of years. Subsequently, the design of a bicycle lane within the analyzed section is proposed through a geometric redesign of the existing road space with the use of the Autocad and Sketch-up design programs. In addition, a comparison is made of the space allocated for green areas, cars, cyclists and pedestrians by areas and sections of the current scenario and the proposed scenario in order to guarantee an improvement in the road space. Finally, the proposal is validated through an analysis of the travel time and the urban tree area, so that it can be verified that there is no negative effect due to the geometric redesign. / Tesis
